## How To Choose Quality Coarse Aggregate For Concrete ...

In the majority of concrete works, aggregate sizes of 20 mm or smaller are used. To ensure good coarse aggregate compaction and higher concrete density, it is recommended to mix 20 mm and 10 mm coarse aggregates in the ratio of 70:30 or 60:40. It is recommended to stack different aggregate sizes to use them efficiently.

## Exp 5 Bulk Density

During the concrete mix design, when the aggregate is to be batched by volume or by weight, then it becomes necessary to know the mass of the aggregates that will fill the container of unit volume. If we know the bulk density of the aggregate material then we can easily determine the mass required to fill a unit volume container.
