Our Indian Origin Fly Ash is a quality assured dry Fly Ash (Full compliance to ASTM C618 Class-F / Class-C, BS 3892 Part-1, BS EN 450 and IS 3812) suitable to use in all concrete to improve the strength, stability and long-term durability of concrete. Under normal conditions, our Fly Ash is used to replace 15-35% of Portland cement by weight. Fly Ash can also be added without cement reduction to achieve desired mix characteristics.

Tests made in accordance with ASTM C 441 and ASTM C 1012 have shown that the use of our Fly Ash significantly reduces the potential for damage due to alkali-aggregate reactivity and sulfate attack. Depending on the quantity of ash used, the use of our Fly Ash consistently provides a 10% or greater reduction in the amount of water required for a given workability. This translates directly into increased strength and durability, reduced potential for shrinkage, reduced segregation, and most importantly, lower permeability.
