Construction aggregate, or simply aggregate, is a broad category of coarse- to medium-grained particulate material used in construction, including sand, gravel, crushed stone, slag, recycled concrete and geosynthetic aggregates. Aggregates are the most mined materials in the world. Aggregates are a component of composite materials such as concrete and asphalt concrete; the aggregate serves as reinforcement to add strength to the overall composite material. Due to the relatively high hydraulic con
Aggregate, in building and construction, material used for mixing with cement, bitumen, lime, gypsum, or other adhesive to form concrete or mortar. The aggregate gives volume, stability, resistance to wear or erosion, and other desired physical properties to the finished product.
Introduction (1): What are Aggregates? Aggregates are crystalline or granular rocks that are extracted for use in the construction industry. These can be either primary aggregates (extracted from the ground in quarries) or secondary aggregates (recycled from construction waste). Aggregates are an essential material in building and repairing things such as roads, railways and homes.
Construction aggregate is coarse to medium-grained particulate material that is useful for construction-work. It is often referred to as simply aggregate as well. This includes material like sand, gravel, crushed stone, etc.
