How many square feet will 3 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.
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 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. Ans.:- 7.6 bags (381.30 kgs), 9.5 bags (476.10 kgs) & 11.4 bags ( 570.8 kgs) cement are required for 100 sq ft rcc roof slab 4 inch, 5inch & 6 inch thick respectively in m20 grade of concrete.
How many bags of concrete makes a yard?
On average, it will take 90 40lb bags, 60 60lb bags, or 45 80lb bags to fill one cubic yard of concrete.
How do you calculate RCC?
Lets take example of RCC Column, where reinforcement required is 2.5% of concrete volume, weight of steel required will be: =196.25 kg.
d) Estimation of Reinforced Steel:
- For slabs = 1.0 % of concrete volume.
- For Beam = 2 % concrete volume.
- For column = 2.5 % of concrete volume.
- For RCC Roads, 0.6% concrete volume.
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 do you calculate RMC for a slab?
Calculating the top surface area and multiplying it with the depth or height of the column.
- Volume of Concrete = 0.6×0.4×3= 0.72m3
- Volume of Circular column = πr2 x 3 = 3.14 x 0.252 x3 = 0.58m3
- Volume of concrete = 1.2x1x0.1 = 0.12m3 Total volume of concrete required for footing= 0.32+0.12=0.44m3
How much does it cost for a 12×12 concrete slab?
How much does a 12×12 concrete slab cost? The average cost to pour a 12×12 concrete slab that is 4” thick is between $888 and $1,584, with professional labor and materials included.
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.
Is it cheaper to mix your own concrete?
One of the least expensive ways to get concrete is to mix your own. You can buy bags of the mix from a home improvement store. Typically, you only have to add water for it to be ready to pour. Otherwise, you risk getting a weaker concrete once it cures, which could lead to cracks or crumbles within a couple of years.
How many square feet does an 80lb bag of concrete cover?
4 sq feet in that amount of cement.
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.
How many cubic feet are in a 60 pound bag of concrete?
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.
