[43. Determine the cement content of the concrete (air entrained) and the oven-dry weight of the coarse aggregate according to the following condition: Required design strength - 27.6 MPa: standard deviation of concrete (more than 30 samples) - 2.1 MPa: water content - 141 kg/m's oven-dry density of the coarse aggregate (19 mm nominal maximum size) - 1761 kg/m'; fineness modulus = 2.4, and minimum cement for 19 mm aggregate - 320 kg/m?
