The Load Carrying Capacity of Hollow Sandcrete Blocks

Compression tests on hollow sandcrete blocks are conventionally confined to the as-cast face neglecting the other two orthogonal fac Also uniaxial compressive strength of hollow sandcrete blocks is defined on the basis of the apparent area of the as-cast face The definition has made no distinction between hollow and solid sandcrete blocks...
