Those rocks are been used in the construction for levelling the areas and in the foundation fillings. The compressive strength is been compared in the study, the replacement on the percentages (25, 50 and 75%) at 7, 14 and 28 days, respectively. Then, the compressive strength is tested and tabulated.
