How to Calculate Cement, Sand, Aggregate Quantity of Concrete

  CONCRETE CALCULATION Cement, Sand, and Aggregate Quantity     Slab on grade   Floor slab size: 10'-0" x 10'-0" x 0'-6"   Volume → 50 cft   Wet volume of concrete: 50 cft   Dry volume of concrete = ?   The dry volume of concrete = 1.54 x The wet volume of concrete.   Wet concrete is composed of cement, fine aggregate, coarse aggregate, and water.             Dry volume of concrete Dry concrete is composed of cement, fine aggregate, and coarse aggregate.   Void Ratio Compressibility of materials used in 1 m3 of concrete Coarse Aggregate = 32% Fine Aggregate =20% Cement is neglected (due to fine particles). Wastage = 2–10% (we take 2%) Total void ratio = 32 + 20 + 2 = 54%     The percentage of voids caused by cement is 10%. The percentage of voids caused by fine aggregate is 12%. The percentage of voids caused by coarse aggregat...
