fine sand modulus

  • The fine aggregate was natural river sand with a fineness modulus of 294 The coarse aggregate was crushed diabase with a maximum radius of 20 mm A water-reducing agent (FDN) and silica fume (average radius is 100 nm) were usedIn the present investigations, the effect of Fineness Modulus of sand has been investigated The Fine aggregate (Sand) taken is Yamuna river sand and coarse aggregate taken is Dolomite limestone in crushed form It has been sorted in several categories starting the Fineness Modulus (FM) of sand.

  • Fineness Modulus of Sand Why to Determine Fineness Modulus? Fineness modulus is generally used to get an idea of how coarse or fine the aggregate is More fineness modulus value indicates that the aggregate is coarser and small value of fineness modulus indicates that the aggregate is finerGEOTECHNICAL ENGINEERING FORMULAS A handy reference for use in geotechnical analysis and design , 12 USDA Soil Classification System The percent SAND,SILT,and CLAY lines are drawn and their intersection gives the , Fine Sand 0-50 Granular Materials (35% or less passing No 200) 0-35 0-35 0-35 0-35 0-30 0-15 0-50.
