Assume We need 1 m3 of wet volume concrete of M25 Mix, (Mix Ratio, M25 = 1: 1 : 2) So Total Parts = 1+1+2 = 4 Parts which gives Dry volume that means before adding water content. Volume of concrete = (1 Cement Part)/4 + (1 Sand Part)/4 + (2 Coarse Aggregate Part)/4. From the IS Code standard, Assuming the water-cement ratio for M20 is 0.5.
So enter in the footing calculator, 6" depth by 12" width (always figure steps with a 12" width) by 9' length. This totals .17 cubic yards. The total concrete needed for the 3' by 3' porch will be .28 cubic yards. (.11 + .17 cubic yards = .28 cubic yards) Repeat this for added layers of steps. 3' x 3' Porch.
Nov 04, 2020· Answer by Mihir Salanke: Mix proportion for M25 grade of concrete is 1:1:2(cement:fine aggregates:coarse aggregates). So if you need 4cu.m of M25 concrete, we need to have 1cu.m of cement. So, theoretically, for 1cu.m of M25 concrete, we need to have 0.25cu.m of cement. But in practice, whenever we estimate quantity of cement for concrete…

Method 3: Take a sample of each in a container/cistern (of equal volume) and fill them The CSA ratio of the M25 is 1: 1: 2, while that of the M30 is mix design (but is generally greater than M25). As the weight of the aggregate is dominating the mixture, the weight of the M30 sample will be greater. Thus, we can differentiate between samples.
of ingredients of a concrete mix is in the terms of parts or ratios of cement, fine and coarse aggregates.
