Abstract. Both coarse aggregates and fine aggregates are the main constituents of concrete because they not only give the body to the concrete, it also have a significant effect on the fresh concrete based on aggregate's shape, size, texture, grading and crushing type.

As a thumb rule, the minimum compressive strength of a cement mortar must achieve 2/3rd (66%) of its mix design strength after 7 days. In case it does not achieve the minimum 2/3rd strength of the mix design after 7 days, one can conclude the concrete has failed and hence will not achieve the required strength as designed.
