Concrete Aggregates

Crushing strength, impact value abrasion resistance, and elastic modulus of aggregate are interrelated properties that are greatly influenced by porosity. Aggregates from natural sources that are commonly used for making normalweight concrete, are generally dense and strong; therefore they are seldom a limiting factor to strength and elastic properties of concrete.

Influence of Crushed Coarse Aggregates on Properties of ...

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. Moreover it is proved that aggregate's types has the severe effect on physicmechanical properties of concrete as aggregate covered ...
