Fly Ash Building ProductsFly Ash Hollow Blocks
Hollow concrete blocks to IS 2185 Part 1 - fast to lay, light on the structure, better insulating than solid units.
One hollow block replaces several bricks, so walls go up faster with less mortar. The voids cut the dead load on the frame and improve thermal performance, and they give services somewhere to run without chasing the wall.
