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

Application of Foundry Waste Sand In Manufacture of Concrete properties of fresh & hardened concrete containing ferrous & non-ferrous foundry waste sand as fine aggregate replacement. Fine aggregates were replaced with four percentages of foundry sand. The percentages of replacements were 0, 10, 20, & 30% by weight of fine aggregate & tests
Manufactured aggregates play only a very small role in the supply of aggregates to the UK market. Total aggregate supply for the UK (excluding N. Ireland) for 2006 is 274 million tonnes (Mt). Of this demand the majority is supplied by natural materials from crushed rock and land-won or marine dredged sand and gravel (204 Mt).
