### Compressive Strength of Cement | The Construction Civil

Compressive Strength of Cement. This test is carried out to determine the compressive strength of cement. 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.
