Fundamentals of Concrete

For conventional concrete the fineness modulus of the fine aggregate should range from 2.3 to 3.1. A higher fineness modulus represents a coarser material and a lower fineness modulus represents a finer material. Knowing the fineness modulus of aggregate gives you some indication of the amount of paste needed to make concrete using the aggregate.
