May 17, 2017· To make ease in understanding we are finding the Concrete mix design of M20 grade concrete. The Concrete mix ratio for M20 grade of concrete is 1:1.5:3 that mean 1 part of cement, 1.5 part of sand (fine aggregate) and 3 parts of aggregate (crushed stone) in volume and then batched for mixing. To know the Concrete Mix Design follow below:-.
1m 3 of cement = 1440 kgs. 0.28m 3 of cement = 1440 x 0.28 = 403.2 kgs. For 1m 3 of Concrete = 403.2Kgs of Cement will be necessary. No. of Cement Bags necessary for 1m3 of Concrete = 403/50 = 8.06 ~ 8 bags. Therefore, 8 bags of cement is necessary for 1m3 of concrete.

Mar 13, 2013· Large Batches of Concrete Mixes. 15 Mpa This is a low-strength concrete mix and is suitable for house foundations that are not reinforced, and for boundary walls and freestanding retaining walls.. To make 1 cubic metre of 15 Mpa concrete you will need to mix 5 1/2 bags of cement with 0,75 cubic metres of sand and 0,75 cubic metres of stone.
Volume of Cement in Kg. = 1440 x 0.0028 Volume of Cement in Kg. = Density of Cement x Volume of Cement Volume of Cement in Kg. = 4.032 Kg We know that, The density of cement is 1440 kg per m 3; There are 0.08 cement bag is required for the plastering work of one square metre.; How to Calculate the Cement Sand Quantity for Plastering?
Wet volume of concrete = 1m3. mix ratio for m15 concrete = 1:2:4. We have to do following calculating steps:- Step 1 :-we have wet volume of concrete is equal to 1 cubic metre (1m3), but when we calculate actual quantity of dry ingredient cement, sand and aggregate of concrete. Dry volume of concrete is equal to 1× 1.54 = 1.54 m3 ( cubic meter)

Apr 07, 2020· For example, a simple sand and cement mix should be at least 3 part sand (the aggregate) to one part cement. A strong concrete mix would be something like 1:3:5 (Cement, Sand, Coarse Gravel). In this case, both the sand and gravel are the aggregate. In pre-mix concrete, the aggregate is already mixed with the cement.
