NTPC to set up nano concrete plant

01 Jan 2023 CW Team

NTPC Simhadri will develop a plant that produces nano concrete aggregate, at an estimated cost of Rs 500 million.

The general manager of ash management of NTPC Sanjeev Kumar Saxena said, "The disaster recovery planning is prepared and construction will commence at the end of the first quarter of 2023. We will develop ash-based building products which include fly ash bricks, lightweight aggregate, geopolymer coarse aggregate, and interlocking paver tiles."

"With twin objectives of helping sustainable development and judicious use of fly ash, NTPC is exploring all possible avenues of using fly ash, which can be done by replacing cement, road building, low lying area and mine filling. Since the focus is on topsoil protection, it can be achieved by using fly ash as an alternative. Nearly 300 million tonnes of bricks and 300 million tonnes of cement will be used. Around 100 million tonne of sand has come from rivers and topsoil, which should be used for agriculture, not for making bricks," he said.

"To convert fly ash into aggregate sand, up to 35% of OPC (original portland cement) can be replaced by fly ash. This can also bring down the cost sustainability besides greater long-term strength, durability and permeability. Fly ash is also useful in landfilling for developing wastelands and low-lying areas in agriculture, horticulture and forestry. It is also an ideal material to fill underground mines, reclamation of abandoned and open cast mines," he stated.
