Indian concrete equipment users are setting records with the synchronised use of high-capacity equipment.
Demand for concrete equipment is looking up. "We have observed a steady increase in demand for concrete equipment in the past few years from companies developing infrastructure projects," says CR Jyothiraj, General Manager, Concrete Equipment Business Unit, Sany India.
"The Government of India’s focus on improving Indian infrastructure has paved the way for roads projects to be awarded and concreting equipment is in high demand,"says VG Sakthikumar, Managing Director, Schwing Stetter India, Convenor for Membership Committee, ICEMA, and Chairman of the Mechanisation Committee, Builders Association of India.
According to Ranjit More, Managing Director, Universal Construction Machinery,"Most of the current demand is for road development, industrial construction and real-estate development. Demand from builders has especially seen an upswing, with some demanding reversible drum mixers of 15-20 cu m capacity, a step up from the smaller machines they used to deploy."
The industry is positive about its future prospects. "We are sure that after the formation of a new government at the Centre, there will be a boost in government spending and lot of new projects will start, which will further enhance demand for our innovative concreting equipment products," says Kalpesh Soni, General Manager, Marketing, KYB Conmat.
Happy medium
"Demand for mid-sized 30-45 cu m batching plants is on the rise as is demand for 20-30 cu m mobile plants," says More. He attributes the higher demand for mid-sized machines (as opposed to larger-capacity machines) to their suitability to the size of projects being implemented, construction companies’ fragmented approach to increasing capacity, and slow lending by non-banking financial corporations (NBFCs), compelling construction companies to rely on their internal cash flow. "If lending by NBFCs were to pick up, it would probably boost demand for equipment," he adds. Soni expects this trend to persist. "Given the thrust on infrastructure development, we anticipate higher demand for our mid-sized batching plants from the rail, metro-rail, roads, airport, water bodies and real-estate sectors," he says.
Bigger is better
"We are seeing increased demand for bigger-capacity batching plants, concrete mixers, concrete pumps and truck-mounted boom pumps to speed up the implementation of projects and meet the need for higher productivity and reach, at a lower operating cost,"says Sanjay Saxena, Senior Vice President, Heavy Equipment and Concrete Business, Sany India.
To cater to this demand, Sany has introduced a new-generation series of batching plants of 90 to 300 cbm per hour capacity, the HZS series, with twin-shaft mixing technology batching plant. The company has also introduced 62-m, truck-mounted boom pumps in the market, the longest currently available in India, and a new series of concrete mixers with 10 cu m capacity.
Connected equipment
Customers are increasingly demanding connected equipment and want to tap the benefits of IT to better operate and monitor their equipment, shares Jyothiraj. Sany offers state-of-the-art technology that empowers customers by giving them complete control over their equipment fleet.
"Digitalisation in equipment across all categories (concrete batching plants, concrete pumps, concrete transit mixers and concrete self-loading mixers) is a current trend in demand,"observes Sakthikumar. Schwing’s digitalisation innovations include Schwing Infra IoT In, IoT ready and IoT abled.
At Universal Construction Machinery, a conscious attempt to educate customers on using technology to control multiple machines remotely has paid off, according to More.
"Customers are receptive to our range of smart machines with inbuilt SCADA systems that can be managed remotely by means of laptops or smartphones."
Record concrete pour in Andhra Pradesh
Three Sany 120 cu m batching plants installed by Navayuga Engineering at the Polavaram dam project site in Andhra Pradesh were part of an entry in Guinness World Records for the production of 32,100 cu m of concrete – the most concrete produced and poured in 24 hours continuously. In all, 3.4 million cu m of concrete are needed for this ongoing multipurpose dam for the irrigation department of the state. At the Polavaram site, Navayuga Engineering is operating three 120 cu m Sany twin-shaft batching plants. These new-generation plants allow optimum batch size, have an intermediately aggregate weighing and discharge system, additional waiting hopper and a separate cement and fly-ash weighing system that give the customer 15 per cent higher productivity, 15 per cent less power consumption and 20 per cent lower operating cost for needing fewer spares than conventional batching plants of the same capacity.
Choice of pumps
The Sany 62-m boom pump working at the Polavaram dam project site in Andhra Pradesh offers all the features of Sany higher-capacity boom pumps such as intelligent boom technology with one button stabilisation, boom anti-vibration technology, anti over swing technology, energy-saving technology, one button for low/high pressure changeover, self-diagnosis of faults, etc.
"Users are more aware of global technological advancements in concreting equipment and are willing to adopt such technologies for higher productivity, efficiency, greater convenience and lower operating costs," remarks CR Jyothiraj, General Manager, Concrete Equipment Business Unit, Sany India.
"We use truck-mounted, 50 m boom concrete pumps for our high-rise projects and trailer pumps for lower heights, says Ashok Gupta, Chairman & Managing Director, Ajnara India. "Pumps drastically cut down on the need for manual labour to transfer concrete on a construction site. We prefer pumps fitted with a split panel electrical system, a hydraulic system with manual overrides and 5 Z fold boom sections with a 9-inch barrel size. For either pump, care is important while knowledge of the functioning of a pump and concrete is essential to optimise efficiency."
Building a 196-m RCC dam in 196 days
HCC made use of roller compacted concrete (RCC) to construct the 521-m, 160-MW Teesta IV Low Dam in the Brahmaputra basin for the NHPC, marking the third time the technology has been used in India after the Ghatghar and the Middle Vaitarna dams. RCC has the same ingredients as conventional concrete but in different ratios, increasingly with the partial substitution of fly-ash for Portland cement. Also, the produced mix is drier and essentially has no slump.
For the Teesta IV Low Dam, HCC needed a huge set-up for the continuous feeding of concrete. It set up a four-stage crusher plant to produce over 4,000 tonne of aggregate everyday (at peak time) in four different size fractions – 50 to 25 mm, 25 to 12.5 mm, 12.5 to 5 mm and 5 to 0 mm – with silos for storing and procession aggregates and three fully automated batching and mixing plants equipped with powerful twin-shaft mixers with the capacity to produce over 120 cu m per hour of RCC (one was kept as backup), chilling plants and ice flex manufacturing plants. An inundation system of 4,000 tonne per day capacity helped reduce the temperature of aggregates before mixing. All these plants were connected by a web of conveyor belts covered from top to reduce dust pollution, to produce and drop the RCC at the dam location.
The dropped RCC was collected in dumpers standing on the dam body, relayed to the required location and poured. Once sufficient quantity was gathered, it was spread by dozers into over 300-mm thick layers and compacted with 10-tonne rollers. A nuclear density gauge was used to test the compactness of the RCC. On an average, 858 cum per day of concrete was placed. Thereafter, retarders helped keep alive each concrete layer until the next layer was laid.
Additional equipment needed to source the raw material included bulker trucks to bring 115 tonne (210 tonne at peak time) of fly-ash daily from 320 km away, and around 75 tonne (135 tonne at peak time) of cement from 50 km away, and dumper trucks to bring 2,500 tonne of boulders from around 25 km away. Hydras and tower cranes were used to lift and place the steel shuttering.
"Maintaining this equipment and finding space for it in the confined area of concrete placement was critical, and a big challenge," says Santosh Kumar, Project Manager, HCC. However, "adopting RCC technology helped reduce construction time by more than half, in this case to a record 196 days, and lower the construction cost by nearly 5-30 per cent, compared to conventional concrete gravity dams, depending on the size of the dam."
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:
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.
