Aggregates Aggregates generally occupy 65- 80% of a concrete’s volume. Aggregates are inert fillers floating in the cement paste matrix for concretes of low strength. The strength of aggregates do not contribute to the strength of concrete for low strength concrete. The characteristics of aggregates impact performance of fresh and hardened

Greater is the aggregate crushing value, softer is the aggregate sample and vice versa. This is suggestive of the fact that the resistance of aggregates to crushing is less. Therefore, the strength of such a sample is also less. Aggregates having relatively less ACV can be used in wearing surfaces of pavements. 2)Hardness

Katz (2003) investigated the compressive strength of concrete which was crushed to serve as a source of aggregate for new concretes. In the investigation it can be noted that as smaller is the crushed aggregate as higher is the water absorption. Coarse aggregates among 9.54 to 25 mm had absorption of 3.3% in 28 days. Medium aggregates (2.36 to
