Concrete Mix Design. Calculate cement, sand and aggregate quantity in concrete. ... The nominal mix for M25 grade is (1:1:2). The quality of concrete depends on a number of factors and the standard mix just gives us a rough estimate of the quantities of material required, this is exactly where a design mix procedure is required as it is evident ...

Read More2020-6-12 Calculation of Volume of Cement in. Volume of cement= (cement/cement+sand+aggregate) x 1.54. Quantity of cement= (cement/total volume) x1.54. Thus Total no. of bags required for 1 ㎥ = 0.154/0.0347. Hence, we require 4.52 bags of cement for 1 cu.m of concrete. For 1 ㎥ of Concrete = 226 Kgs of Cement is required.

If design mix concrete cannot be used for any reason on the work for grades of M-20 or lower, nominal mixes may be used with the permission of engineer-charge, which however is likely to involve a higher cement -in content. Accordingly all concrete of above M-20 Grade for RCC work must be of ...
