2015 will be another year of more consolidation in the cement industry where quality players may take over smaller inefficient and high cost players with weak cash flows.
As per reports, the results of the government?s initiatives have already started reflecting in the growth of the cement industry to 8.5 per cent in the first eight months of the current fiscal. If this momentum gains further, the cement demand will again pick up a double digit growth. Even with 10 per cent growth, this will accelerate the cement production by over two-and-a-half times, to 665 MT in the next ten years, i.e. by 2024, which would require a cement capacity of around 750 MT at 90 per cent utilization. This will call for an additional investment of about Rs 2.5-3 lakh crore for creating another 390 MT of cement capacity. Concretisation of roads, dedicated freight corridors, development of smart cities, metro rail projects, are some of the major thrust areas of the government, which will drive cement consumption in coming year. At the same time, as per industry sources, 2015 will be another year of more consolidation in the cement industry where quality players may take over smaller inefficient and high cost players with weak cash flows. Impact of consolidation According to Manoj Misra, Chairman and Managing Director, Cement Corporation of India, large cement players in India will use the acquisition route to enhance capacity and market share; and in the long term smaller plants will not be able survive. Says Misra, ?The top five players will hold 70-80 per cent of capacities and market in the next decade; there is expectation that more global players would come into India as they would like to get a foothold in the market as the demand will propel in the emerging economies.?
Says Prashant K Tripathy, Group Head – Manufacturing, Dalmia Cement Bharat, Cement industry has experienced more change in the last decade than its entire history. With the demand in the cement sector poised to grow over 9 per cent in the next two years, increase in prices is a huge concern. Thus, consolidation helps in stabilizing prices? Tripathy adds,?There has been and increased focus on infrastructure and development with growth in demand in housing and industrial sector, with growing Indian GDP. Entry of foreign cement players resulted in the consolidation of the fragmented industry. Large number of mergers and acquisitions were witnessed in recent years.?
Explaining to what extent this is going to alter the market structure Misra adds, ?To better serve their markets, companies will combine their operations and streamline their offerings. Efficiencies of scale allow businesses to reduce costs and prices and ease decisions for potential investors. As a business segment ages and matures, numerous companies may find themselves offering the same products, at roughly the same price and quality, to the same market. The competition drags down sales and profits, while businesses struggle to innovate and remain viable. The answer in this situation is market consolidation: the takeover of the small by the strong through outright purchase or merger. By merging or acquiring, combining operations, closing factories and reassigning workers, a firm can reduce costs and improve profit margins. In addition, cutting redundant administrative workers and combining sales and marketing divisions can significantly lessen labour and head-office costs. This action reduces competition and tends to boost prices. That?s not so good for the consumer, perhaps, but it?s a natural cyclical development in the business realm.? He further adds, ?Global giants like Holcim and Lafarge have joined hands and their estimated capacity in Indian market is now at 65 million tonne. Indian giant Aditya Birla is also in the mode of acquiring and merging with small units throughout India to maintain its leadership position. AB group has also expanded its capacity to 59 million tonne, but has plans to enhance further to maintain its leadership. Hence the cement industry will be controlled mainly by two giants. The market will be dictated by the two groups in matter of pricing and supplies.?
Speaking about the positive impact of consolidation in the cement industry, Arvind Pathak, Chief Executive Officer, Reliance Cement Company says, ?Consolidation being witnessed in the industry is good and is in the right direction. Serious players increasing stakes in terms of manufacturing capacity is a good indicator of long term growth and stability for cement markets. Large players given the available financial headroom and scale of operation are expected push the industry towards operational efficiency and better service quality to the consumers. Consolidation will ensure not only healthy competition but also high level of quality and service assurance to the end consumers.? He adds, ?The Indian cement markets are poised for unprecedented growth on the back of both infrastructure as well as growth in the housing sector. This can be witnessed in the structural changes in the Indian economy being proposed by the present government. Reliance Cement is gearing up accordingly to cater to the upcoming demand and our capacity addition plans are in line with the expected demand in the coming years.?
Says Noopur Jain, Assistant Vice President, ICRA, ?Of late, there has been some activity of acquisition in cement industry. Indian cement industry is still fragmented and can see some consolidation of assets to synergise. But I have not seen any exits by most companies except those who are facing liquidity crunch. More than consolidation, the more important input in pricing will be the demand-supply because although some sort of consolidation is happening by way of acquisitions, it is not changing the structure of the industry.?
Capacity utilization
After expanding at an average rate of 8-10 per cent in the last three decades, the cement growth in 2013-14 had dwindled to 3 per cent, the lowest in the last 20 years, due to slowdown in the economy and deceleration in the construction activities. With cement production at 256 MT against a capacity at 360 MT, the cement industry was saddled with an idle cement capacity of over 100 MT valuing a colossal dead investment of over Rs 70,000 crore at today?s cost. What will be the impact of lower capacity utilization on the industry as a whole? Says Tripathy, ?We are expecting that the capacity utilization in 2015-16 will be better than current financial year, giving a positive impact on the company bottom-line. The advantages of consolidation have been witnessed for over a decade now since sustained merger and acquisition activity in cement has led to much improvement in profitability and valuations in the sector.? He adds, ?During 2007-12, the cement capacity in India almost doubled to around 300 MTPA. Our capacity utilisation has adequate margin in the Tamil Nadu and AP plants therefore we may be able to fulfill the market demands. Our cement plants in India have grown manifolds in terms of capacity; we are also acquiring some new plants to increase the volume and expand further.?
?While it may be correct when we say the cement industry is projected to operate at 70-75 per cent in the near terms – a closer look at the expected regional performance is required. The central region where Reliance Cement is currently present is expected to operate far better than other areas. Our expectation is that the capacity utilisation in this region would be close to 90 per cent if not more and hence we foresee a positive impact on our performance,? says Pathak. He adds, ?We have current capacity of 5.8 MTPA, operating from four locations – Maihar (Satna), Kundanganj (Raebareilly), Butibori (Nagpur) and Durgapur. We have another 10 MTPA in the immediate pipeline. Capital expenditure is expected to be in the range of Rs 7,000-7,500 crore.?
Cement industry was at its all-time low in FY 14 with a marginal growth by 3 per cent and there was an excess capacity. Now we see a reversal in that trend as the demand has grown. In the first eight months of the current FY, the demand has grown by 8.5 per cent as compared to 3 per cent last fiscal. Says Jain, ?In the previous fiscal, since there was excess capacity existing, there was a slowdown in fresh capacity additions. With the demand is growing now, we expect the excess capacity to be absorbed by the industry in the next 2-3 years and expect the utilization level to improve in medium term from around 72 per cent to 78 per cent by 2017. As per industry trends, the capacity addition in the next two years is going to be in the range of 20-25 million tonne per annum. However, some of these projects will be running with delays and may face execution challenges or they may come up in the middle of the year with the effective capacity addition. I think the demand improvement will be the key for the overall utilization level to improve in future. Also the stable government at the Centre has taken steps to speed up the execution of various projects. All these are going to materialise in the coming 2-3 years.?
Jain adds, ?Although the utilisation level will improve from the current level of 70-72 per cent to 78-80 per cent in a couple of years, it will be still lower than what we saw in the peak of FY 06 and FY07 when India was witnessing a very high growth rate. That time the utilisation level touched 90s and even 100 per cent.? According to him even though there is a surplus capacity in the system, most of the cement players will keep announcing new capacities. This is because many existing plants are very old and they won?t be so efficient. So the players will set up new facilities to increase operational efficiency.
Speaking about the demand scenario, Misra says, ?The metro rail projects in Mumbai, Bangalore and Hyderabad and the expansion phase in Delhi drive cement demand in this segment. Concrete roads and national highways, rural linkage roads, development of smart cities, hydel dams, river canal lining and linkage and many other infrastructure related. Airports modernization across major cities will also expand demand. Huge demand of cement is expected to emerge as the above projects are expected to roll out in the entire country. With the huge demand coming, greenfield and brownfield units are going to be set up and by 2020 it is expected that the installed capacity in India would be 500 million tonne.? Misra adds, ?With CCI and its present operating units at Tandur in Telangana, Rajban in Himachal Pradesh (nearer to Uttarakand) and Bokajan in Assam will have the opportunity to maximize its capacity utilisation. We are in process of setting up a new clinkerisation unit at Bokajan and close circuiting at Tandur and Rajban to enhance the existing capacity.?
Challenges
Speaking about the challenges Jain says, ?On the demand side, there needs to be a big push from the government sector to speed up investment in infrastructure and housing, which is happening but it is to be seen whether this is happening on a sustainable basis. Major challenge faced by the industry is the cost. Major cost components are the freight cost, power and fuel cost and raw material cost. The raw material cost is increasing at a steady level, but the freight cost increase is steep due to increase in diesel prices and subsequent raise of freight rates by Indian Railways and other transport and logistics firms. This is happening at a time when the industry is already facing the slowdown.?
Misra is on the same page. He says, ?The rising cost of production attributed mainly due to high price of energy and coal is adversely affecting the industry. Also there is at time the issue of availability of railway rakes. Transportation at times by road and especially for loose cement movement is a challenge in front of the industry. Another aspect is the taxes which forms about 60 per cent of the price of cement (taxes/duties direct and indirect). There is a pressing need to rationalise the tax structure.?
Pathak had this to say. ?It may be observed that while the manufacturing facilities are concentrated around the limestone belts these facilities are catering to the entire nation. Cost of logistics account for over 35 to 40 per cent of the total delivered cost of cement to the end consumers. Innovations have taken place in terms of adoption of split grinding/blending facilities bringing down the cost of logistics however; availability of railway infrastructure (rakes, reach and unloading facilities), roads and fragmented transportation service providers pose a major challenge to the industry to increase efficiency in terms of total delivered cost of cement. We as an industry have to start looking at sea route and inland water ways to effectively and efficiently cater to the upcoming demand and start investing in developing these infrastructures. Says Tripathy ?Our current capacity is 20 million tonne of cement including the group plants in Odisha and newly acquired Bokaro grinding unit. We have existing plants in Tamil Nadu three lines, AP one kiln, Meghalaya one kiln and a grinding unit in Assam near Guwahati. We are currently executing two green field projects, one near Belgaum in Karnataka and the other one in Assam. These two projects will be commissioned in year 2015 and will add another 3 million tonne to our current capacity making a grand total of 23 million tonne per annum.?
However, the long term growth seems to be intact. The government?s continuous thrust on and commit?ment for, affordable housing, construction of cement concrete roads, creation of 100 smart cities, world-class infrastructure development, with emphasis on development of freight corridors and ports connectivity should give a definite fillip to the creation of more demand for cement in the country.

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.
