Using Density of Cement = 1440 kg/cum (Approx) Volume of 1 Kg of Cement = 1/1440 = 0.00694 cum. Volume of 01 bag (50 kg) of cement = 50 X 0.00694 = 0.035 cubic meter (cum) Since we know the ratio of cement to sand (1:2) and cement to aggregate (1:4) You’re still using the same density of cement for both sand and aggregate.

Learn MoreA standard bag of cement weighs 50kg so the equivalent quantities and weights are: 1 Bag cement = 50kg = 0.2 m 3 (cubic metre) Below is the nominal mix proportions (also referred to as the ratios of mixes) for different strength categories, using a 19mm stone. NB. Low would be average 15MPa, medium 25MPa and high 35MPa.

Learn MoreExample calculation Estimate the quantity of cement, sand and stone aggregate required for 1 cubic meter of 1:2:4 concrete mix. Ans. Materials required are 7 nos. of 50 kg bag of cement, 0.42 m 3 of sand and 0.83 m 3 of stone aggregate.

Learn MoreConcrete mixes normally require about 1 liter per +/- 13 kg of concrete mix. For a 40kg bag we are talking about +/- 3 liters of water. Concrete preparation . The preparation of concrete involves the mixing of materials such as: cement, sand, gravel and water.

Learn MoreThe mix ratio of 1:2:3 consists of 1 Part cement, 2 Parts sand, and 3 Parts stone (plus some water) to make a concrete mix you can use for most any building project. The way you measure the ratio could be in shovels, buckets, or wheel barrows.

Learn MoreThen finding out how many packs or bags of dry concrete/dry concrete mix you have to buy for the calculated volume is a bit trickier. So if you want to mix concrete to fill a certain cubic meter and want to know how many bags of 25 kg concrete, 35 kg concrete or 40 kg concrete each can be bought, then you’ve come to the right place.

Learn MoreM15 Ratio = 1:2:4 which consists of 1 part of cement, 2 part of Fine aggregate(sand), and 4 part of Coarse aggregate. The total volume of concrete = 1 cum (wet volume ...

Learn MoreThe table below gives you the concrete mix ratios and converts them into kg to make 1m3 of concrete. Manufacturing concrete using this method is a good guide but too much cement is used. Prescribed Concrete Mixes. A prescribed concrete is a mix where the purchaser prescribes the exact mix.
