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 deterioration of concrete.

1997-5-1 The main objective of this research is to investigate the potential use of reclaimed asphalt pavement (RAP) as an aggregate in portland cement concrete (PCC). RAP aggregate finer than number 4 (4.75 mm) sieve was treated as fine materials while those particles passing 3/4 inch (19.05 mm) and retained on number 4 sieve were treated as coarse aggregate.

Laboratory investigation of portland cement

2005-10-1 In concrete made with RAP, asphalt forms a thin film at the interface of cement mortar and aggregate, which can be used to arrest crack propagation, Fig. 1. Thus, crack develops around rather than go through aggregate particle, during which more energy can be dissipated.
