We require a mix with a mean 28-day compressive strength of 40 MPa the size of the member and the spacing of the reinforcement require a slump of 45 mm and a maximum size of aggregate of 28 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.

Three concrete mixes with the same ingredients, except the amount of mixing water, and their slump values were obtained. Three 100 mm * 200 mm concrete cylinders were prepared for each mix. The cylinders were cured for 7 days and then tested for compressive strength. The test results are as shown. Assume that the aggregate was at the saturated surface-dry condition before adding mixing water.It is required to do the following:a. Determine the compressive strength of each cylinder after 7 days.b. Determine the average compressive strength of each mix after 7 days.c. Determine the w/c ratio for each mix.
