Compression tests on hollow sandcrete blocks are conventionally confined to the as-cast face neglecting the other two orthogonal faces. 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.

This paper discusses the results of a systematic experimental investigation on 306 stretcher bonded concrete hollow block masonry prisms under axial compression for the influences of block-mortar strength combinations, block geometry, height to thickness ratio (h/t) of block, mortar bedding, and thickness of mortar joint.

the compressive strength of blocks varies from about 2- 15kN/mm2. But this value depends on the target compressive But this value depends on the target compressive

hollow concrete blocks manufacturing, demonstrated that the compressive strength of the samples was lower than the actual block strength, due to the pressure and curing inherent to the production process (Frasson Junior 2000).

According to the Code this would require a block compressive strength of 1900 psi. Recently on projects, some designers are now specifying a higher f’m, i.e., 2000 psi, 2500 psi and 3000 psi with Type S mortar. According to the Code this would require a block compressive strength of 2800 psi, 3750 psi and 4800 psi, respectively.
