Awasome Bags Of Concrete Calculator References. (all yields are approximate and do not. Please specify the mix ratio.
Use the following yields per each bag size: With this concrete calculator (in cubic meters/yards & bags), you can calculate the volume or number of bags of concrete needed for slabs, footings, walls, stairs, columns, and more. Enter the size of the slab you want to build in square feet.
Length x width x thickness. We use the following formula to calculate volume: Our calculator also works out the total concrete mix weight and required number of bags (using a standard 40lb bag of concrete which weights 145 pounds per cubic foot):
Please specify the mix ratio. Concrete premix bags are available in the following sizes: Simply enter your details into the above calculator to obtain an estimate.
By default, this concrete calculator uses a density of 150 lbs per cubic foot to calculate the amount of concrete needed for your project. To determine how many bags of concrete you will need, divide the total cubic yards needed by the yield. 1) square footage of concrete slab = length.
To determine how many bags of concrete you will need, divide the total cubic yards needed by the yield. 3.14 x r (inches) x r (inches) x h (inches) ÷ Enter the size of the slab you want to build in square feet.
(all yields are approximate and do not. Welcome to the concrete calculator. A bag of ready mix concrete weighing 80 pounds.
