(b). Calculate the amount of cement, water, fine aggregate, and coarse aggregate per trial mix of 0.005 m³ of concrete. Use the data listed below: (use the tables and graphs provided in the appendix and submit them together with your answer). Characteristic compressive strength (fc) = 30 N/mm? at 28 days, with a 2.5% defective rate Standard deviation = 8 N/mm? Portland cement strength class 42.5 Slump required = 10–30 mm %3D Maximum aggregate size = 20 mm granite?? Fine aggregate: 70% passing 600 µm sieve river sand?? Specific gravity of aggregate = 2.6 Maximum free-w/c ratio = 0.55 Minimum cement content = 290 kg/m³ Maximum cement content = not specified.
