Aggregates

Aggregates are inert granular materials such as sand, gravel, or crushed stone that, along with water and Portland cement, form the necessary ingredients in concrete. Aggregates need to be clean, hard, strong particles free of absorbed chemicals or coatings of fine materials that could cause the deterioration of concrete. Aggregates account for
