Density of Cement, Sand and Aggregate, Bulk Density of Aggregate

Crushed stone dust or natural sand is the fine aggregate chiefly utilised in the concrete mix. Sand may be collected from the river, sea, lake or pit. Still, when used in the concrete mix, it should be adequately cleaned and tested to determine that the total percentage of silt, salts, clay and other such organic stuff does not pass the defined limit.

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 deterioration of concrete.
