Aggregates Portland Cement Association

Aggregates are inert granular materials such as sand, gravel, or crushed stone that, along with water and portland cement, are an essential ingredient in concrete. For a good concrete mix, aggregates need to be clean, hard, strong particles free of absorbed chemicals or coatings of clay and other fine materials that could cause the

Aggregate Concrete an overview ScienceDirect Topics

the increase in cement content of recycled aggregate concrete compared to natural aggregate concrete is small, up to a few percent at most; this is possible in RAC with 100% coarse aggregate replacement if the RCA is of good quality, and certainly achievable in RAC with 50% coarse aggregate replacement.

Concrete Wikipedia

Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. In the past limebased cement binders were often used, such as lime putty, but sometimes with other hydraulic cements, such as a calcium aluminate cement or with Portland cement to form Portland cement concrete

What's the Difference Between Cement and Concrete?

The aggregates are sand and gravel or crushed stone; the paste is water and portland cement. Concrete gets stronger as it gets older. Portland cement is not a brand name, but the generic term for the type of cement used in virtually all concrete, just as stainless is a type of steel and sterling a type of silver.
