As we know density of fine aggregate is more compare to density of coarse aggregate because fine aggregate have less presence of air voids than coarse aggregate so density of aggregate 10mm is higher of other aggregate size density of coarse aggregate 20mm and 40mm ranging between 1200 1450 kgm3 75 90 lbft3 and density of fine
