Situation 2. Given the following data for a concrete mix:
Target Concrete Strength = 40 MPa
Slump = 75 mm to 150 mm
Water – Cement Ratio = 0.48
Unit Weight of Concrete = 23.4 KN/m 3
Water Content = 180 Kg/m 3
Entrapped Air = 1%
Fine Aggregate = 33% of the total volume of the aggregates
Specific Gravity of Materials:
Cement = 3.15
Fine Aggregate = 2.68
Coarse Aggregate = 2.64
