The test for compressive strength is generally carried out by crushing cubes of hardened cement-sand mortar in a compression machine. The compressive strength of the cubes is determined by the highest stress applied to a cube specimen that causes it to fracture. The test equipment required for this purpose includes a compression machine, a mortar mixer, suitable moulds, a humidity cabinet, the

The compressive strength of cement mortar cubes or concrete is one of the most important and useful property. The compressive strength of cement mortars is determined in order to verify whether the cement conforms to Indian Standard (IS, or other standards like ASTM, BS etc.) specifications and whether it will be able to develop the concrete of required compressive strength.
