More2018-5-1 However, strength of one type of concrete to another vary only in the range 2.5–7.4% indicating that type of aggregate has not shown much impact on compressive strength of Normal Strength Concrete. It is due to the fact that the aggregate is not the strength limiting factor as it is stronger than cement matrix and transition zone.

Moreconcrete and established that aggregate type has effect on the compressive strength of normal concrete, and that concrete made from crushed quartzite would give the highest compressive strength at all ages but concrete made with granite as coarse aggregate would give the least strength. On the contrary, Aginam et al. (2013) found that
