    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

    Concrete production is the process of mixing together the various ingredients—water, aggregate, cement, and any additives—to produce concrete. Concrete production is time-sensitive. Once the ingredients are mixed, workers must put the concrete in place before it hardens. In modern usage, most concrete production takes place in a large type of industrial facility called a concrete plant, or often a batch plant. In general usage, concrete plants come in two main types, ready mix plants and central mix plants. A re

    What are Aggregate in Construction Industry ? In the construction industry, aggregate are used as filler material in the production of concrete and mortar. Aggregate occupy around 70% to 80% of the volume of the concrete, reduce shrinkage effects and minimize costs. The coarse aggregate form the main matrix of concrete and the fine aggregates form the filler matrix between the coarse aggregate.
