  • How To Calculate Cement, Sand & Aggregates Quantity in

    Aug 03, 2018· Where 33, 43, 53 compressive strength of cement in N/mm2. M-20 = 1 : 1.5 : 3 = 5.5, (Cement : Sand : Aggregate) Some of Mix is 5.5. Where, M = Mix 20 = Characteristic Compressive strength. Consider volume of concrete = 1m3. Dry Volume of Concrete = 1 x 1.54 = 1.54 m3 (For Dry Volume Multiply By 1.54) Now we start calculation for find Cement

  • How much cement sand & aggregate required for M20 concrete

    Jul 26, 2020· How much cement required for M20 concrete in cubic metre step 4:-calculate cement required for 1 cubic metre of M20 concrete in cubic metre is equal to = 1/5.5 × 1.54 m3 = 0.28 m3. Ans. :-0.28 m3 ( cubic meter) cement required for 1 cubic metre of M20 concrete. How much cement required for M20 concrete in Kgs

  • How much cement is required for 1 cubic metre? Quora

    Formula used for, Density = Mass/Volume = 1440 kg/m3 So, Volume = Mass/Density Mass of 1 Bag cement = 50Kg Now we can calculate Volume by, Volume = 50/1440 = 0.034722 m3 Therefore, number of bags in 1 cubic meter,Nos. of Bags = 1/0.034722 = 28.8...

  • How many bags of cement do I need to make 1 cubic metre of

    Dec 30, 2011· 1 Cement 2 Sand 3 Aggregate (gravel) is too strong. 16bags (costly) 1 Cement 2.5 Sand 4 Aggregate is OK for fence posts. 13bags of cement per cubic metre. The more cement the more costly of course so don’t over do it. Note: These are 20kg bags of General Purpose cement.

  • Concrete Calculator Estimate Cement, Sand, Gravel

    Example 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.

  • How to Calculate Cement, Sand and Aggregate required for 1

    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
