Calculate the quantities of cement, water, fine aggregate, and coarse aggregate per trial mix of 1 m3 for the following specifications. Target mean compressive strength= 30 MPa at 7 days; Cement Type I; Slump required= 100 mm; Max. Aggregate size =20 mm; Specific gravity of aggregates = 2.65; Coarse aggregate UNCRUSHED (10, 20mm), fine aggregate CRUSHED (50% pass 600 micros); Maximum allowable free-water/cement ratio= 0.40; Minimum allowable cement content= 275 kg/m^3; Absorption of fine aggregate = 1.0%;
