What is the finess modulus of sand?.. Answer / dr savitha natak. Fineness modulus of sand is an index arrived based on the particle size analysis and then dividing the sum of the cumulative percentage of particles retained on the sieves by 100. it is important to note that higher the fineness modulus, higher is the coarser portion of the sand.
