How Much Concrete Do You Need? Use the Readymix Concrete Volume Calculator to calculate the volume of concrete you require for your job. If you are not sure of how to calculate the volume of different shapes, you can use the Common Shape Calculator which will provide you with the appropriate equations. *1m³ minimum order value.

Use this calculator to determine how much sand, aggregate (gravel) and cement is required for mixing on site a given area of concrete (1:2:4 ratio). Please enter the dimensions in the white fields below and click calculate to display the results. See below for help on concrete. Dimensions: Length in metres Width in Metres Depth in Millimetres Total m3 Materials: 25 Kg bags: 40 Kg bags: 1 tonne

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.

These Concrete Calculators provide the required quantities of cement and all-in ballast or cement, sharp sand and gravel required to give a defined volume of finished concrete. Both of these concrete calculators make an allowance for the fact that material losses volume after being mixed to make concrete. Calculator are provided for a general mix and a paving mix, the different ratio of

Our concrete calculator allows you to accurately work out the amount of concrete you'll need for your project. Simply add the measurements for your concrete order to the relevant shapes above (you only have to fill in the shape/s you want to use) You can build up a concrete calculation for complicated areas by adding additional shapes of each type.

30/12/2011· Here is a good example of what is required from Boral’s Site. From my learnings: 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

Calculating how much concrete you need. Most builders face the task of calculating or estimating the amount of concrete needed to build a certain structure: a rectangular or round slab, a wall, supporting square and round columns, staircases and curbs and gutters. The process is as follows: Estimate the volume of concrete needed, using geometrical formulas and the construction plans. Learn the

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

26/12/2017· The requirement of cement in 1 m3 of concrete will depend on the grade of concrete suppose for M20 grade of concrete proportion is 1:1.5:3 volume of dry Concrete = 1.54 to 1.57 times Volume of wet concrete Lets assume 1.57 So, volume of cement =ce...

These Concrete Calculators work out the required cement and all-in ballast or cement, sharp sand and gravel required to complete a user defined volume of finished concrete. Both concrete calculators make an allowance for the fact that ballast etc losses volume when mixed to make concrete. Two Concrete Calculator are provided for different concrete mixes: General mix 1:5 cement:all-in ballast

Coarse Aggregate = (Coarse Aggregate Part / Concrete Parts ) * Concrete Volume = (3/5.5) * 2 = 1.09 m 3 . Water Cement Ratio. According to IS 10262 (2009), Assuming Water-Cement Ratio for the Concrete as 0.45. Required Amount of Water = W/C Ratio X Cement Volume. Therefore, Water = 0.45 X 0.3636 m 3 = 0.16362 m 3

The proportions of materials for a C20 and C20P (P = Portland cement) concrete mix are: 1 part cement; 2 parts fine aggregate (sand) 4 parts coarse aggregate; If you are using premixed ballast, then: 6 parts pre mixed ballast; 1 part cement; In an ideal world, where everything is delivered dry, a water to cement ratio of approximately 0.55

This will have little impact on the cost of an industrial concrete but could add £2 £3/m 3 on a lower grade footing concrete. You will also need to consider how wet the concrete needs to be: the price will increase the wetter the concrete is as the supplier will need to add more cement to keep the strength the same. It is important you do not simply add water on site as this will reduce

28/04/2017· 1 m3 of concrete = 2400Kg Concrete mix, 1 part cement, 3 parts sand, 3 parts aggregate. Therefore cement is 1/7th of concrete. 2400/7 = 343 Kg of cement required or about 7

23/04/2018· Use this to figure how much material you need for the subgrade. Using a Margin of Safety: Problems Caused by Underestimating the Amount of Concrete. Never try to order the exact amount of needed concrete. Include a margin of safety. A perfectly placed order of concrete will finish the job with a small amount left over. A 20 cubic yard order

Q. How many bags of cement are needed to mix one cubic meter of concrete? A. One cubic meter of concrete is equal to 1.308 cubic yards of concrete. If there are 5 1/2 bags of cement in 1 cubic yard of concrete, there would be 7.2 bags in 1 cubic meter of concrete. These are the 94 pound bags of portland cement or 42.64 kg bags of cement.

Coarse Aggregate = (Coarse Aggregate Part / Concrete Parts ) * Concrete Volume = (3/5.5) * 2 = 1.09 m 3 . Water Cement Ratio. According to IS 10262 (2009), Assuming Water-Cement Ratio for the Concrete as 0.45. Required Amount of Water = W/C Ratio X Cement Volume. Therefore, Water = 0.45 X 0.3636 m 3 = 0.16362 m 3
