COMPRESSIVE STRENGTH OF CEMENT IS 4031 Part 6

compressive strength test of the cement

COMPRESSIVE STRENGTH OF CEMENT The compressive strength of the cement cubes is the maximum load applied to the cubes during the test divided by its cross-sectional area. The average of the three specimens at each specified age shall be calculated. This method covers the method of compressive strength test of cement motor cubes compacted by …
