Aggregates Portland Cement Association

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.

Aggregate for Concrete Cement & Concrete in India

2020-7-26  Concrete produced with flaky and elongated aggregates will tend to segregate and require higher quantities of cement and sand. Flaky and Elongated particles produce very poor porous concrete, reducing the strength and durability of concrete. Flaky particles should not be more than 10-15% of the weight of coarse aggregates.
