How do I calculate how much concrete I need for a slab? 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 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 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.
What is the formula for calculating concrete?
Use the formula. Calculating the volume for concrete requires using three dimensions: length times width (which is area) times the height (thickness) or L x W x H. If you are using feet as your standard unit of measurement, this formula will give you the volume of concrete in cubic feet.
How do I figure how much concrete I need?
Multiply the width times the length times the height (W × L × H), or use our volume calculator to find the cubic feet. Convert the volume to cubic yards from cubic feet. To do so, divide the cubic footage by 27 to get the yards of concrete needed.
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 much does an 80 pound bag of concrete cover?
80 lb bag of concrete cubic feet 80 lb bag of concrete yields 0.60 cubic feet which is approximately around 0.0222 cubic yards that will cover around 3.6 sq ft area up to standard depth of 2 inch excavation or backfills, and for 1 cubic feet of landfill you will need 1.66 bags of 80 lb concrete.
How much area does a 40 lb bag of concrete cover?
Regarding this, how much does a 40 lb bag concrete cover, as 133 lb concrete = 1 CF, so a bag of 40 lb concrete = 40/133 = 0.30 CF, therefore, a 40 lb bag concrete approximately cover around 1.8 square feet area upto depth of 3 inch.
How much area does an 80 pound bag of concrete cover?
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.
How do I calculate square feet into yards of concrete?
To convert square feet to cubic yards, you simply multiply your square footage figure by the height or depth of the area (in feet) to get a volume measurement in cubic feet. You then divide the total by 27 to get your measurement in cubic yards.
What are the dimensions of a cubic yard of concrete?
Likewise, a cubic yard (yard = 3 feet) is a cube 3 feet by 3 feet by 3 feet or 27 cubic 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 80 lbs bags of concrete make 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. If you have a project over a 1/2 a cubic yard you should consider our Mix On-site Concrete especially if you are hand mixing.
How much ballast and cement do I need calculator?
ballast calculator for concrete:-quantity of ballast for 1m3 concrete is calculated as follows, ballast quantity = 5/6 × 1m3 = 0.833 m3, we know weight of ballast = volume × density, so weight of ballast in kg = 0.833m3 × 1750kg/m3 = 1458kg, if weight of ballast bag is 25kg, then number of bags of 25kg ballast as 1458/.
How many yards of concrete can a truck hold?
Each cubic yard costs about $65. However, a fully loaded cement truck will hold 10 cubic yards—and partial “short” loads cost $15 to $20 extra for every cubic yard less than a full load.
How thick should a concrete driveway be?
As for thickness, non-reinforced pavement four inches thick is standard for passenger car driveways. For heavier vehicles, a thickness of five inches is recommended. To eliminate standing water, the driveway should be sloped towards the street a minimum of one percent, or 1/8 inch per foot, for proper drainage.
How much would it cost to pour a 30×40 concrete slab?
How much does a 30×40 concrete slab cost? The average cost is $4 to $8 per square foot. The median price is about $6 per square foot. Based on these averages, you may pay $4,800 to $9,600 with a median estimate of $7,200.
How much concrete do I need for a 30×30 slab?
18 yards of 3000 psi concrete mix @ 135.00 per yard. Wire mesh reinforcement. A double row of #4 rebar around the edges. Labor to form the slab.
