The strength of the final mortar is strongly dependent on the type of materials and the ratio of the components, and testing is required to determine the correct proportions for each application. ASTM C109 describes the methodology for testing the compression strength of mortars using cubes of material that are 2 inches on a side.

Strength of Cement - Building Research Institute (P) Ltd.

Strength of cement is the most important of all the cement properties. Grades mentioned in the cement bags as 53/43 grade OPC/PPC in fact represent the strength of the cement. 53 Grade OPC Cement simply means that 28-days compressive strength of the cement -mortar cubes prepared out of that cement in a standard manner will be of 53 MPa.

Evaluation of the relation between the compressive strength ...

The compressive strength of cement mortar is principally determined by two methods, either by cubes or by prisms. In the cube method, the compressive strength is evaluated by directly subjecting the cube specimens to compressive load, where as in the prism method, the standard mortar prism (4×4×16cm) is first broken to two halves by flexural test, and then each half prism is subjected to ...
