Calculate the quantities of cement, water, and fine aggregate and coarse aggregate per trial mix of 0.07 m3 for the following specifications. Characteristic compressive strength = 50 MPa at 28 days; S=5 MPa %3D Cement Type I; Slump required = 30-60 mm; Max. Aggregate size = 10 mm; Coarse aggregate CRUSHED (10 mm), Fine aggregate CRUSHED (85% pass 600 microns) Maximum allowable free - water/cement ratio 0.50; Maximum allowable cement content = 550 kg/m3
