IS 456-2000 has designated the concrete mixes into a number of grades as M10, M15, M20, M25, M30, M35 and M40. In this designation the letter M refers to the mix and the number to the specified 28 day cube strength of mix in N/mm2. The mixes of grades M10, M15, M20 and M25 correspond approximately to the mix proportions

Circular Column, Volume = πr 2 h= 3.141256 X (0.15) 2 X 5 = 0.35 m 3 . Concrete Ingredients Calculation. For Cement, Sand and Coarse Aggregate. This is a Volumetric Calculation. Assuming we need 2 m 3 of concrete for M20 Concrete Mix, (Mix Ratio, M20 = 1 : 1.5 : 3) Total Part of the Concrete = 1+1.5+3 = 5.5 Parts

so we can say, Volume of dry concrete = 1.54 to 1.57 times the volume of wet concrete I m assuming 1.54 as a safety factor Therefore, the total volume of concrete required is 1.54 ㎥. As per IS456:2000, M-10 Grade concrete proportion is = 1 : 3 : 6. Remember, here (1:3:6) indicates: 1 for cement. 3 for sand. 6 for aggregate

The volume proportion in weight turns out to be. Cement : Sand : Aggregate (in Kgs) is 50 kgs : 115 kgs : 209 kgs (by weight) Water required for the mixture = 27.5 kgs. 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

Hence, to prepare 1 cubic meter of M20, M15 and M10 concrete, 1.57 cubic meters of "total dry volume" of cement, sand and aggregate are needed, whereas to prepare 1 cubic meter of M7.5 and M5 concrete, 1.52 cubic meters of "total dry volume" of cement, sand and aggregate are needed. Many websites are giving different values for the "total dry volume" of the ingredients.

Ready-Mix Concrete. To save time, many builders order ready-mix concrete prepared to their specifications. Engineers create formulas before the project begins. These formulas go to the central plant, which mixes the concrete to the specified ratios. Engineers receive ready-mix concrete via the familiar cement mixer trucks.

Volume of concrete required for 4 cubes = 4 x (0.15 3 x1.25) = 0.016878 m 3 Cement = (384.8 x 0.016878) kg/m 3 = 6.66 kg Water = (197.4 x 0.016878) kg/m 3 =3.33 kg Coarse aggregate = (1073.33 x 0.016878) kg/m 3 =18.11 kg Fine aggregates = (790.3 x 0.016878) kg/m 3 = 13.34 kg In this case, Slump value = 60 mm Compaction Factor = 0.852 So, from ...

Just as the name implied, concrete mixer truck capacity, means exactly how much concrete that mixing drum can hold, mix, and provide. In fact, the capacity or specification of concrete mixer truck is same as the mixing drum on it. If customers want to buy concrete mixer trucks, it is very imperative to choose a proper cement truck capacity.
