It is pretty simple to figure out how much concrete you will need for a project around your home. Regardless of the size you will need to calculate the volume of the concrete needed in cubic yards prior to purchasing the bags or having the concrete delivered. So how much concrete is needed for a 10 ft by 10 ft concrete slab?
To figure out how many cubic yards you will need, multiply the length by the width by the depth. Calculating the depth is the toughest part of finding the cubic yards you will need. The standard thickness of a concrete slab is typically 4 inches. If the particular slab you are pouring will need to withstand very heavy vehicle traffic you should make the slab 5 or 6 inches in depth. For example we will use the 4 inch depth and convert that into feet. This means that you will use the depth of 0.35 feet when you calculate the amount of concrete needed. The equation will look like this 10 x 10 x 0.35
Once you come up with the number you will then divide it by 27, Which is the number of cubic feet in a cubic yard. The amount you will need for a 10 x 10 slab is 1.3 cubic yards, we always add an extra 10% to allow for any slab depth variations or spills that may occur. This is what your typical concrete contractor in Elk Grove does every day.
How strong is your 10 x 10 slab
Another Factor you will have to consider is the type of concrete needed for your project. Every type of concrete has three main ingredients: cement, water and aggregate such as sand or gravel. It is the proportions of each of these ingredients that determines the overall strength of the slab. For common 10 by 10 residential slabs we would suggest to mix with a capacity of about 4000 lb per square inch.
How many bags of concrete will you need for a 10 x 10 slab?
If you are completing your own home project you will need to know how many bags to buy at the store. A 60 lb bag will yield .017 cubic yards of concrete, an 80 pound bag will yield .022 cubic yards. So to break this down you would need 78 60lb bags of concrete mix 61 80lb bags of concrete mix which accounts for the extra 10% that we discussed earlier.
No matter what concrete project you are performing you can use this calculation to determine the amount of concrete you will need.
