HOW FINE AGGREGATES AFEECTS CONCRETE MIX DESIGN

Specific gravity of fine aggregates. This is the ratio of solid density of sand particles to the density of water. Higher the specific gravity heavier is the sand particles and higher is the density of concrete. Conversely a lower specific gravity of sand will result in lower density of concrete.
