Aggregate

What is an Aggregate?

Aggregate refers to a composite construction material consisting of sand, gravel, crushed stone, and other particulate matter. This mixture forms a crucial component in the production of concrete and mortar when combined with binding agents like cement. The specific composition of aggregate significantly influences the strength, durability, and workability of the final product.

More In-depth Definition of Aggregate

A collection of granular materials such as sand, gravel, crushed stone, or recycled concrete used in construction. These materials provide bulk, strength, and stability to concrete and asphalt. They are categorized into coarse (e.g., gravel) and fine (e.g., sand) types based on size. The selection, processing, and grading of these materials are crucial for achieving the desired strength, durability, and performance of the final construction product.

Example of an Aggregate
