Coarse Aggregate Properties

Crushed rock creates a much better bond between the paste and the aggregate than a gravel does. However, the aggregate-mortar bond may be more important in flexure tests than in compression tests. The mineral makeup of the aggregate also influences the modulus of elasticity of concrete.
