What is the effect of flyash on bricks

Question

Accepted Answer

Flyash can improve the strength and durability of bricks by reducing water absorption and increasing resistance to chemical attacks.

Flyash is a byproduct of coal combustion and contains silica, alumina, and iron oxide which can react with lime in bricks to form calcium silicate hydrate, enhancing strength.
Incorporating flyash in brick production can reduce the amount of clay needed, making the bricks more sustainable and environmentally friendly.
Flyash can also reduce the weight of bricks, making them easier to handle and transport.
Bricks made with flyash have lower water absorption rates, leading to improved durability and resistance to freeze-thaw cycles.
The use of flyash in bricks can also help in reducing greenhouse gas emissions by diverting a waste product from landfills.
