What is the formula for calculating concrete?
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 much concrete do I need for a 10×10 slab?
For a 10 x 10 slab, we’d suggest a mix with a capacity of about 4,000 pounds per square inch, or psi. This is basic for residential projects, and it can withstand traffic and support heavy loads.
How much is 5 cubic yards of concrete?
Each cubic yard of concrete costs $119 to $147 per cubic yard delivered.
Short-Load Concrete Prices.
| Cubic Yards | Mixing On-site Fees |
|---|---|
| 5 – 5.75 | $70 |
| 4 – 4.75 | $80 |
| 3 – 3.75 | $90 |
| 2 – 2.75 | $100 |
How much concrete do I need for a 40×60 slab?
On average, the amount of concrete you will need for a 40×60 slab for a barndominium will be $9,500 to $14,400. This calculation takes into factor the area of the slab, the cost of the concrete mix, and the national average of labor and materials you will need for the job.
How much does 2 yards of concrete cost?
According to the NRMCA – Ready Mixed Concrete Industry Data Survey, the average cost of concrete in 2018 was $120 per cubic yard, or $240 for the 2 cubic yards needed for a typical 10-by-10-foot patio.

What is the correct mix for concrete?
In terms of the ratio for concrete, it depends on what strength you are trying to achieve, but as a general guide a standard concrete mix would be 1 part cement to 2 parts sand to 4 parts aggregates. For foundations, a mix of 1 part cement to 3 parts sand to 6 parts aggregates can be used.
How many square feet does an 80lb bag of concrete cover?
4 sq feet in that amount of cement.
How many square feet does 10 yards of concrete cover?
One Cubic Yard of Concrete: 4-inches thick – covers 81 square feet. 5-inches thick – covers 65 square feet. 6-inches thick – covers 54 square feet.
How thick should my 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.
Can I pour a 2 inch concrete slab?
If done properly, new concrete can often be poured right over an existing slab. For this to be feasible, the contractor needs to pour at least 2 inches thick, use smaller aggregate, and incorporate reinforcement such as welded wire mesh or fiber mixed into the concrete.
How many bags of concrete do I need calculator?
To determine how many bags of concrete you will need, divide the total cubic yards needed by the yield. Use the following yields per each bag size: 40 pound bag yields.011 cubic yards. 60 pound bag yields.017 cubic yards.
How many bags of cement do I need for 100 square feet?
Ans.:- 7.6 no of cement bags (381.30 kgs) are required for 100 sq ft rcc roof slab 4 inch thick m20 grade concrete.

How much concrete do I need for a 30×50 slab?
Concrete Slab Cost Calculator
| Size (in feet) | Approximate Cost |
|---|---|
| 30×30 | $5,400 |
| 30×40 | $7,200 |
| 30×50 | $9,000 |
| 40×40 | $9,600 |
Can pressure treated posts be set in concrete?
Simply setting the posts in concrete does create a condition that will accelerate rot in the bottom of the posts. With pressure–treated posts, the rot will be slow. Concrete should be poured around the post – no concrete under the post.
How much would a 30 by 40 garage cost?
An average 30×40, 1,200 sq ft, metal garage costs between $22,800 and $30,000, or $19-$25 per square foot.
