SEML very strongly believes in environment conservation and preservation. SEML manufactures eco-friendly bricks mainly from the fly-ash generated from our captive power plant. The manufactured bricks facilitate substantial consumption of fly-ash, an environmental hazard.
Fly-ash bricks have good compressive strength, low water absorption, high density and low shrinkage value as compared to burnt clay bricks. Raw materials required for manufacturing of bricks are Flyash, lime gypsum and sand. The process of manufacturing fly ash bricks is based on the reaction of lime with silica of fly-ash to form calcium silcate hydrates (C-S-H) which binds the ingredients to form a brick.
The Company is putting up a new fully automated fly ash brick-manufacturing facility of 160,000 bricks per day, which is expected to be commissioned in first quarter of next financial year.
