Mar 1, 1997 . The specification should also say if those proportions are by weight or volume. If the proportions are based on weight, use 4 pounds of coarse aggregate and 2 pounds of sand for every pound of cement. To make the concrete, though, you still need to know the required water-cement ratio. If the proportions.

Just remember 1.25 (it is volume of cement 50 kg bag in cft)If you use dimensions in meter then convert volume cubic meter to cubic feet by multiply 35.31 By Atish Kumar s.facebook/atishkc B-tech Civil.
Adding more water (Water Cement Ratio) on concrete to increase the concrete workability ? . Normally water cement ratio falls under 0.4 to 0.6 as per IS Code 10262 (2009) for nominal mix (M10, M15 …. M25) . Here comes the Water which will initiate this chemical process by adding 23%-25% of the cement volume.

Dec 21, 2016 . Loss of cement is considered as 2%. Output of mix is considered as 67%. To achieve 1 cum output, we need 1/0.67 = 1.49 say 1.50 cum dry mix. Now add the wastage of 2%, i.e (1.50 + 0.02) = 1.52 cum. Volume of cement = (cement/cement+sand+aggregate) × Total material. =(1/1+2+4) × 1.52. =0.2171.
The compressive strength of concrete is related to its water-cement ratio. A.1.3 For . A.2. Factor in the choice of mix design. The design of concrete mix is based on the following factors: a). Grade of concrete b). Type of cement and its strength . content and proportion of sand(as % of total aggregate by absolute volume) are.
The constant (A) is introduced as a rate of strength gain constant whereas, (B) is introduced as grade of strength constant. ..
