Aggregate is an aggregation of non-metallic minerals to form a solid particle. Aggregates can be natural or artificial. Natural aggregates are formed by weathering, disintegration on parent rocks. Pebbles, sand, gravel, are examples of natural aggregates. Natural aggregates are round, flaky, and platy in shape.
