Sand is a granular aggregate composed of fine rock and mineral particles. It is a vital construction aggregate essential in the manufacture of concrete. The composition and colour of sand varies, depending on the local rock sources and conditions. The most common constituent of sand in inland continental settings is silica.
Aggregates. Aggregates are inert granular materials such as sand, gravel, or crushed stone that, along with water and portland cement, are an essential ingredient in concrete. For a good concrete mix, aggregates need to be clean, hard, strong particles free of absorbed chemicals or coatings of clay and other fine materials that could cause the ...
