Cement companies put up capacities in excess of demand in anticipation of increased consumption of cement on account of expected hike in government spending, which did not materialize. N. A. Viswanathan, Secretary General, Cement Manufacturers’ Association dwells on the issues dogging the cement industry and spells out what needs to be done by the government to tackle these issues.Cement industry, which has a direct co-relation of 1.1 to 1.2 with GDP, plays a pivotal role in the infrastructure development of the country. Buoyed with various infrastructure policies and schemes of the government, particularly after 1982 (partial decontrol) of cement, this industry had added substantial cement capacities year-after-year, much ahead of the actual cement demand taking place. However, the overall slowdown in the economy at 6.5 per cent in FY12, which further contracted to 5.3 per cent in the Apr-Jun quarter of 2012, one of the lowest in nine years, resulting in dampening construction activities, weakening of the rupee value against dollar and higher interest rates of borrowings, to quote a few, have made a severe dent on the growth of the cement industry, from an average growth of around 10 per cent in the last couple of years to a low growth of 5 per cent in FY11 and 6.3 per cent in FY12 respectively. For no fault of theirs, the cement industry has recently been criticised and also harshly penalised for under-utilising the cement capacity, without appreciating the ground realities and the factors which have contributed to reduced capacity utilisation. Today, because of the huge mismatch between demand and supply of cement, the country is having about 93 million tonnes of excess cement capacity created after making colossal investments. To revive the economy from its present slackening mode, it is now imperative for the government to enh-a-nce cement demand by taking some positive and concrete policy measures.The backgroundThough the cement industry has been in existence since 1914, appreciable growth in the cement production has been witnessed only after the introduction of partial decontrol in 1982 culminating in total decontrol in 1989 and delicensing in 1991. With the implementation of liberalisation policies of the government in 1991 followed by government’s thrust on infrastructure development in the country, the pace of the growth of the cement industry has been unprecedented.Exponential GrowthThe burgeoning growth of the industry can be gauged from the fact that for creating the first 100 million tonnes capacity, prior to partial decontrol era, the industry took 83 long years, whereas to reach the second and third 100 million tonnes mark, the period had substantially shrunk to 11 years and less than 4 years, respectively (see chart). Cement capacity which was 64.55 million tonnes in 1990-91 reached 340.44 million tonnes in 2011-12. Similarly, cement production went up from 48.90 million tonnes to 247.32 million tonnes during the same period.World Class IndustryIndia is the second largest cement producing country in the world, next only to China both in quality and technology. It produces about 7 per cent of the global production. In 2010, world production of cement was 3294 million tonnes. It is a matter of concern that even after attaining the second position, our per capita cement consumption is very low at 180 kg., which is much below the global average of 450 kg. (see table).Per capita consumption of cement is accepted as an important index of the country’s economic growth. Hence, there is enough potential to enhance our per capita cement consumption to match with the world average.With the adoption of massive modernisation and assimilation of state-of-the-art technology, Indian cement plants are today most energy-efficient and environment-friendly and are comparable to the best in the world in all respects, whether it is kiln size, technology, energy consumption or environment-friendliness. Industry has progressively reduced its energy consumption from 800-900 kwh/tonne clinker in 80s to 650-750 kwh/tonne clinker now. Similarly, power consumption registered a remarkable improvement from 105-115 kwh/tonne cement to 70-90 kwh/tonne cement during the said period. Presently, about 99 per cent of the total capacity in the industry is based on modern and environment-friendly dry process technology. Cement industry has now been making sincere efforts to utilise waste heat recovery in the plants.Problems plaguing the industryThere are a number of constraints and bottlenecks which are hindering the growth of this core sector industry. A few of the major concerns of the industry are discussed below:Excess cement capacity: Cement industry has been experiencing glut situation as there has been mammoth mismatch between cement demand and its supply. The industry had created the capacity on the back of government’s projection of potential cement demand arising out of the thrust given for infrastructure development in the country and the allocation of funds earmarked for the purpose. However, the cement demand, as projected, has not materialised, despite the capacity having been created well in advance after making huge investments.Acute shortage of coal: Coal is one of the major raw materials needed by the industry both in the manufacturing of cement and also for generating power. In the last couple of years, there has been a steep drop in the supply of linked coal to the cement industry from 70 per cent in FY04 to almost 39 per cent now, mainly due to diversion of coal to the power sector. Cement companies, therefore, have perforce to resort to either open market purchase or imported coal which works out to nearly 2 to 2.5 times higher than the domestic price or use of the alternate fuel like pet coke, lignite, etc. which also adds up significantly to the additional cost of production. What is worse, new capacities are not being given any coal under the Linkage Scheme and therefore there is a real fear that the shortage of the main fuel, with no assurance of its availability in future, may actually hamper the required capacity additions for future build up. With the increasing cost of coal and other input materials such as diesel, etc. the production cost of cement has gone up significantly.Inadequate availability of wagons: Rail is the ideal mode of transportation for cement industry. However, it has always been plagued by the short supply of wagons, particularly during the peak period. In addition to this, infrastructure constraints and also not factoring the points of view of the cement industry, which is one of its largest consumers, in the policies of the railways have been hampering the planned movement of cement to the consumption centres, adversely impacting the production schedule and also increasing the overall transportation cost of cement. Rail share for cement which was 53 per cent a couple of years back has come down to 35 per cent now, which is a matter of great concern both to the cement industry and the railways.Cement highly taxed: Although cement is a high volume low value product, it is one of the highly taxed commodities (60 per cent of the ex-factory price), even more than luxury goods. This is exclusive of the freight transportation, which is about 20 per cent of the operating cost. The levies and taxes on cement in India are far higher compared to those in the countries of Asia-Pacific region or even compared to the developing economies like Pakistan and Sri Lanka. Cement and steel are two major materials needed for construction of any infrastructure. However, it is ironic that the rate of VAT charged on cement and steel differs vastly. While the value-added tax (VAT) on steel is only four per cent, it is 12.5 per cent on cement/clinker which goes up to even 15 per cent in some of the states.Steep fall in cement exports: With the high incidence of government levies, infrastructure constraints at ports and the regulatory policies of the government providing encouragement for import of cement with nil custom duty, the export of cement and clinker from India has been steadily and continuously declining from 9 million tonnes in FY07 to 3.5 million tonnes in FY12, despite the fact that Indian cement industry is presently having the substantial excess capacity of cement and clinker.Use of fly ash unviable: Cement industry’s initiative and investment to the tune of more than Rs 1000 crore for effectively utilizing the industrial waste fly ash, which was otherwise posing a nuisance as a health hazard, has helped the thermal power plants in addressing and tackling the menace of fly ash related health and environmental hazards. However, power plants which had been earlier supplying fly ash to the cement industry free of cost have for the last couple of years, as per the order of the Ministry of Environment and Forests, started charging for fly ash from November 2009. The order has also made it mandatory for the cement plants having captive power plants to supply 20 per cent of the fly ash generated as free of cost to the small scale brick manufacturers, etc. within the vicinity of 100 kms of their plants. Both these have severely impacted the production cost of cement and also seriously threatened the fly ash recycling potential in the country.XII Plan – cement demand projectionsAs per the report submitted to the Planning Commission recently by the Working Group on Cement Industry for XIIth Plan, the country’s cement production and capacity is estimated to surge from 247.32 million tonnes and 340.44 million tonnes respectively in FY12 to 407.4 million tonnes and 479.3 million tonnes respectively by FY17.Future OutlookThe slackening economy will take at least one or two years to bounce back to its earlier level. This would, as a thumb rule, apply to the cement industry also. Since India has been emerging as one of the fastest growing economies in the world, the future outlook for cement looks to be bright, provided government formulates facilitating growth oriented policies so that our per capita cement consumption matches with at least with some of the developing economies.Measures for stimulating cement demandIt is imperative to bring back this core cement industry on higher and faster growth trajectory by revival of cement demand through faster growth of infrastructure sector, including roads, ports, airports, housing, irrigation projects, and so on. This would be possible particularly by bringing out more encouraging schemes for affordable housing with income tax relief and by constructing long-lasting cement concrete roads and adopting cement concrete canal lining to conserve 50 per cent precious water that presently seeps through our unlined canals. Water thus saved can be effectively utilized for our agriculture and other needs. The government’s long cherished ‘dream’ to provide ‘world-class standard roads’ can be fulfilled only if cement concrete roads and white topping (a technology on which a concrete layer is laid on the existing bitumen road) are adopted in the country on a larger scale. It is a well-established fact that cement concrete roads are long-lasting, maintenance-free for 30-40 years and today, in most of the cases, are even economical than bitumen roads in the construction stage itself and are, therefore, much-needed for the exponential growth of our economy. Further, cement roads can simultaneously resolve, without entailing any extra financial cost, a number of national issues and problems the government is grappling to find solutions even after spending thousands of crores of rupees every year. The problems which would be addressed are – (a) conservation of diesel and petrol up to 14 per cent as heavy load carriers consume less fuel on concrete roads than while plying on bitumen roads (b) preservation of precious foreign exchange being spent on the import of bitumen used in the construction of roads (c) utilization of fly ash up to 35 per cent, disposal of which is a nuisance and health hazard (d) conservation of 10 per cent electricity used for the street lights (e) protection of our quarries and mines and above all (f) generation of substantial downstream employment.Coal supply and wagon availability to the cement industry, which have become very acute and uncertain in the recent past, needs to be assured on a consistent and regular basis to the cement industry to facilitate it to meet the projected cement demand of the country.Further, the government needs to initiate certain measures in the form of providing tax incentive to the industry, reduce the overall tax value on the commodity and phase out cross subsidy on electricity, diesel and railway freight in a gradual manner. The government can also consider classifying cement as "Declared Goods" like steel having a uniform VAT rate of 4 per cent throughout the country. The overall taxation value on cement can be brought down to a level of 20-25 per cent of ex-works selling price from the current level.Tax incentive should also be pro-vided by the government for pro-moting blended cement in the larger interest of mineral conservation, waste utilization and bringing down carbon emission.Above all, level playing field needs to be provided to the domestic manufacturers to encourage cement and clinker exports by re-imposing custom duty on cement, which is nil at present. Additionally, Ready Mix Concrete (RMC) needs to be encouraged leading to bulk supply of cement and consequent reduction in pack-aging cost.It is a matter of record that even during the worst phase of economic slow-down, the Indian cement industry has surprised the economy watchers by its pace of sustained growth bucking the general trend of negative or slow growth of economy and the industry sector. It is, therefore, not too optimistic to presume that if the suggested measures are implemented, the cement industry will not only become a leader amongst the various sectors of the industry but will also emerge as a showpiece of model infrastructural growth contributing, in turn, to economic growth.

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.
