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.

EFFECTS OF AGGREGATE TYPE, SIZE, AND CONTENT ON
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.

Effect of Aggregates on the Properties of Concrete
2022-8-11 The shape of aggregate affects the workability of the concrete to a great extent, hence its strength and durability. Shape affects compressive strength by 22% and flexure strength by 30%. Flaky Particle: A particle is said to be flaky, if its least dimension (thickness) is less than 0.6 times the mean sieve size.
