compressive strength of concrete hollow blocks

ASTM SPECIFICATIONS FOR CONCRETE MASONRY UNITS

Minimum compressive strength requirements are 4,500 psi (31 MPa) for an individual unit and 5,500 psi (37.9 MPa) for an average of three The compressive strength of a hollow concrete block is mainly determined by its composition, especially the binder content in the mixture, compaction The strength of hollow concrete block walls, reinforced
