• ## Concrete Calculator how much concrete do you need in

Calculating how much concrete you need. Most builders face the task of calculating or estimating the amount of concrete needed to build a certain structure: a rectangular or round slab, a wall, supporting square and round columns, staircases and curbs and gutters. The process is as follows: Estimate the volume of concrete needed, using geometrical formulas and the construction plans. Learn the

• ## How to Calculate Cement, Sand and Aggregate required

Total weight of concrete ingredients = 50+115+209+27.5 = 401.5 say 400 kg. Density of concrete = 2400 kg/cum. So, 1 bag of cement produces = 400/2400 = 0.167 cum. No. of bags required for 01 cum of concrete = 1/0.167 = 5.98 bags ~ 6 bags. From above, if the concrete mix is 1:2:4 , to get a cubic meter of concrete we require. 1.Cement = 6 bags
