### How to Determine the Compressive Strength of Cement Mortar

Jun 08, 2012 Mortar is a mixture of cement and sand in a specified ratio on which the strength of the mortar depends. If the mortar is weak then also its compressive strength is very low but if the mortar is a strong one then its compressive strength is also very high.

Test Procedure for compressive strength of cement: (i) The mortar of cement and sand is prepared. The proportion is 1:3 which means that (X) gm of cement is mixed with 3(X) gm of sand. (ii) The water is added to the mortar. The water cement ratio is kept as 0.4 which means that (X) gm of water is added to dry mortar.

Jun 04, 2012 Importance: Cement is usually subjected to compressive stresses when used in the form of concrete or mortar. The most comprehensive test for cement or for a mixture of it with sand is done by determining its crushing strength.Unfortunately, it requires a very costly machine and, therefore, the usual practice is to use the tensile test instead which can be carried out very cheaply.
