Essentially you are solving for volume and then converting to cubic yards. For concrete, the formula for volume is as follows: length x width x thickness. To determine how many bags of concrete you will need, divide the total cubic yards needed by the yield. Use the following yields per each bag size: 40 pound bag yields .011 cubic yards
18 x 2 Inches thick or 1/6 Ft. = 3 This equals to 3 x = 2 bags of 80# concrete NOT 14 bags. I have 40 by 3 inch thick (1/4 Ft) area to be filled with concrete, which will take 6 bags of concrete. If I''m wrong in my figures, please let me know. Thanks, Floyd Smith frsmith31 or .

Density of concrete = 2400 kg/cum. So, 1 bag of cement produces = 400/2400 = cum. No. of bags required for 01 cum of concrete = 1/ = bags ~ 6 bags. From above, if the concrete mix is 1:2:4, to get a cubic meter of concrete we require. = 6 bags = 300 kgs. Aggregate = 115/ = 689 kg
Dec 21, 2016· ∴ No. of cement bags required in 1 cubic meter = / = bags. Note: You can use the same formula for calculating cement for other nominal mixes.
You''ll need to use the weight of one bag of cement to calibrate your "part" measurements. For instance, if you''re using 80pound bags of cement, one "part" equals 80 pounds. Thus, for a standard mix using 80pound bags, you''ll need 40 pounds of water (80 x 1/2 = 40), 160 pounds of dry sand (80 x 2 = 160) and 80 pounds of crushed stone aggregate.
Concrete Calculator is a quick and easy way to calculate the volume, weight, and number of bags of concrete you need per project. Perfect for slabs, walls, columns, tubes, curbs, and stairs just to name a few. We love to stirfry and mix things up here with all sorts of internet businesses. Contact us.
Now that you used the concrete calculator to estimate how much concrete you need for your project, you should decide if you need a readymix concrete or a bagged solution. The truth is, larger jobs such as driveways are often easier to complete when ordering concrete by the yard instead of mixing it bag after bag manually.
