Question

Explain how can we find out specific gravity of an aggregate mix that contains both coarse and fine aggregates.

Answer 1

Specific gravity is the ratio of the density of the given mix with respect to the ratio of any reference substance. The reference substance is generally taken as water.

Here we have assumed the mix to contain only Coarse aggregate and fine aggregate as nothing is mentioned in question about water content and void ratio. But generally the mix also contains water and voids.

We have drawn phase diagram and found out the required specific gravity.
