Manufactured sand gaining traction

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.

The Department of Civil Engineering at Dhanekula Institute of Engineering & Technology, Ganguru, organised an industrial interaction programme under the Adani FutureX Programme on Thursday. The programme focused on strengthening engagement between the institute and the cement industry while giving students greater exposure to professional practices.

Yedukondalu, technical head for Andhra Pradesh and Telangana at Adani Cement, delivered a technical lecture on concrete as a man-made material. The session covered the importance of concrete in construction, its properties and applications, and its significance in modern infrastructure development.

The lecture also addressed the role of quality cement and suitable concrete technology in supporting durable and sustainable construction. The discussion connected classroom learning with the technical considerations involved in infrastructure projects and construction practices.

A key part of the programme was the signing of a memorandum of understanding (MoU) between the Department of Civil Engineering and Adani Cement under the Adani FutureX Partnership Agreement. The agreement is intended to strengthen industry-academia collaboration through opportunities for student internships and industrial visits.

The initiative is expected to provide students with practical exposure, improve their understanding of industrial practices and help bridge the gap between theoretical knowledge and real-world applications. Dhanekula Institute Chairman Dhanekula Ravindranath Tagore, Secretary Dhanekula Venkata Bhavani Prasad and Director DKRK Ravi Prasad supported the initiative, with the institute leadership highlighting the importance of industry-institution interaction in enhancing students’ technical employability.

JK Lakshmi Cement has laid the foundation stone for Project Kamakshi, its first integrated cement manufacturing facility in Assam, marking the company’s entry into Northeast India. The groundbreaking ceremony took place at Umrangso village in Dima Hasao district in the presence of Assam Chief Minister Himanta Biswa Sarma.

The project involves an investment of Rs. 110 bn, including the mining lease. It will have annual cement production capacity of 2.5 mn t and a 1 mn t clinkerisation unit, with completion scheduled for FY2029.

The facility is expected to create more than 2,000 jobs and will primarily serve the growing Northeast market. It will also include dedicated railway sidings for transporting raw materials and finished cement, supporting supply chain reliability and regional distribution.

Chairperson and Managing Director Vinita Singhania said the project represented the beginning of a long-term relationship with Assam and the wider Northeast. She said the plant would help provide locally produced cement, employment and dependable supplies as the region’s infrastructure development accelerated, while enabling the company to grow alongside the communities it serves.

The investment supports JK Lakshmi Cement’s strategy of expanding into high-growth markets beyond its established presence in Northern, Western and Eastern India. The company expects the project to contribute to regional economic development and infrastructure growth while pursuing its long-term objective of achieving net-zero emissions by 2047.
