Jul 14, 2020· Fineness Modulus. Fineness modulus is an empirical factor obtained by adding the cumulative percentages of aggregate retained on each of the standard sieves ranging from 80 mm to 150 micron and dividing this sum by 100. Fineness modulus is generally used to get an idea of how coarse or fine the aggregate is.

The specific gravity of aggregates indirectly measures its density; hence it is the most essential parameter of strength or quality of the aggregates. Higher the specific gravity, higher is the strength. It is due to higher specific gravity there would be higher compressive strength of aggregates and hence it passes on to the concrete. 02.
