The state government should device a mechanism to ensure the quality of M-sand distributed in the state. Low quality material not only gives a low quality precast but also affects the durability of concrete, says Joseph Jacob, Director, POABS Group

Manufactured sand or M-sand is gaining popularity among customers as many states have banned the use of river sand. What were the challenges?

M-sand is a registered trademark of POABS. This concept was launched in 2002, in Kerala. The company had some crusher plants and was looking at ways to use crusher dust/ crusher sand—the byproduct from the plants, in concrete. However, there were challenges like the shape of the dust and presence of varied percentages of microcytes. Use of these type of concrete dust can cause durability and load bearing (strength) issues. So, these were used as landfill or dumped. However, with the price of river sand moving upward, and the restriction on extraction of river sand led us to innovate and convert the crusher sand to usable manufactured sand. With the support of College of Engineering Trivandrum, we have established the first M-sand plant in Thiruvananthapuram. Till then the industry was dependent on river sand that is cylindrical in shape which blends well in the concrete mix.

With new concepts come new technologies. Can you describe the technologies being used in manufacturing sand?

The first plant was set up with wet technology. Crushed particles are first passed through a vertical shaft and then through a wet process. While the river sand is cylindrical in shape, crushed sand it is cubical. The cubical shape adds more strength to the concrete. The only challenge now remaining is the removal of microcytes. The Indian Bureau of standards permits use of 150 microns not exceeding 10 percent and 75 microns not exceeding 2 percent in the concrete mixture. When crush sand is washed, in the process we lose 300 and 600 microns. So, challenge was to retain the 300 and 600 microns and remove the 150 and 75 microns from the same lot.

What is your market in m-sand?

Till FY2009 -10, we held 50 percent market share in Kerala. Increase in number of palmers and import of m-sand from the neighboring states has impacted our market share. Also, there is no mechanism in Kerala to check the quality of m-sand distributed in the state. Cheap quality material is easily available in the market at lower rates, and that is chief competition.

What are the regulatory challenges?

There is no quality check for the m-sand coming from different places. The QC is possible only if it is produced locally. If the material is transported from other states, implementing QC check is very difficult. Once such low-grade m-sand is used in concrete, there are ways to check the strength but difficult to gauge durability.

Which segment is your major consumer RMC or retail? And what are your expansion plans?

We have our own RMC business arm. We do cater to both—RMC and the retailers. The demand for m-sand is growing is rising from states where local governments have imposed restrictions on river sand. Most South Indian and West Indian states have moved to m-sand now. Considering the opportunities, we are definitely looking at expanding. We are in advanced talks with some states, though it is too early to divulge details. Currently we operate only in Kerala and Tamil Nadu.

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.
