What Is The Fineness Modulus Of Natural Sand

What is the fineness modulus of sand Answers. Finess Modulus is just a value (number) indicating the fineness or coarseness of the aggregate. So, a river sand (natural sand) will be in the range of2.5 or so to 2.7 and P-gravel (P-stone, Birds-eye) may be around 5.0 Natural sand is used to make concrete block.
