Testing of Concrete Masonry Blocks for Compressive Standard Specification for Hollow Brick Hollow Masonry

Compressive strength of concrete Blocks or concrete masonry units are required to know the suitability of these in construction works for various purpos Concrete masonry blocks are generally made of cement aggregate and waterHollow brick require greater shell and web thicknesses and higher minimum compressive strength than structural clay tile but permit greater void area and lesser distance from exposed edge to core hole than solid brick Therefore environmental and structural performance may be different in elements constructed of hollow brick from those constructed of structural clay tile or solid brick
