A good quality concrete is essentially a homogeneous mixture of cement, coarse and fine aggregates and water which consolidates into a hard mass due to chemical action between the cement and water. Each of the four constituents has a specific function. The coarser aggregate acts as a filler.

3 Aggregate Properties - IN.gov

Crushed aggregate have irregular, angular particles that tend to interlock when compacted or consolidated. The crushed stone or crushed gravel aggregate make the asphalt or concrete mix somewhat difficult to place. To improve the workability, many mixes contain both angular and round particles. The coarse aggregate particles are

Recycled Aggregate Concrete - SlideShare

Nov 15, 2014  The use of recycled aggregate has been found to be better than that of virgin aggregates for certain applications. For example, the physical properties of recycled aggregates make them ideally suited for road base and sub-base. This is because of their physical properties which means less cement is required making them suited for sub-base use.

Concrete - Wikipedia

Fine and coarse aggregates make up the bulk of a concrete mixture. Sand, natural gravel, and crushed stone are used mainly for this purpose. Recycled aggregates (from construction, demolition, and excavation waste) are increasingly used as partial replacements for natural aggregates, while a number of manufactured aggregates, including air-cooled blast furnace slag and bottom ash are also ...
