Question
We require a mix with a mean 28-day Required Average Compressive Strength of 32 MPa the size of the member and the spacing of the reinforcement require a slump of 70 mm and a maximum size of aggregate of 32 mm. Portland cement type I is used with specific gravity of 3.15, dry-rodded unit weight of coarse aggregate 1750 kg/m³ and bulk specific gravity (SSD) of 2.55. The fineness modulus of fine aggregate is 2.8 and bulk specific gravity (SSD) of 2.5 ,No air entrainment is required. Neglect water absorption and moisture content of both aggregates. The aggregates conform to the ASTM C33-84 requirements for grading. Estimate the quantity of (cement, fine aggregate, coarse aggregate and water) for 1m³ concrete.
