Step 5: Estimation of Coarse Aggregate proportion-From Table 3 of IS 10262- 2009 Volume of coarse aggregate for water-cement ratio of 0.50 =0.64 (Corresponding Zone III) In this case w/c = 0.4 lower by 0.10.One bag of cement and other ingredients can produce = 400/2400 = 0.167 Cum of concrete (1:2:4) 01 bag cement yield = 0.167 cum concrete with a proportion of 1:2:4. 01 cum of concrete will require. Cement required = 1/0.167 = 5.98 Bags ~ 6 Bags. Sand required = 115/0.167 = 688 Kgs or 14.98 cft.
