Primary Capability: These blocks don't cause any additional heap on the plan of designs because of its similar thickness and consequently give better protection from quakes and other normal cataclysms. The compressive strength of Fly Ash and lime blocks is normal 1305 psi (9.00 N/mm2) (as against 507 psi [3.50 N/mm2] for carefully assembled earth blocks). The blocks have high compressive strength which dispenses with breakages/wastages during transport and taking care of. At the point when a construction is framed utilizing Fly Ash blocks the chance of breaking of mortar is decreased because of lower thickness of joints and mortar and essential material of the blocks, which is more viable with concrete mortar.
