# How many bags of quickcrete for 4’x4′ slab?

Quikrete’s Concrete Mix yield’s about .15 cubic feet for every 20 pounds of mix, so a 40-pound bag yields .30 cubic feet, 60 pounds of concrete mix yields .45 cubic feet and an 80-pound bag yields .60 cubic feet.

One article claimed that You’ll also get the number of 40-pound, 60-pound, or 80-pound bags of concrete are needed for the project. For example, a 10′ x 10′ slab that is 4″ thick will need an estimated 1.23 yards 3 or 74 60lb bags of concrete and will cost roughly \$100.

Another thing we wanted the answer to was how many bags of Quikrete® fast-setting concrete do I Need?

One source proposed the calculator will indicate the number of 50 lb. Bags of QUIKRETE® Fast-Setting Concrete you need. For 2 inch post diameter / 6 inch hole diameter: For 3 inch post diameter / 9 inch hole diameter: For 4 inch post diameter / 12 inch hole diameter:.

The best way to calculate how much concrete you will need in cubic yards is to do the following: Mark your area that needs concrete and divide it into smaller areas. Calculate the volume of your area after determining its shape (see the examples below) by multiplying it with the thickness of the concrete. Convert the volume from feet to cubic yards to get a precise number of concrete that you need – in cubic yards.

## How many bags of pre-mix concrete to fill a yard?

Refer to table below that shows the coverage of different sizes of pre-mix bags. On average it will take 90 40lb bags, 60 60lb bags, or 45 80lb bags to fill one cubic yard of concrete. Add 5%-10% additional material to account for settling, spillage, and waste.

While we were researching we ran into the inquiry “How many bags of concrete are in a cubic yard?”.

On average, it will take 90 40lb bags, 60 60lb bags, or 45 80lb bags to fill one cubic yard of concrete. Add 5%-10% additional material to account for settling, spillage, and waste. [2] This will ensure you can complete your project in a single pour without needing to get more concrete to complete the project if you’re short.

You will need 45 bags of concrete mix to make a cubic yard of concrete. An 80 lb bag ( 36.3 kg) of concrete mix yields approximately 0.60 cubic feet (17L) There’s 27 cubic feet of concrete in a cubic yard. If you divide 27 by.60 it equals 45 bags.

## Is Quikrete as good as concrete?

Quikrete, or rapid-set concrete, is just as strong as regular concrete and able to withstand similar force. Quikrete offers different PSI strength ratings from 4,000 PSI to 6500 PSI. Regular concrete PSI ranges from 2,500 to 5,000 except for engineered concrete strength which can be up to 10,000 PSI.
