### Effect of Aggregates On Strength Of Concrete

Aggregates shape and size has a strong influence on properties of concrete. Rough surface textured particles increase the compressive strength of concrete up to 20-30%, instead of using natural gravels that is obtained from river beds. Rough surface have pores which have ability to form bond or create resistance against the applied load.

2014-1-8 Walker and Bloem (1960) and Bloem and Gaynor (1963) concluded that an increase in aggregate size results in a decrease in the compressive strength of concrete. Cook (1989) showed that, for compressive strengths in excess of 69 MPa (10,000 psi), smaller sized coarse aggregate produces higher strengths for a given water-to-cement ratio.
