What is Asphalt Aggregate? (with pictures)

One component of asphalt aggregate is sand. Asphalt aggregate is usually produced in rock quarries that are located near most heavily populated areas. Depending on the geological makeup of the area, the aggregate is usually composed of granite, marble, limestone or some other bedrock-quality stone. In areas that don't have minable deposits of these types of stone, natural sand and gravel are often mined and used as aggregates.

Vermiculite Concrete

2015-4-22  Vermiculite Concrete Introduction Vermiculite concrete is a low density non-structural construction product. It is insulating (both thermally and acoustically) and intrinsically fire resistant. It is normally made simply by mixing exfoliated vermiculite as the aggregate, with cement and water, plus additives such as plasticisers if required.
