Compressive strength of concrete – cube test procedure

The compressive strength of M20 grade concrete varies between 17 and 23 N/mm2 (i.e. between 170 kg/cm^2 and 230 kg/cm^2) after 28 days curing. This means that the concrete can withstand a compressive load of 170 to 230 kg/cm² before it fails.. In compressive strength test of concrete cube the push force applied on the both faces of concrete …

Definition of crushing strength

It is measured by applying graduated pressure to a cube, 1 in (2.54 cm) square, of the rock tested. A crushing strength of 4,000 lb means that a cubic inch of the rock withstands pressure to 4,000 lb (111 kg/cm 3) before crushing. The crushing strength is greater with shorter prisms and less with longer prisms. Ref: Fay ii.
