Aggregates - Portland Cement Association

Aggregates. 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 is usually described as either coarse aggregate (retained 4.75 mm) or fine aggregate (passing 4.75 mm). Aggregates generally make up about 95 percent of the total mass of hot-mix asphalt mixtures and 80 percent by mass of concrete - aggregate properties are, therefore, critical for quality hot-mix asphalt or concrete.
