  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.

  Why We Test Concrete Compressive Strength after 28 Days?

  The rate of gain of concrete compressive strength in higher during the first 28 days of casting and then it slows down. The table below shows the compressive strength gained by concrete after 1, 3, 7, 14 and 28 days with respect to the grade of concrete we use.
