Manufactured sand is fulfilling 50 per cent of the total demand for sand being used in concrete mixtures in the country.

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.

PROMECON introduces infrared-based tertiary air measurement system for cement kilns

The new solution promisescontinuous, real-time tertiary air flow measurement in cement plant operations.

PROMECON GmbH has launched the McON IR Compact, an infrared-based measuring system designed to deliver continuous, real-time tertiary air flow measurement in cement plant operations. The system addresses the longstanding process control challenge of accurate tertiary air monitoring under extreme kiln conditions. It uses patented infrared time-of-flight measurement technology that operates without calibration or maintenance intervention.

Precise tertiary air measurement is a critical requirement for stable rotary kiln operation. The McON IR Compact is engineered to function reliably at temperatures up to 1,200°C and in the presence of abrasive clinker dust. Its vector-based digital measurement architecture ensures that readings remain unaffected by swirl, dust deposits or drift. Due to these conditions conventional measurement systems in pyroprocess environments are often compromised.

The system is fully non-intrusive and requires no K-factors, recalibration or periodic readjustment, enabling years of uninterrupted operation. This design directly supports plant availability and reduces the maintenance overhead typically associated with process instrumentation in high-temperature zones.

PROMECON has deployed the McON IR Compact at multiple cement facilities, including Warta Cement in Poland. Plant operators report that the system has aided in identifying blockages, optimising purging cycles for gas burners, and supplying accurate flow data for AI-based process optimisation programmes. The practical outcomes include more stable kiln operation, improved process control, and earlier detection of process disturbances.

On the energy side, real-time tertiary air data enables reduction in induced draft fan load and helps flatten process oscillations across the pyroprocess. This translates to lower fuel and energy consumption, fewer unplanned shutdowns, and a measurable reduction in NOx peaks. This directly reflects on the downstream cost implications for plants operating SCR or SNCR systems for emissions compliance.

Railways Boost Cement Movement by 170 Per Cent and Eye Fly Ash

New container wagons cut costs and speed turnaround

Indian Railways has recorded a 170 per cent rise in cement movement in the last four months after reforms launched in November to promote rail based bulk cement logistics. The Union Railway Minister, Ashwini Vaishnaw, reviewed the container sector reforms and their implementation and described the shift as improving plant to market efficiency. The reforms introduced customised bulk cement tank containers and a bulk cement terminal policy to support multimodal handling and door to door solutions.

The new system has simplified loading and unloading by enabling mechanised operations and by reducing package losses compared with bagged cement transport. Since cement can move directly from manufacturing centres to consumption centres in standardised tank containers compatible with Ready Mix Concrete machines, two stages of handling have been eliminated and material loss has been reduced. The standard shape of the containers facilitates faster turnaround and lowers logistics costs for suppliers and builders.

The improved freight turnaround is helping to lower the delivered cost of cement, which can ease pressure on housing costs for the poor and middle class and support affordable construction. The reform is said to be environment friendly as dust generation during material transfer has fallen and fuel consumption and emissions have reduced due to modal shift from road to rail. The Make in India tank containers are designed for seamless movement between train and trailer and to enable efficient door to door movement while cutting congestion on roads.

Building on the cement reforms, officials were urged to tap the fly ash transportation market to convert industrial waste into national wealth. The minister noted that nearly 300 million metric tonnes (mn t) of fly ash is produced in the country while only about 13 million t is transported by rail and asked officials to substantially increase Railways share to serve brick kilns, cement industries and construction sites. Wider utilisation of fly ash should reduce pollution, promote recycling and lower construction material costs while strengthening sustainable freight movement across infrastructure sectors.
