Manufactured sand is fulfilling 50 per cent of the total demand for sand being used in concrete mixtures in the country. Sanjay Nikam, CEO and Principal Business Consultant with Suru09 Business Services, feels that with the shortfall in river sand, the demand for m-sand will accelerate manifolds.
Can you explain the different types of sand?
There are different kinds of sands. For instance, the crush stone sand is a fine aggregate produced by crushing hard stone. The crush grail sand is a fine aggregate produced by crushing natural gravel; mix sand is a mix of the two. Then there is manufactured sand which is produced from resources other than natural resources
What are the key challenges faced by the manufactured sand industry?
The industry is facing many challenges. First and foremost is the challenge being the paucity of a uniform regulation pan India. Presently, different state governments have different licensing provisions, norms for royalty payments, sand dredging, etc. This results in disparity, cost undercutting and the easy availability of low-grade sand at cheaper rates in the market. Secondly, the crush quarry are smaller in size (25-50 acres) as compared to a cement mining area that can range beyond 1000 acres. That means one cannot have bigger area of operations. The output from these crusher plants range from 25,000 to 40,000 tons a month. Thirdly, logistics and local issues play a key role in this industry essentially because we are located very close to the city.
What is the ratio of aggregates and m-sand used in concrete?
In concrete, for every ton of cement used, the ration of aggregates used is 7 to 10 times higher. Of this, 50 percent is sand. For e.g., if the requirement of sand is 15,000 million tons, manufactured sand constitutes 50 percent.
Manufactured sand consumption has picked up from 2008, and the uptake was faster because of a decline in the volume of supplied river sand. While river sand registered a negative CAGR (-2 percent), the manufactured sand is registering a CAGR of 35 percent for the past couple of years. Fine aggregate offers better benefit and value than the coarse aggregator.
What kind of investments or expansion plans are you witnessing in the m-sand segment?
Realizing the poetical of the segment, there is a steady flow of investments. The number of players in m-sand segment has increased which encourages healthy competition. Also, there are players who are looking at aggregators and m-sand as apart of portfolio diversification. Globally if you take the leading cement players, they are present in the cement, RMC and aggregator segments. The trend will soon follow in India.
You mentioned changing global trends in the usage of m-sand. Can you elaborate further?
Globally, Japan is the first country to develop technology in the engineered sand segment because of the shortage of river sand. In Asia, China took the first move in the same direction because of the shortfall faced. Now that India also has challenges with river sand, the country has adopted Japanese technology to manufacture m- sand in the country. The adoption of m-sand in Europe and US is comparatively lower as governments in these continents have not imposed restriction on river sand dredging.
