Aggregate for ready-mix concrete, by simply replacing from 10 to 45% of the natural aggregates in the concrete mix with a blend of cement, sand and water. Some concept buildings are showing the progress of this field. Because the RCA contains cement it, the ratios of the mix have to be adjusted to achieve desired structural requirements such as workability, strength and water absorption.

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 and

Key points. • ‘Aggregate’ is a term for any particulate material. It includes gravel, crushed stone, sand, slag, recycled concrete and geosynthetic aggregates. Aggregate may be natural, manufactured or recycled. • Aggregates make up some 60 -80% of the concrete mix. They provide compressive strength and bulk to concrete.

Concrete mixtures containing rough textured or crushed aggregate would show somewhat higher strength at early ages than corresponding concrete containing smooth or naturally weathered aggregate of similar mineralogy. A stronger physical bond between the aggregate and the hydrated cement paste is assumed to be responsible for this. At later ages the influence of the surface texture of aggregate
