Best Types of Aggregates for Concrete | Construction

In concrete, aggregate is the granular substance that holds the mixture together in its solid form. Aggregates vary in size and shape, and they can be as finely ground as sand or as coarse as gravel. When mixed with water and cement, these compounds form concrete. Aggregates make up between 60-75% of the volume of the final mixed concrete.
