What’s in store for cement?
Analysts across spectrum estimate that if only 25 per cent of houses are substituted, then the total incremental cement requirement per annum will be around 10 MT.
Housing for All by 2022 (HFA-22) is the flagship project of Prime Minister Narendra Modi. President Pranab Mukherjee, in his address to the joint session of Parliament on June 9, 2014, had announced that "by the time the nation completes 75 years of its independence, every family will have a pucca (permanent) house with water connection, toilet facility, 24×7 electricity supply and access". In order to achieve this objective, the central government launched a comprehensive scheme called Pradhan Mantri Awas Yojana (PMAY) – HFA-22. The scheme received cabinet approval in June 2015, and since then has been taking shape for faster execution.
Based on the recent activities of the government, industry experts believe the scheme is finally picking up pace and there may be a big jump in execution than what it was witnessed in the past. In this story, ICR has analysed the construction target of the government, likelihood of actual construction versus target and what is in store for the cement sector if the scheme is implemented on time. The story also analyses which states stand to benefit from this scheme and in turn which cement companies will be the beneficiaries.Increase in demand
Analysts expect incremental cement demand at 3.76 per cent per annum from the ‘Housing for All’ scheme. Based on the calculations in respect of total investment and number of housing units to be constructed under the scheme, cement players expect incremental cement demand to the extent of around 10 MT to be generated, translating into a growth of 3.76 per cent per annum. However, given the fact that cement demand growth of only 4 per cent to 5 per cent coming in from normal housing and infrastructure segments, the total cement demand growth is unlikely to touch double digits despite assumption of full scale implementation of ‘Housing for All’ scheme. Therefore, while the contribution from ‘Housing for All’ scheme is significant, it will not help the cement industry to achieve higher capacity utilisation by FY20.
To this, Pushpraj Singh, Chief Marketing Officer, JSW Cement, says, "On the back of ‘Housing For All’ scheme, we expect cement growth of about 7 to 8 per cent in the times to come." He added: "So if you see the CAGR of the industry, it has not been positive. It has been almost stabilised at whatever level it was for the last five years in South. If you look at the Eastern and the Northern regions, there has been significant growth. Combined, we expect about 6 to 7 per cent growth in the overall cement market in India."Technology
Since affordable housing require fast pace work completion, in this situation, Manju Yagnik, Vice Chairperson, Nahar Group, suggests precast construction as a cost-effective method for affordable housing. "It’s a fast and sustainable building technology for large housing projects that doesn’t compromise on quality," Yagnik says. Precast is a standard building system based on ready-made, factory-manufactured elements and intelligent connections. It provides how to style and construct an ample range of appropriate homes to fulfill the requirements of city dwellers in an exceedingly affordable timeframe and at an affordable price. Such new technologies will help boost the supply faster for affordable housing at a reasonable price. Ashok Mohanani, Chairman and Managing Director, Ekta World, believes that Indian property developers are adopting international strategies like pre-fabricated construction, dry-wall techniques, and slip-form construction for quick development. However, he thinks there’s a need to cut back the value of procurement of recent technological instruments and alternative products and materials. "Value engineering and rationalisation of the overhead costs can facilitate the sector vastly in bringing down the value of affordable housing units," he suggests. 32 million housing units on the card
The government had earlier constituted a technical group to ascertain actual urban housing shortfall in India. In a report published in 2012, the group estimated urban housing shortage at 18.8 million units. For the rural segment, the government recently outlined a scheme wherein it will build 13.2 million houses with the help of state governments and some contribution from the beneficiaries. This adds up to total housing requirement of around 32 million dwelling units (DU) by 2022. Meanwhile, total investment of $246 billion to achieve HFA-22 objectives, which means much higher private sector participation is required.What’s in for the cement sector?
Nirmal Bang, an equity research company based in Mumbai, assumed of
32 million units with an average area of Rs 400 per sq ft at an average construction cost of Rs 250 per sq ft. Nirmal Bang has estimated how much incremental cement demand HFA-22 can generate. The method they have used is based on the total investment and cement intensity of the project. Real estate developers that they connected believe that each housing unit will cost on an average Rs 1,250 per sq ft. Out of this, total construction cost is Rs 700 per sq ft and cement cost is
Rs 100 per sq ft. This tallies with general cement requirement of 20 kg per sq ft for construction of individual housing units. The key challenge in estimating the incremental cement demand and to understand how much this HFA- 22 construction will substitute individual house building in the country. Even if industry estimates that if only 25 per cent of houses are substituted, then total incremental cement requirement per annum will be 10 MT. This is a sizable addition to cement demand at 3.76 per cent.
However, ICICI Securities estimates differ from Nirmal Bang. As per ICICI Securities, even if one estimates only 20 per cent of houses to be constructed under PMAY get completed by 2022, assuming average size of the house 270 sq ft and 18 kg of cement requirement per square feet, it will give total cement requirement of approximately 27 MT by FY22.Companies to benefit
Based on the earlier success of housing construction, analysts believe that PMAY – rural has more potential in states like Uttar Pradesh, Bihar and West Bengal. Cement companies with higher exposure in the eastern and central regions (like UltraTech Cement, Shree Cement, Dalmia Cement and Birla Corporation) will benefit from the same. Under PMAY – urban scheme, states like Tamil Nadu, Madhya Pradesh, Andhra Pradesh and Maharashtra will stand to benefit. Companies with higher exposure to the southern region (like Dalmia Cement, Ramco Cements and India Cements) will benefit from the same.
It is expected that the share of infrastructure in overall cement demand would increase from the current 18-20 per cent to 22-24 per cent over the next five years, led by increased government spend. Over the last few years, weak macroeconomic environment along with several regulatory issues have impacted spending on infrastructure. However, increase in project announcement along with pick-up in execution suggests a sign of revival in the sector.
In addition, with general elections approaching in the next 18 months, it is expected that the project execution pace to improve further. Within infrastructure spends, industry expect roads and highways, railways, metros, airports, irrigation and urban infrastructure to drive higher growth. Analysts estimate a huge 160-190 MT potential cement demand from planned government infrastructure projects.
That said, India’s 17 states are expected to go for assembly election by FY20, which has likely consumed approximately 142 MT (around 50 per cent of cement demand) of cement in FY17. Five states in FY19 and nine states in FY20 are expected to go for state election.The disparity
Housing shortage in India is experienced by lower income group, which makes subsidy model redundant Housing schemes in the past have failed as the subsidy model doesn’t work, because the income level of homeless people is so low that they cannot afford to build a house even with the help of subsidy from the government. Based on studies conducted by the government, the housing need arises from the congestion in the house rather than homelessness.
Based on the government studies, around 80 per cent of total requirement comes from congestion in the house, which means the number of married couples in the house is more than the number of rooms available. This is a common phenomenon in urban areas, and because of the same, slum redevelopment projects take a huge time to take off as the density of population living in the area is high.
Moreover, the studies further highlight that 96 per cent of total requirement is from people coming under economic weaker section and lower income group categories. The definition of economic weaker section then was household with income below
Rs 5,000 per month and the same for lower income group was income between
Rs 5,000 to Rs 10,000 per month. This clearly shows that interest subvention scheme is not likely to address the housing problem as the income bracket of population facing housing shortage will have affordability issues.Progress of PMAY
As of now, 35 MoAs have been signed with 30 states and 5 union territories;
4,317 cities (472 Class I cities) have been selected in 35 states and union territories for inclusion under the scheme. Till now, the government has considered 7,474 projects for construction of 37 lakh houses for the economic weaker section in 35 states and union territories involving central assistance of Rs 2 lakh crore.
Meanwhile, of the Rs 57,000 crore central assistance, Rs 13,149 crore as a part of the first installment has been released to the concerned states against approved projects. As per the Ministry of Housing and Urban Affairs, at present only 3 lakh dwelling units have been constructed so far and another around 13 lakh housing units are under construction.
The industry has added cement capacities at 10.2 per cent CAGR over past decade; while demand clocked about 6.2 per cent CAGR. This has led to increase in surplus capacities from 34 MT (14 per cent of total capacity) in FY10 to 129 MT (31 per cent of capacity) in FY17. Utilisation levels also declined from peak of 98 per cent in FY07 to 69 per cent by FY17. Krupal Maniar, CFA, ICICI Securities, believes that up-cycle would be slow, gradual and elongated as we expect capacity addition at 3-4 per cent CAGR over next five to six years.
Increasing greenfield plant capex cost and rising entry barriers (like mine auction, regulatory clearances) are unlikely to push supply additions significantly. ICICI Securities expect cement demand to clock approximately 6 per cent CAGR (still lower than/in-line with GDP growth), resulting in gradual but steady improvement in utilisations over next five to six years. The Government focus on rural economy and higher infrastructure spends is likely to improve demand for the sector. Accordingly, Dharmesh Shah, Research Analyst, ICICI Securities, says "we expect utilisation to improve gradually by 500 bps to 74 per cent in FY20E."More M&A deals in the offing
The cement industry has seen some consolidation in recent years due to rising overcapacity, longer gestation periods (in securing various government/environment clearances, acquiring land), higher costs (elevated land costs) and issues relating to debt servicing. Some of the key deals have been UTCEM acquisition of JPA cement assets, Nirma’s acquisition of Lafarge cement business in India, and Birla Corp’s acquisition of Reliance Cement. The due diligence for ACC-ACEM merger is also on. Binani Cement and Murli Industries are under NCLT restructuring with Dalmia Bharat recently announcing the acquisition of Murli Industries.– RAHUL KAMAT

Satish Maheshwari, Chief Manufacturing Officer, Shree Cement, delves into how digital intelligence is transforming cement grinding into a predictive, stable, and energy-efficient operation.
Grinding sits at the heart of cement manufacturing, accounting for the largest share of electrical energy consumption. In this interview, Satish Maheshwari, Chief Manufacturing Officer, Shree Cement, explains how advanced grinding technologies, data-driven optimisation and process intelligence are transforming mill performance, reducing power consumption and supporting the industry’s decarbonisation goals.
How has the grinding process evolved in Indian cement plants to meet rising efficiency and sustainability expectations?
Over the past decade, Indian cement plants have seen a clear evolution in grinding technology, moving from conventional open-circuit ball mills to high-efficiency closed-circuit systems, Roller Press–Ball Mill combinations and Vertical Roller Mills (VRMs). This shift has been supported by advances in separator design, improved wear-resistant materials, and the growing use of digital process automation. As a result, grinding units today operate as highly controlled manufacturing systems where real-time data, process intelligence and efficient separation work together to deliver stable and predictable performance.
From a sustainability perspective, these developments directly reduce specific power consumption, improve equipment reliability and lower the carbon footprint per tonne of cement produced.
How critical is grinding optimisation in reducing specific power consumption across ball mills and VRMs?
Grinding is the largest consumer of electrical energy in a cement plant, which makes optimisation one of the most effective levers for improving energy efficiency. In ball mill systems, optimisation through correct media selection, charge design, diaphragm configuration, ventilation management and separator tuning can typically deliver power savings of 5 per cent to 8 per cent. In VRMs, fine-tuning airflow balance, grinding pressure, nozzle ring settings, and circulating load can unlock energy reductions in the range of 8 per cent to 12 per cent. Across both systems, sustained operation under stable conditions is critical. Consistency in mill loading and operating parameters improves quality control, reduces wear, and enables long-term energy efficiency, making stability a key operational KPI.
What challenges arise in maintaining consistent cement quality when using alternative raw materials and blended compositions?
The increased use of alternative raw materials and supplementary cementitious materials (SCM) introduces variability in chemistry, moisture, hardness, and loss on ignition. This variability makes it more challenging to maintain consistent fineness, particle size distribution, throughput and downstream performance parameters such as setting time, strength development and workability.
As clinker substitution levels rise, grinding precision becomes increasingly important. Even small improvements in consistency enable higher SCM utilisation without compromising cement performance.
Addressing these challenges requires stronger feed homogenisation, real-time quality monitoring and dynamic adjustment of grinding parameters so that output quality remains stable despite changing input characteristics.
How is digital process control changing the way grinding performance is optimised?
Digital process control is transforming grinding from an operator-dependent activity into a predictive, model-driven operation. Technologies such as online particle size and residue analysers, AI-based optimisation platforms, digital twins for VRMs and Roller Press systems, and advanced process control solutions are redefining how performance is managed.
At the same time, workforce roles are evolving. Operators are increasingly focused on interpreting data trends through digital dashboards and responding proactively rather than relying on manual interventions. Together, these tools improve mill stability, enable faster response to disturbances, maintain consistent fineness, and reduce specific energy consumption while minimising manual effort.
How do you see grinding technologies supporting the industry’s low-clinker and decarbonisation goals?
Modern grinding technologies are central to the industry’s decarbonisation efforts. They enable higher incorporation of SCMs such as fly ash, slag, and limestone, improve particle fineness and reactivity, and reduce overall power consumption. Efficient grinding makes it possible to maintain consistent cement quality at lower clinker factors. Every improvement in energy intensity and particle engineering directly contributes to lower CO2 emissions.
As India moves toward low-carbon construction, precision grinding will remain a foundational capability for delivering sustainable, high-performance cement aligned with national and global climate objectives.
How much potential does grinding optimisation hold for immediate energy
and cost savings?
The potential for near-term savings is substantial. Without major capital investment, most plants can achieve 5 per cent to 15 per cent power reduction through measures such as improving separator efficiency, optimising ventilation, refining media grading, and fine-tuning operating parameters.
With continued capacity expansion across India, advanced optimisation tools will help ensure that productivity gains are not matched by proportional increases in energy demand. Given current power costs, this translates into direct and measurable financial benefits, making grinding optimisation one of the fastest-payback operational initiatives available to cement manufacturers today.

Refractory demands in our kiln have changed

Radha Singh, Senior Manager (P&Q), Shree Digvijay Cement, points out why performance, predictability and life-cycle value now matter more than routine replacement in cement kilns.
As Indian cement plants push for higher throughput, increased alternative fuel usage and tighter shutdown cycles, refractory performance in kilns and pyro-processing systems is under growing pressure. In this interview, Radha Singh, Senior Manager (P&Q), Shree Digvijay Cement, shares how refractory demands have evolved on the ground and how smarter digital monitoring is improving kiln stability, uptime and clinker quality.
How have refractory demands changed in your kiln and pyro-processing line over the last five years?
Over the last five years, refractory demands in our kiln and pyro line have changed. Earlier, the focus was mostly on standard grades and routine shutdown-based replacement. But now, because of higher production loads, more alternative fuels and raw materials (AFR) usage and greater temperature variation, the expectation from refractory has increased.
In our own case, the current kiln refractory has already completed around 1.5 years, which itself shows how much more we now rely on materials that can handle thermal shock, alkali attack and coating fluctuations. We have moved towards more stable, high-performance linings so that we don’t have to enter the kiln frequently for repairs.
Overall, the shift has been from just ‘installation and run’ to selecting refractories that give longer life, better coating behaviour and more predictable performance under tougher operating conditions.
What are the biggest refractory challenges in the preheater, calciner and cooler zones?
• Preheater: Coating instability, chloride/sulphur cycles and brick erosion.
• Calciner: AFR firing, thermal shock and alkali infiltration.
• Cooler: Severe abrasion, red-river formation and mechanical stress on linings.
Overall, the biggest challenge is maintaining lining stability under highly variable operating conditions.
How do you evaluate and select refractory partners for long-term performance?
In real plant conditions, we don’t select a refractory partner just by looking at price. First, we see their past performance in similar kilns and whether their material has actually survived our operating conditions. We also check how strong their technical support is during shutdowns, because installation quality matters as much as the material itself.
Another key point is how quickly they respond during breakdowns or hot spots. A good partner should be available on short notice. We also look at their failure analysis capability, whether they can explain why a lining failed and suggest improvements.
On top of this, we review the life they delivered in the last few campaigns, their supply reliability and their willingness to offer plant-specific custom solutions instead of generic grades. Only a partner who supports us throughout the life cycle, which includes selection, installation, monitoring and post-failure analysis, fits our long-term requirement.
Can you share a recent example where better refractory selection improved uptime or clinker quality?
Recently, we upgraded to a high-abrasion basic brick at the kiln outlet. Earlier we had frequent chipping and coating loss. With the new lining, thermal stability improved and the coating became much more stable. As a result, our shutdown interval increased and clinker quality remained more consistent. It had a direct impact on our uptime.
How is increased AFR use affecting refractory behaviour?
Increased AFR use is definitely putting more stress on the refractory. The biggest issue we see daily is the rise in chlorine, alkalis and volatiles, which directly attack the lining, especially in the calciner and kiln inlet. AFR firing is also not as stable as conventional fuel, so we face frequent temperature fluctuations, which cause more thermal shock and small cracks in the lining.
Another real problem is coating instability. Some days the coating builds too fast, other days it suddenly drops, and both conditions impact refractory life. We also notice more dust circulation and buildup inside the calciner whenever the AFR mix changes, which again increases erosion.
Because of these practical issues, we have started relying more on alkali-resistant, low-porosity and better thermal shock–resistant materials to handle the additional stress coming from AFR.
What role does digital monitoring or thermal profiling play in your refractory strategy?
Digital tools like kiln shell scanners, IR imaging and thermal profiling help us detect weakening areas much earlier. This reduces unplanned shutdowns, helps identify hotspots accurately and allows us to replace only the critical sections. Overall, our maintenance has shifted from reactive to predictive, improving lining life significantly.
How do you balance cost, durability and installation speed during refractory shutdowns?
We focus on three points:
• Material quality that suits our thermal profile and chemistry.
• Installation speed, in fast turnarounds, we prefer monolithic.
• Life-cycle cost—the cheapest material is not the most economical. We look at durability, future downtime and total cost of ownership.
This balance ensures reliable performance without unnecessary expenditure.
What refractory or pyro-processing innovations could transform Indian cement operations?
Some promising developments include:
• High-performance, low-porosity and nano-bonded refractories
• Precast modular linings to drastically reduce shutdown time
• AI-driven kiln thermal analytics
• Advanced coating management solutions
• More AFR-compatible refractory mixes
These innovations can significantly improve kiln stability, efficiency and maintenance planning across the industry.
