Most concrete purchases will be made in cubic yards, which equates to 27 cubic feet. For example, a project measuring 10 ft in length by 10 ft in width with a depth of 3.5 in will be just over 1 cubic yard.
How many yards of concrete do I need for a 10×10 slab?
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.
How do you figure cubic yards of concrete?
Just follow these steps: Measure the area in feet. Multiply length by width, and then by thickness. Divide the resulting number by 27 to find cubic yards.
How many 80lb bags of concrete are in a cubic yard?
One 80lbs bag of Quikrete Concrete Mix will yield approximately . 60 cu ft. So it will take 45 bag to equal one cubic yard of concrete.
Is a cubic yard the same as a yard of concrete?
What Is the Difference Between a Yard and a Cubic Yard? A yard measures a two-dimensional area, and a cubic yard measures three-dimensional volume, or how much a space can hold.
Do you need rebar for 4 inch slab?
The thickness of rebar should be no more than 1/8 that of the slab, so a 4” slab shouldn’t have steel greater than #4 or 1/2″ bar. It’s best to check with a Structural Engineer if your slab will bridge or cantilever. What is this? For 4” concrete slabs used for driveways and patios, #3 rebar is common.
How many yards of concrete do I need for a 24×24 slab?
For example, for a concrete slab that is 24′ X 24′ X 4”, simply enter 4 in the Thickness/Depth field, 24 in the Width field, and 24 in the Length field. Click “Calculate”. Your answer should be 7.11 yards. Note: The Concrete Volume Calculator can also be used to determine yardage for aggregate products.
How much does it cost to pour a 24×24 slab of concrete?
A typical 24×24 garage slab costs between $3,057 and $5,944 with prices ranging from $5.31 to $8.31 per square foot for a 4” reinforced slab of concrete, and $6.83 to $10.32 per square foot for a 6” slab of reinforced concrete.
How many square feet is a yard of concrete 4 inches thick?
One Cubic Yard of Concrete: 4-inches thick – covers 81 square feet.
How thick should a concrete slab be?
Standard concrete floor slab thickness in residential construction is 4 inches. Five to six inches is recommended if the concrete will receive occasional heavy loads, such as motor homes or garbage trucks. To prepare the base, cut the ground level to the proper depth to allow for the slab thickness.
How many bags of concrete do I need for a 10×10 slab?
The thickness of your 10′ x 10′ slab will determine just how many bags you need. The average thickness of a 10′ x 10′ concrete slab for a shed is 4 inches thick. At 4″ thick, your 10 x 10 slab will take 56 bags of concrete that weigh 80 lbs.
How many 50lbs bags of concrete make a yard?
The number of bags you need will vary depending on the type of concrete mix you choose for your project. If you’re using 50lb bags of concrete, you’ll need 72 bags to make a yard. If you’re using 60lb bags of concrete, you’ll need 60 bags to make a yard.
How many bags of concrete do I need for a 4×4 slab?
As per calculation, for a 4×4 slab at 4 inch thick, generally you will need approximately either 12 bags of 60lb or 9 bags of 80lb of premixed concrete, at 5 inches thick slab, either 15 bags of 60lb or 11 bags of 80lb premixed concrete are required, while at 6 inches thick slab, either 18 bags of 60lb or 14 bags of.
What’s the difference between a cubic yard and a square yard?
To help you understand the difference between a cubic yard and a square yard, a cubic yard is three-dimensional. For example, a cubic yard can be one foot high, one foot wide, and one foot long. On the other hand, a square yard is two-dimensional, which means no height is involved.
What is the average cost of a yard of concrete?
The average cost of concrete is $117 per cubic yard, with a typical range between $104 and $144 per cubic yard. When you order less than a truckload of concrete, you’ll be charged a short load fee that averages around $43 per cubic yard.
How much cubic yards do I need?
Length in feet x Width in feet x Depth in feet (inches divided by 12). Take the total and divide by 27 (the amount of cubic feet in a yard). The final figure will be the estimated amount of cubic yards required.
Do you need gravel under concrete?
Whether you pour concrete for a walkway or patio, a strong gravel base is required to prevent the concrete from cracking and shifting. Gravel is especially important in clay soil because it doesn’t drain well, which results in water pooling under the concrete slab and slowly eroding the soil as it finally drains.
Can you use chicken wire in concrete?
Chicken wire or wire mesh can be safely used as a reinforcement in concrete when the concrete is not used in structural or high-weight areas. The wire mesh or chicken wire can add stretching strength that concrete does not have, giving the concrete rigidity when facing specific pressures.
Which is better rebar or wire mesh?
In summary, rebar vs wire mesh can have costly differences. Rebar remains stronger and ensures consistent contact in the soil where as wire mesh is unpredictable and often results in a week concrete foundation.
