Q.1) Use the British method to design an air-entrained concrete trial mix with a wolume of (0.07) m³, if you know the following: The characteristic compressive strength at 28 days is (27) MPa, and k = 2.33, s-7 The used cement is ordinary Portland cement. The slump = 75 mm. The maximum free water to cement ratio = 0.50 (by weight). The minimum cement content= 300 kg/m³. The maximum cement content = 550 kg/m³. Air content 6.0%. Maximum size of aggregate = 20 mm. Type of aggregate: coarse: crushed, fine: uncrushed. % passing (0.6) mm sieve for fine aggregate = 70%.
