Umesh Soni, Corporate Head, Customer Support Services, Ambuja Cement, speaks on the services offered by the ‘Concrete Futures Laboratory’ (CFL) that his company has developed for its customers.

Which is the most popular service for the construction fraternity offered through CFL? Please explain quoting some numbers.
Concrete mix design is the most preferred service among the construction fraternity. Through CFL, we provide concrete mix design as per the performance need of the customer. In the first six months of 2016, we have provided 89 concrete mix designs through CFL.

Tell us about a few services which may not be very popular, but are offered only by CFL.
The service of analysing the fine aggregate in terms of particle shape and clay content is a unique test offered only by CFL.

Tell us about the Holcim Cone test. In what way will it help the site engineer?
Holcim Cone is an application-based testing methodology developed to assess the rheological and mechanical performance of concrete. In a simplified approach, Holcim Cone testing helps to assess the workability and strength development of a concrete by testing its mortar. This test is also helpful in understanding the compatibility of cement and chemical admixtures. It is useful to a site engineer for analysing the fresh concrete properties quickly with less volume of concrete in the laboratory and to derive the concrete mix proportioning.

How has been the response of your customers to the services you offer for high performance concrete and self-compacting concrete? Will customers increasingly ask for more such services in the future?
There is very encouraging response from our customers since usage of high performance concrete and self-compacting concrete is increasing day by day in metros and megacities. Both these advanced concretes are becoming inevitable for high-rise constructions. Since both concretes are special concretes involving more number of concrete materials and there is great influence of material properties on the concrete performance, customers are seeking help for developing mix design and conducting the trials in the laboratory. CFL is the enabler for developing such advanced concretes. As it is becoming more popular, more customers will ask for such services.

Do you produce slag cement in any of your plants; is the user of slag cement expecting some different service?
At present, we do not produce slag cement in any of our plants. There will not be any difference in services in case of using slag cement. The user mainly requires the services of testing the fresh and hardened properties of concrete as well as concrete mix design, which is applicable for users of slag cement also.

Is the expectation of service different between a trade customer and a non-trade customer?
There is difference in the expectation of service from trade and non-trade customers, mainly in terms of grade of concrete as well as performance of concrete at different stages. We have developed services and solutions for both the segments separately. For example, for the trade segment, we have developed the scientific tool of concrete mix proportioning as well as modular curing solution. The non-trade customers are mainly looking for a customised concrete solution as per their performance requirements as well as for analysing the concrete materials.

An endeavour from Ambuja Cement, the ?Concrete Futures Laboratory (CFL)? is shaped to be one of the most innovative and exhaustive places for testing, learning and experiencing cement and concrete for architects, engineers and the construction community. Ambuja has a network of eight CFLs across India, set up in line with the requirements of ISO/IEC 17025:2005. All these centres possess NABL accreditation.

Andhra Pradesh Education and IT Minister Nara Lokesh on Wednesday laid the foundation stone for the Line-2 expansion of Dalmia Bharat Cement at Chinnakomerla village in Mylavaram Mandal in Kadapa district. The project carries an investment of Rs 31 billion (bn) and is slated for completion by the third quarter of the financial year 2028. The expansion is intended to boost industrial growth and employment generation across the Rayalaseema region.

Once commissioned, the Kadapa facility will become Dalmia Bharat’s largest integrated cement manufacturing ecosystem in southern India, creating over 1,000 direct and indirect jobs and opening new business avenues for regional micro, small and medium enterprises and transport operators. Lokesh said the expansion signalled growing corporate confidence in the state and reflected the practical ease of doing business that secured repeat investment.

He placed the project within the government’s wider economic targets and recalled the Yuvagalam padayatra commitment to generate two million (mn) jobs within five years, noting that the state would cultivate talent while industry created opportunities. Lokesh highlighted Andhra Pradesh’s competitive pursuit of major manufacturing accounts, mentioning past successes and a personal initiative to engage global investors when persuading them to anchor expansion in the state.

The plant will leverage Kadapa’s abundant limestone reserves to scale production and sustainability. Clinker capacity is planned to rise from two point five million tonnes per annum (mn tpa) to six point one mn tpa, while overall cement output will increase from three point six mn tpa to nine point six mn tpa. The unit is designed to operate on over eighty per cent renewable energy and deploy waste heat recovery, zero liquid discharge, water recycling and advanced AI systems to optimise efficiency. Industries Minister TG Bharat, BC Welfare Minister S. Savitha and Jammalamadugu MLA C. Adinarayana Reddy attended the ceremony.

Cement Prices to Stay Flat in Q2 FY27 as Costs Squeeze Margins

HDFC Securities warns monsoon slowdown and higher fuel costs

Published

HDFC Securities has said the cement industry is unlikely to register a sequential increase in prices in Q2 FY27 as monsoon-related demand moderation coincides with rising fuel and packaging costs that will squeeze margins. The brokerage observed that price gains remained modest, with increases of two to three per cent quarter-on-quarter across regions, and noted subdued offtake in May with improvement in June as a delayed monsoon supported construction activity. The brokerage added that modest pricing gains so far have been insufficient to offset the input cost escalation.

The report stated that input cost pressures intensified in Q1 FY27 owing to the West Asia conflict, which pushed up coal and pet coke prices and is expected to keep fuel costs elevated, with a likely peak in Q2 FY27. It assessed that total variable costs, including packing, could rise by around Rs 150 per t quarter-on-quarter and that lower offtake and seasonal operating deleverage could further raise operating expenditure by about Rs 50 per t quarter-on-quarter.

Overall, cement prices were estimated to remain flat in Q2 FY27 as monsoon-led demand weakness offsets limited upside in realisation, and rising fuel costs alongside seasonal deleverage were expected to compress industry margins by over Rs 100 per t quarter-on-quarter to below Rs 880 per t. The brokerage indicated that the combined impact of energy inflation and higher packing expenditure would be the principal drivers of margin contraction in the near term. HDFC Securities projected a recovery in margins in H2 FY27 should the West Asia turmoil subside and energy and packing costs cool off.

The brokerage expressed optimism on long-term demand fundamentals and said improving realisation together with an anticipated cost cool-off should support a margin rebound from H2 FY27 onward, underpinning favourable industry prospects over the medium term. Its outlook rests on monsoon normalisation and a decline in imported fuel prices in the second half of the fiscal year.
