Permissible compressive strength of M 300 concrete grade is A 100 kg/cm2 B 150 kg/cm2 C ⇒ To ensure constant moisture content in aggregates area of each aggregate pile should be large height of each aggregate pile should not exceed 1 50 m aggregate pile should be left for 24 hours before aggregates are used all the above ⇒ Workability improved by adding air-entraining agent and 30 concrete As for grade 20 quarry dust concrete records a lower compressive strength than river sand concrete As generated quarry dust can be recommended to be used as a fine aggregate in structural concrete for higher grades REFERENCES BS 882 1992 Specification for aggregates in concrete from natural sources for concrete

The Effect of Aggregate Properties on Concrete Concrete is a mixture of cementious material aggregate and water Aggregate is commonly considered inert filler which accounts for 60 to 80 percent of the volume and 70 to 85 percent of the weight of concrete Although aggregate is considered inert filler it is a necessary component that defines the concrete's thermal and elastic properties

## Recycled Concrete Aggregates A Review

After demolition of old roads and buildings the removed concrete is often considered worthless and disposed of as demolition waste By collecting the used concrete and breaking it up recycled concrete aggregate (RCA) is created (Fig 1) This paper focuses on coarse RCA which is the coarse aggregate from the original concrete that is created after the mortar is separated from the rock which
