Concrete - Precast Fineness Modulus of Sand • The fineness modulus is calculated from the particle size distribution of the fine aggregate • Values for sand suitable for concrete should range between 23 and 31 • Values can’t differ by more than 02 • Coarse sand has a higher FM than fine sand • The FM influences the bulk volume of coarse aggregate
What is Bulking of Sand? Its Calculation, Classification This is because moisture in small proportions forms thin films around the sand grains Fine sands bulk greater than coarse sandWhen the moisture content is increased beyond 8-10 percent, the bulking of sand effect almost disappears In fact, sand grains settled in a water tank will have the same volume as dry sand
