Mohammed Ismail, DGM Process, Bharathi Cement, speaks on the challeneges faced by refractories in India.

As a global player, what are the efficiency improvements that you observed in your products after the adaptation of refractory?
The use of refractories help in many ways in the cement industries, first and foremost it gives good life, it helps avoid unscheduled stoppages of the plant etc. So the selection of the refractory is very important to maximise the benefits. That is where we give more importance and in our plant we have been using magnesia bricks in the kiln (rich alumina content). Preheated area is one of the critical areas and that is were we have used refractories and that helped us to achieve temperatures at 1100 degree centigrade. The high alumina content that are used helped us achieve this temperature levels. It has given us a good life of 5-6 years.

The adaptations we are basically dependant on the imports. How do you see the domestic supply shaping up?
Domestic supply, especially we have been habituated to high alumina content bricks. Refractories can be divided into two parts- one is bricks, and another is monolithic castable. If we take the use of bricks, we have been using basic bricks.As basic bricks have high CCS (Cold Crushing Strength) will be higher, and it sustain in very high temperature. Along with the selection of the fuels or alternative fuels, the type of refractory to be used has also been selected. To cite an example, we use high intensive temperature producing coke as a fuel. Basic brinks are one and the same as the alumina bricks which are produced by moulding only. When installed in our kilns, the temperature can go up to around 1,500-1,600 degree centigrade. At the same time, the flame temperature will be higher than these temperatures levels. So to withstand this, we have introduced refractory.

Second part is what we call as the monolithic castable. Apart from the kiln, these are being used. We are having multi-stream – double stream preheated systems. Triple stream preheated, with six stages with a height of around 180 m. This is divided into six stages. The hot metal move from top to bottom and the cold moves from bottom to top, thus the heat exchange takes place.

As a global player you have seen the adaptation in many countries and then in India. What do you think are the challenges faced in India?
When we depend on imports the major challenge is the lead time is very hig, which is anywhere between four to six months. But if domestic supply is available then the materials can be procured within two to three weeks. Unfortunately, we are still majorly depend on imports in refractories. We are yet to see quality suppliers in the domestic market. Knowing the quality, the cement players still prefer importing.

For refractories, steel is one of the major consumers followed by chemical industry, Cement probably is a small faction. What is the demand growth for next 2-3 years?
There is high demand expected for cement as a segment is expected with the infrastructure growth push from the government. There is more concentration on developing alternative fuels also in the offing. These alternative fuels are having a very high impact on the refractory also. And cement would be one segment that can implement the alternative fuels adaptation.So there is space for significant for refractory in India.

India’s Cement Sector Cuts Energy Use, but Worker Safety Worsens

iFOREST finds efficiency gains alongside water and safety concerns

India’s cement sector has improved its energy and carbon efficiency, but rising groundwater use in water-stressed regions and deteriorating worker safety remain significant concerns, according to a report by the International Forum for Environment, Sustainability & Technology (iFOREST). The findings also highlighted weak policy implementation and gaps in sustainability reporting.

India, the world’s second-largest cement producer, uses about 2.54 gigajoules of energy per tonne (GJ/t), below the global average of 2.88 GJ/t. However, renewable sources accounted for only 5.1 per cent of the sector’s energy mix, indicating continued dependence on conventional sources.

The report assessed 18 cement companies against 107 Business Responsibility and Sustainability Reporting indicators for FY24 and FY25. The companies covered 87 per cent of India’s cement production. Carbon emissions intensity declined from 0.58 to 0.57 tonnes of carbon dioxide per tonne, but total emissions increased 4 per cent to 224.3 mn t, equivalent to about 6 to 7 per cent of India’s overall emissions.

Overall water withdrawal declined 9.5 per cent during the study period, while withdrawals in water-stressed areas, mainly in Rajasthan, increased by more than 20 per cent. Groundwater’s share of withdrawals in these areas rose from 27 per cent to 38 per cent, raising concerns about the sector’s impact on vulnerable water resources.

The sector employs about 228,000 people, including 63 per cent contractual workers, 3.1 per cent women and 0.07 per cent persons with disabilities. Women in key managerial roles earned 26.8 per cent less than men, while median pay for women workers fell 11.1 per cent in FY25 as men’s pay increased. Worker injuries rose 36.5 per cent to 359, and fatalities increased from 17 to 22, with workers accounting for more than 90 per cent of deaths.

iFOREST recommended cement-specific reporting guidance, standardised metrics, mandatory production disclosure and third-party verification. It also called for environmental, social and governance policies to be integrated into business strategies and implemented more effectively on the ground.

Ambuja Cements expects its sales volumes to grow faster than the cement industry during the second half of fiscal year 2027, as it seeks a recovery in institutional demand after a weak first half. The Gautam Adani-owned company is aiming to rebuild volumes while protecting profitability.

The company reported a 90 per cent year-on-year decline in consolidated net profit attributable to owners of the parent to Rs. 1.93 bn for the quarter ended 30 September, from Rs. 17.74 bn a year earlier. The previous year’s profit included a reversal of income-tax provisions worth Rs. 16.97 bn. Revenue from operations rose marginally to Rs. 91.66 bn from Rs. 91.3 bn.

Trade volumes increased 8.6 per cent year-on-year in the September quarter, but weaker institutional sales left overall volumes broadly unchanged. Ambuja Cements expects both trade and institutional sales to turn positive in the third and fourth quarters. Trade sales are made through dealers and distributors, while institutional or business-to-business sales involve bulk supplies to infrastructure developers, government projects and real estate companies.

The company had earlier reduced institutional sales that did not generate adequate returns. It now plans to rebuild the business selectively, while continuing to prioritise trade sales and higher-value products. Trade accounted for 74 per cent of sales in the quarter, up six percentage points from a year earlier, while premium products increased to 37 per cent of trade sales from 35 per cent. Blended cement’s share rose to 82 per cent from 77 per cent.

Ambuja Cements commissioned 4.6 mn t of capacity during the quarter. Another 3.2 mn t at Bathinda in Punjab and Jodhpur has stabilised, with the facilities expected to ramp up in the second half. A further 2.4 mn t facility at Varkala in Bihar is scheduled for commissioning during the period. Higher fuel and logistics costs remain a challenge, while the company has realised a cement price increase of about Rs. 10 per bag in October and is targeting operating costs of Rs. 4,250 per t for the full year.
