Preservation of the environment and conservation of the rapidly diminishing natural resources is the essence of sustainable development. Recycling of concrete from the Building Demolished Waste(BDW) to produce aggregates suitable for structural and non-structural applications is fast emerging as a commercially viable and technically feasible operation.Self-Compacting Concrete (SCC) is considered as a concrete which can be placed and compacted under its self-weight with little or no vibration effort, and which is at the same time, cohesive enough to be handled without segregation or bleeding. It is used to facilitate and ensure proper filling and good structural performance of restricted areas and heavily reinforced structural members.The use of Recycled Concrete Aggregate (RCA) in construction works is a subject of high priority in building industry throughout the world and it is a good solution to the problem of an excess of waste material, provided that the desired final product quality is reached. This reduces the consumption of the natural resources as well as the consumption of the landfills required for waste concrete. The technology today has advanced so far that it is forcing us to think in terms of ‘sustainability’. Ductility of concrete is provided with fiber reinforced cementitious composites, because fibers bridge crack surfaces and delay the onset of the extension of localised crack.Research significanceAn attempt has been made in the present investigation to develop a standard grade Self Compacting Concrete without and with polypropylene and glass fibers and without and with recycled aggregate. The present work provides very useful information for the practical use of fibrous self compacting concretes in the field, employing recycled aggregate form Building Demolished Waste (BDW).Properties of SCC in fresh stateA concrete mix is called Self Compacting Concrete if it fulfills the requirement of filling ability, passing ability and resistance to segregation. The filling ability is the ability of the SCC to flow into all spaces within the formwork under its own weight.Passing ability is required to guarantee a homogenous distribution of the components of SCC in the vicinity of obstacles. The resistance to segregation is the resistance of the com-ponents of SCC to migration or separation and remains uniform throughout the process of transport and placing. To satisfy these conditions EFNARC has formulated certain test procedures.IngredientsOrdinary Portland cement of 53 grade (compressive strength not less than 53 Mpa) was used in the study. The cement was selected as per IS-12269. Fine aggregate was standard river sand procured locally and was confirming to zone-II as per IS-2386. Crushed granite was used as coarse aggregate. The aggregate was passed through standard sieves of 16mm and retained on 4.75mm sieve. Recycled aggregate from building demolished waste was crushed and classified before use. For qualifying the utility of recycled aggregate in concrete, the important parameters like bulk density, voids ratio, specific gravity, water absorption, crushing and impact value, angularity and IAPST were determined based on IS Codal provisions. There properties were determined for different replacement of Recycled Concrete Aggregate (RCA) in Natural Aggregate (NA). The properties are shown in Table 1.Tests on FRSCRACThe slump flow equipment is currently used widely in concrete practice, and the method is very simple and straight forward. Thus the H-flow combined with T50 was selected as the first priority test method for estimating the filling ability of FRSCRAC. The V-funnel or Orimet tests are recommended as second priority alternatives to the T50 measurement. The passing ability of fresh SCC can be tested by U-box or J-ring. The basic properties of SCC without and with fiber and/or recycled aggregate are shown in Table 2. The fresh properties of SCC and FRSCC are suggestive of confirmation with the EFNARC Specifications.The source of fly ash used in the experiments was from a local coal fired thermal power station, where flyash is evolving out as a bye-product. The specific gravity was 2.05 with silicon dioxide content above 92 per cent. The fly ash was used as a partial replacement for cement. Conplast SP 337 superplasticizer and Viscosity Modifying Agent (VMA) were added in optimum dosages for improving the strength and workability properties of SCC. The Nansu mix design procedure is adopted to develop M40 Grade Concrete for different replacements of recycled aggregate in natural agg-regate and without or with fiber additions. The ingredients are shown in Table 3. The Glass Fiber (GF) is Cem-Fil Anti Crack and its specific gravity is 2.6 and the specific surface area is 105 m2 /kg. Poly Propylene Fiber (PF) with a diameter of 20-200 ?m, modulus of elasti-city 5-10 Gpa and tensile strength of over 500-750 mpa was used.Experimental programAn experimental program was designed to compare the strength properties of self- compacting concrete using recycled aggregate and without or with fiber addition. Cubes, cylinders and prisms of standard dimensions were cast and tested to determine the compressive strength, split tensile strength, flexural strength and modulus of elasticity of Fiber Reinforced Self- Compacting Concrete (FRSCC) using Recycled Aggregate (RA) from Building Demolished Waste (BDW).Casting and Testing of specimensThe influence of recycled aggregate and fiber on the behavior in compression, split tension and flexure is being investigated. 150×150 mm cubes for compressive strength, 150 mm diameter and 300 mm height cylinders for split tensile strength and 100x100x400 mm prism specimens for studying the modulus of rupture were employed. The program consisted of casting and testing a total number of 54 cubes, 54 cylinders and 54 prisms cast in 9 batches. Of these 54 cubes, 18 cubes corresponding to each Natural Aggregate (NA), 50 per cent Natural & Recycled (NARA) and 100per cent Recycled Aggregate (RA). Of these 18 cubes, six cubes correspond to each no fiber (WF), with PF and with GF additions. Similarly additional 54 cylinders (18 with NA, 18 with NARA, and 18 with RA) were cast for examining the stress-strain behavior of M40 grade for different fibers. The mix was designed as per modified Nansu method of mix design. All the specimens were demoulded after 24 hrs and kept in water for curing for 28days.The specimens were capped using plaster of paris to ensure plane-testing surface. Tinius Olsen Testing Machine (TOTM) of capacity 2000 KN was used for testing the specimens under standard load rate control. While testing, precautions were taken to ensure axial loading. For flexural strength standard three point loading was adopted. The modulus of elasticity of concrete was determined using compressometer setup and tested under TOTM.Discussion of test resultsThe results obtained from the detailed experimental program conducted on SCC without and with fiber are discussed. Table 4 shows the details of various mechanical properties viz., compressive strength, split strength and flexural strength for self-compacting concretes. The optimum fiber content was utilized through out the experimentation and this was based on initial strength and flow studies.Compressive strength of FRSCRAC
The mechanical properties of NA, NARA, and RA concrete cast without and with fiber additions are shown in Table 4.Addition of fibers has definitely increased the com-pressive strength, though marginally. The percentage increase in strength with fiber addition is plotted in Fig 5. It can be noted that the percentage increase is marginal. It is 1.90 per cent, 2.01 per cent in case of NA, 1.03 per cent, 1.62 per cent in 50 per cent Natural-Recycled Aggregate(NARA) and 0.94 per cent, 1.22 per cent in Recycled Aggregate(RA) with Polypropylene Fiber Reinforced Self-Compacting Concrete and Glass Fiber Reinforced Self-Compacting Concrete respectively. It can hence be concluded at this stage that fiber additions do not increase the compressive strength much.
Influence of fibers on split tensile strengthThe tensile strength of SCC is relatively much lower than its compressive strength because, it can be developed more quickly with crack propagation. Hence, it is important to improve the tensile strength of such a concrete. The variation of split tensile strength with fiber addi-tions is shown in Table 4. The increase is 14.19 per cent, 17.74 per cent in Natural Aggregate (NA), 9.97 per cent, 14.09 per cent in 50 per cent Natural-Recycled Aggregate (NARA) and 6.25 per cent, 11.72 per cent in Recycled Aggregate (RA) with GFRSCC and PFRSCC respectively (Fig 6). It can hence be inferred from the above that the fiber additions has a pronounced increase in the split tensile strength of self compacting concrete.Influence of fibers on flexural strength
Table 4 & Fig 7 show the details of the percentage increase in flexural strength for fiber additions. There is an increase in flexural strength of fibrous concretes as compared to no fiber concretes. The values are close to 0.7 as given by IS code for the relationship between flexural strength sqrt (fck) for normal concrete. The value of flexural strength to is more with polypropylene and glass fibrous concretes compared to no fiber concretes. From Fig 7, it is clear that there is an increase of 3.15 per cent, 13.32 per cent in Natural Aggregate(NA), 2.93 per cent, 9.57 per cent in 50 per cent Natural-Recycled (NARA) and 2.31 per cent, 8.96 per cent in Recycled Aggregate(RA) with GFRSCC and PFRSCC respectively. At this stage it may be concluded that the bending behaviour is greatly improved with glass fiber additions in self com-pacting concrete.Influence of fibers on modulus of elasticityThe brittle behavior of SCC is known. The fiber addition in such concretes modified the stress-strain behaviour of plain concrete. Using a compressometer setup and under compression the stress-strain values are evaluated and curves were drawn for the initial elastic portions. The Modulus of Elasticity (E) was calculated, following the specifications as laid by IS Code 516-1999. Table 4 shows the details of the values of modulus of elasticity for self-compacting concrete for Natural(NA), 50per cent Natural-Recycled (NARA) and Recycled Aggregate(RA) and without & with fiber respectively. It may be concluded that the addition of fiber in general increased the value of Modulus of Elasticity (E) of self-compacting recycled aggregate concrete. These values were close to 5000*vfck in case of no fiber concrete and higher in case of fibrous concretes.ConclusionsBased on experimental study on Fiber Reinforced Self Compacting Concrete (FRSCC) using recycled aggregate the following conclusions can be drawn.??From the properties of RCA it can be concluded that the coarse aggregate obtained from crushing BDW can be used for structural concrete works. This confirms the fact that RCA is in no way inferior to NA.??Self Compacting Concretes could be developed with recycled aggregate using high powder content, lesser quantity of coarse aggregate, high range super plasticizer and VMA to provide stability and fluidity to the concrete mixes.??There is a marginal increase in compressive strength, very good increase in the split tensile strength and a good increase in the flexural strength of FRSCRAC. The increase in split tensile and flexural strength is more in the case of glass fiber as compared to polypropylene fiber.??The relationship between compressive and split tensile strength and flexural and characteristic compressive strength for without and with fiber is suggested.??The fibrous specimens failed only by splitting of the fiber and there was no deboning of fibers noticed in any of the specimens.

Two cement concrete pavement roads covering a total stretch of 2.2 km in Akhoya village were inaugurated on 27th June 2026 by MLA Nuklutoshi Longkumer, who attended as the special guest. The project comprises the one km L Pangersowa Road and the one point two km Longchara Junction to RC Chiten Jamir Memorial Government High School road. A formal programme followed the inauguration at the school auditorium.
A technical report was presented by Er Waloniba of the Urban Engineering Wing-III, Kohima, which stated the project was sanctioned in March 2026 under the Special Assistance to States for Capital Investment scheme for 2025-26 at a sanctioned cost of Rs 29.1 million (mn). The work order was issued to M/s Ensign Construction on thirtieth April 2026 with a stipulated completion period of 12 months. Work commenced on fourth May 2026 and was completed on sixth June 2026, with the contractor and team finishing the tasks in around two months. The project included a single-lane cement concrete pavement with side drains, two slab culverts and breast walls at required locations.
Longkumer acknowledged the Chief Minister, the advisor for urban development, contractors and other stakeholders for the allocation and support, and he commended the contractor for early completion. He noted that cooperation from landowners and the community had been important in resolving land related issues that can otherwise delay developmental works. He emphasised that planned developmental activities carried out with collective effort would enable more projects to be implemented successfully.
The headmaster of RC Chiten Jamir Memorial Government High School, I Chubasenba Longkumer, outlined the school background, noting it was established in 1962, was earlier known as Government High School Changtongya and was renamed in 2014. Local representatives said the improved approach roads would ease access for students, staff, patients and the general public and fulfil a long standing aspiration of residents. A dedicatory prayer was offered by the pastor and the programme concluded with a ribbon cutting attended by village council and town council representatives.
Indian Cement Review (ICR) and Fuller Technologies brought industry, policy and technology leaders together to discuss how cement innovation can drive green construction at scale, writes Rakesh Rao.
India is building at a pace few countries can match. Highways, airports, housing, logistics parks, industrial corridors and urban infrastructure are reshaping the country’s economic geography. But beneath this growth story lies a difficult question: can India continue to build at scale without locking itself into a high-carbon future?
That question formed the core of an online panel discussion titled “Driving Green Construction Through Cement Innovation”, organised by Indian Cement Review (ICR) in association with Fuller Technologies as the Presenting Partner on June 25, 2026. The webinar brought together experts from cement technology, R&D, global industry platforms, building performance policy and international development cooperation to examine how low-carbon cement and material innovation can accelerate India’s green construction transition.
The discussion came at a crucial time. India has committed to achieving net-zero emissions by 2070 and reducing the carbon intensity of its economy by 45 per cent by 2030. At the same time, the country’s construction sector is expanding rapidly, driven by urbanisation, infrastructure development, housing demand and industrial growth. Cement, as one of the most widely used construction materials, sits at the heart of this transition. It is indispensable to development, but also central to the challenge of reducing embodied carbon in buildings and infrastructure.
Moderated by Nitika Krishan, Senior Urban Infrastructure and Sustainable Policy Consultant, the panel featured:
- Kiranmai Sanagavarapu, Director, Low Carbon Solutions, Fuller Technologies;
- Dr Hemantkumar Aiyer, VP and Head R&D, Nuvoco Vistas Corp Ltd;
- Devika Wattal, Innovation Lead, Global Cement and Concrete Association (GCCA);
- Dr Sunita Purushottam, MD, GBPN India (Global Buildings Performance Network); and
- Vaibhav Rathi, Senior Technical Advisor, GIZ (the German Agency for International Cooperation)
Setting the tone for the discussion, Nitika Krishan underlined the scale of the challenge before the sector. “The question before us is no longer whether we build, but how we build sustainably,” she said. She pointed out that construction accounts for nearly 40 per cent of global energy-related carbon emissions when both operational and embodied carbon are considered. Cement production, she added, remains one of the hardest industrial processes to decarbonise.
For India, this is not merely an environmental issue. It is a development issue, a competitiveness issue and increasingly, a market issue. As one of the world’s largest cement producers and among the fastest-growing construction markets, India’s material choices will influence the carbon trajectory of its built environment for decades. As Krishan observed, sustainability solutions in economies such as India must not remain limited to laboratory success. They must be scalable, commercially viable and practical at national level.
The innovation gap: From technology to market
Experts believe that there is a need to bridge the innovation gaps for making decarbonisation in cement and concrete scalable. Devika Wattal of GCCA, explained, “The starting point must be the core cement manufacturing process itself. The first and foremost is the heart of our process, the heart of cement manufacturing. How do we reduce clinker? That is always a topic where industry is working very intrinsically.”
Clinker reduction remains one of the most important pathways for lowering emissions in cement. Since clinker production is energy-intensive and chemically emits carbon dioxide, reducing the clinker factor through supplementary cementitious materials (SCMs), blended cements and new chemistries can have a significant impact. Wattal also noted that carbon capture, utilisation and storage (CCUS) will have a role, though it may not be the first lever for all markets.
However, she stressed that innovation cannot stop at technology development. A solution that works in the lab must also be adaptable to industry, scalable in production and acceptable in construction practice. “It is important for that innovation to be adaptable, to be scalable, and so that it can be executed in real time,” she said.
Wattal also called for stronger enabling systems around innovation. These include performance-based standards, product-level embodied carbon databases and clearer frameworks for evaluating green materials. Without these, low-carbon cement products may struggle to compete with conventional materials in procurement and design.
R&D must balance carbon, cost and performance
Bringing in the R&D perspective into the discussion, Dr Hemantkumar Aiyer of Nuvoco Vistas emphasised that low-carbon cement development cannot be treated as a single-variable exercise. Cement must perform in real construction conditions. It must deliver strength, durability, consistency and cost competitiveness, while also reducing carbon.
“The root of understanding and balancing all these aspects lies in materials, and knowing the materials,” he said.
According to Dr Aiyer, R&D teams must understand the variability of raw materials such as fly ash, slag and clinker. Different sources produce different material behaviours. This makes mix optimisation, material characterisation and processing-property relationships critical. When performance is affected, cement manufacturers must understand how strength enhancers, admixtures and other performance chemicals interact with the material system.
He also linked material science with process efficiency. Clinkerisation takes place at extremely high temperatures, around 1,400 to 1,450 degrees Celsius. Any improvement in raw mix design, process control or energy optimisation can, therefore, help reduce emissions and cost. Dr Aiyer pointed to artificial intelligence-based optimisation, Cement 4.0 tools and advanced software as important enablers for real-time process and material control.
“The more you understand the materials, the more you can control it,” he said.
LC3: The promise is proven, the sequencing is not
Limestone calcined clay cement, commonly referred to as LC3, has attracted global attention because it can reduce clinker content significantly by using calcined clay and limestone while maintaining performance in many applications. Kiranmai Sanagavarapu of Fuller Technologies said the technology itself has already moved beyond proof of concept. Fuller Technologies has worked with calcined clay technology for nearly two decades and has seen plants running in France and Ghana. These plants, she said, are meeting local and national specifications, while the economics are beginning to make sense.
“The calciner is performing, the economics is stacking up, it is making business sense to produce,” she said.
But if the technology is viable, why has adoption not scaled faster? For Sanagavarapu, the answer lies in project sequencing. Too often, clay characterisation happens after equipment is specified. This, she warned, is a backward approach because calciner design depends on clay mineralogy, kaolinite content, iron levels, reactivity, moisture and other variables.
“If you don’t know what your deposit looks like before you commit for the equipment, you are, in a way, going blind into designing,” she said.
She also identified permitting and plant integration as major bottlenecks. Environmental clearances, mining permissions and local regulatory approvals must begin early. Similarly, calcined clay must be integrated into existing grinding, blending and logistics systems from the design stage, not treated as an afterthought during commissioning.
India already has IS 18189:2023 standard for LC3, but Sanagavarapu pointed out that the standard is not yet visible enough in procurement documents. “The gap between what is technically being permitted and what the procurement is asking is the single biggest bottleneck,” she said.
In her view, successful scale-up depends on getting the sequence right: clay characterisation first, permitting in parallel, standards aligned with construction, and integration built into plant design.
India’s LC3 journey: Progress, but demand remains thin
Providing details of India’s LC3 commercialisation experience, Vaibhav Rathi of GIZ noted that JK Cement carried out the first commercial production of LC3 at its Rajasthan plant, followed by JK Lakshmi Cement three months later. These initiatives were supported by the International Climate Initiative of the Government of Germany, with IIT Delhi contributing deep institutional knowledge on LC3 research and BIS certification.
Rathi said India’s early experience has produced clear lessons. One of the biggest was the need to build capacity among regulators. While BIS certification existed, State Pollution Control Boards were unfamiliar with the technology and unsure about the approval pathway.
“The capacity building is not just needed amongst the producer and the users of the cement, but also the regulators who are working with this technology for the first time,” he said.
He also highlighted the need for better information on China clay deposits. Since China clay is currently classified as a minor mineral, centralised data on availability, quality and location is limited. If cement manufacturers are to adopt LC3 at scale, stronger mineral intelligence will be important.
The third issue is demand. LC3 has already been used in projects such as Palava City in Mumbai and Noida International Airport, but these remain limited examples. “It is in a chicken and egg situation,” Rathi said. “Cement companies are saying we need more demand, and users are saying there is not enough cement available.”
Public procurement, he suggested, could help break this cycle. If agencies such as CPWD and other public bodies begin testing, accepting and specifying LC3, it could create the market confidence needed for cement companies to invest in production and storage.
Building codes must catch up with innovation
Dr Sunita Purushottam of GBPN India argued that material choices will determine built environment emissions over the long term, but India’s current policy signals remain fragmented. Although LC3 has received BIS recognition, she pointed out that building codes, municipal bylaws, schedules of rates and sustainability codes do not yet provide uniform guidance on low-carbon cement.
“The current cement regulations are largely prescriptive and favouring traditional materials,” she said. This limits the ability of alternative materials to compete on performance, durability and emissions.
Dr Purushottam also raised the issue of taxation. Cement, including LC3, currently falls under the same GST bracket as conventional cement. A differentiated tax structure, she argued, could help accelerate market adoption. “In order for the market to demand LC3, that differentiation in the GST could go a long way,” she said.
She noted that green building certifications such as IGBC and GRIHA are already creating demand for low-carbon materials by assigning points for embodied carbon and sustainable material use. However, she said large-scale adoption will require regulatory mandates, particularly through building codes and state-level notifications.
She also cautioned that low-carbon cement alone does not solve the entire building performance problem. A material may reduce embodied carbon, but the operational carbon of a building depends on thermal performance, design, insulation and energy use. “The energy part has two elements,” she said. “One is the embodied carbon of the material itself, and the other is the operational carbon.”
Collaboration is the bridge between invention and impact
Wattal said GCCA sees innovation as a strategic priority and works through platforms that connect industry with academia and start-ups. “There is no way we will decarbonise our sector without innovation,” she said.
However, she stressed that research must be connected to actual industry challenges. Innovations developed in isolation may fail when they encounter real-world barriers such as raw material variability, plant integration, cost, standards and finance. Start-ups, too, need industry mentorship and scale-up pathways.
Wattal also flagged the importance of finance. Even strong technologies may struggle to attract investment if there is no common understanding of bankability. “We have always put projects into, is this a bankable project? But the definition of a bankable project has never been defined,” she said.
For India, she saw strong potential in its academic and start-up ecosystem, but said the challenge lies in alignment and prioritisation. The country has the research base, industrial capacity and market size. What it now needs is a coordinated route from innovation to deployment.
There is a practical concern for cement manufacturers: how can existing plants be adapted for lower emissions without compromising reliability or commercial viability?
Kiranmai Sanagavarapu addressed, “The reliability risk in calcined clay retrofit is definitely real, but it is almost always self-inflicted. The risk arises when a new process is added to an existing circuit without properly redesigning grinding and blending configurations.”
Existing cement plants, she explained, can take two broad routes. The first is external sourcing of calcined clay combined with mill optimisation. This requires lower capital investment and can potentially move in 12 to 18 months if other conditions are in place. It may reduce emissions by around 20 to 30 per cent. The second route is integrated calcination on site, which requires higher capital expenditure and longer lead times, but provides greater control over quality, supply and emissions reduction potential.
For Sanagavarapu, the principle is simple: low-carbon retrofits must be designed with intent. “Design it with an intent properly from the start. Start in the market conditions where the economics are already working,” she said.
Circularity: The overlooked advantage
According to Vaibhav Rathi, fly ash and slag are already well established in cement and construction (C&D), but construction and demolition waste remains underutilised. “C&D waste is a growing business opportunity which not many have taken up,” he said. India’s continuous construction and demolition activity creates huge volumes of waste, much of which contributes to air pollution, land degradation and material inefficiency. With the right processing and standards, this waste can be converted into useful construction products.
Rathi also pointed out that LC3 has a circular economy dimension that is often overlooked. It can use low-grade kaolin-rich clay left behind after high-grade clay is extracted for other applications. “LC3 is not only a low-carbon solution, but also a circular economy solution,” he said.
At the same time, he cautioned that LC3 in India is not yet cheap because it has not reached scale. Site-specific techno-commercial feasibility studies, supported jointly by development agencies and industry, could help companies assess whether LC3 production makes technical and financial sense at a given location.
Dr Purushottam added that India must address both low-carbon cement and construction waste together. “Both low-carbon cement and C&D waste go hand in hand. India does not have an option but to work on both,” she said.
Dr Aiyer called for policy shifts from both government and industry, including preferential purchasing of sustainable materials, minimum supplementary cementitious material requirements in public and public-private projects, and faster regulatory implementation. “If we can fast-track the regulatory standards and their implementation on the ground, that is the way to go,” he said.
From green ambition to green construction
Cement innovation is no longer only about chemistry. It is about systems. Low-carbon cement will scale only when technology, standards, procurement, finance, regulation, education and construction practice move together.
LC3 and other low-carbon technologies have shown promise. India has early commercial examples, strong research capability and growing market interest. But mainstream adoption will depend on whether demand can be created, regulators can be capacitated, standards can be embedded in procurement, and manufacturers can see a clear business case.
For a country building at India’s scale, the opportunity is enormous. Cement will continue to be central to infrastructure and urban development. The challenge now is to ensure that the cement used in India’s growth story carries a lower carbon burden.
