The composition of an air-entrained concrete is given below: Water : 184 kg/m3 Ordinary Portland Cement: 368 kg/m3 Sand : 606 kg/m3 Coarse aggregate : 1155 kg/m3 Assume the specific gravity of $\mathrm{OPC},$ sand and coarse aggregate to be 3.14,2.67 and 2.74 , respectively. The air content is liters/ $\mathrm{m}^{3}$.
