When we estimate the concrete quantity, the aggregates will occupy 70 to 75% of the volume.. The classification of aggregates depends on the grain size, density, shape, and geographical origin. So the properties of aggregates will differ based on the classification, and it may influence the mix of the concrete and strength.
