Standard Size of Flyash Brick In India

Standard Size of lyash Brick In India is

Length*Width*Height = 230*110*75 MM.

Manufacturing Process of Flyash Bricks


Fly ash (60%),
Lime (10%),
Gypsum (5%) and,
Crusher Dust (15%) are manually feed into a pan mixer where water is added to the required proportion for homogeneous mixing. The proportion of raw material may vary depending upon quality of raw materials. After mixing, the mixture are allowed to belt conveyor through feed in to automatic brick making machine were the bricks are pressed automatically. Than the bricks are placed on wooden pallets and kept as it is for two days there after transported to open area where they are water cured for 10 -15 days. The bricks are sorted and tested before dispatch.
