Fineness Modulus of Coarse Aggregates
The fineness modulus increases with aggregate size, hence coarse aggregate has a greater fineness modulus than the fine aggregate. When an aggregate is sieved via a 4.75mm sieve, it is said to be coarse aggregate. ... Dust each sieve in preparation for testing and arrange them all in a pyramid according to size.
