Effect of Aggregates On Strength Of Concrete

Mar 16, 2012  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.
