Typical range for fineness modulus of fine aggregates is 2.3 to 3.2. Higher value of fineness modulus means coarser sand. Lower value of fineness modulus means finer sand. Fineness modulus for fine, medium and coarse sand typically lies between 2.3 to 2.6, 2.6 to 2.9 and 2.9 to 3.2 respectively.@@happygirl5771
