showed that all the grout types reached the expected compressive strength of 2000 psi at 28 days, except for grout type 4, where fly ash replacement was 65%, and ground granulated blastfurnace slag 0% (35% of cement in the mix).
Strength of cement is defined in three ways: Compressive, Tensile flexural. Usually compressive test is carried out. Strength of cementsand paste can be affected by number of items including: watercement ratio, cementsand ratio, type and grading of sand, manner of mixing, size and shape of specimen, curing conditions, rate of loading and .
