FINENESS MODULUS OF SAND

The fineness modulus is commonly used to determine the coarseness or fineness of an aggregate. A higher fineness modulus value suggests a coarser aggregate, whereas a lower fineness modulus value implies a finer aggregate. Sand with a fineness modulus of more than 3.2 is usually not being used to produce great concrete.
