Density of Coarse Aggregate
Aggregate which occupy nearly 80 to 85 % volume of concrete are most important part of the concrete or RCC. However, it is well recognize that physical, chemical and thermal properties of aggregate substantially influence the properties and performance of concrete. Proper selection and grading of aggregates are important consideration, both economically as well as technically.

Aggregate of concrete

The normal weight of stone aggregate in loose state is= 1400 to 1600 kg per cum, but for illustration an average value 1500 kg per cum is considered.
