### Mix Design M-40 Grade - Civil Engineering

Considering 20 mm : 10mm = 0.6 : 0.4. 20mm = 701 kg . 10mm = 467 kg . Hence Mix details per m 3. Cement = 400 kg Water = 160 kg Fine aggregate = 660 kg Coarse aggregate 20 mm = 701 kg Coarse aggregate 10 mm = 467 kg Admixture = 0.6 % by weight of cement = 2.4 kg. Recron 3S = 900 gm. Water: cement: F.A.: C.A. = 0.4: 1: 1.65: 2.92 . Advertisements . Observation: – A. Mix was cohesive .
