How to Choose Quality Coarse Aggregate for Concrete ...

Coarse aggregate should contain various fraction sizes to ensure adequate compaction of particles, hence resulting in increased density and reduced voids in 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
