How much concrete do I need calculator?
How much concrete do I need calculator?
How to calculate concrete:
- Determine how thick you want the concrete.
- Measure the length and width that you’d like to cover.
- Multiply the length by the width to determine square footage.
- Convert the thickness from inches to feet.
- Multiply the thickness in feet by the square footage to determine cubic feet.
How many bags of concrete do I need for a 12×12 slab?
Regarding this, “how many bags of concrete do I need for a 12×12 slab at 4 inch thick?”, its depend on thickness of slab, at 4 inches thick, generally you will need approximately either 104 bags of 60lb or 80 bags of 80lb (1.76 cubic yards or 47.52 cubic feet or 1.35 m3) of premixed concrete for a 12×12 slab.
How do you figure concrete yardage?
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 much concrete do I need for a 10×10 slab?
At 4″ thick, for a 10×10 slab, generally, you will need 1.23 cubic yards or 33 cubic feet or either 74- 60lb or 56-80lb bags of premixed concrete.
How many yards are in a 24×24 concrete slab?
7.11 yards
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 do you calculate concrete mix ratio?
The prescribed Nominal Concrete Mix Ratio of M20 grade concrete is 1:1.5:3.
- Cement = 1 Part.
- Sand = 1.5 Part.
- Aggregate = 3 Part.
- Total dry volume of ingredients required = 1.57 cu.m.
How do you figure cubic feet of concrete?
To determine how many cubic feet you need for a hole, measure the length, width, and thickness together, all measured in feet. So a 4″ thickness is 4″/12″ or 0.333 feet. The result of this Length x Width x Thickness multiplication is cubic feet.
How many bags of quikrete do I need for a 10×10 slab?
At 4 inch thick, for a 10×10 slab, you will need either seventy four 60- pounds or fifty six 80- pounds or 112- 40- pounds bags of concrete. Thus, either 74- 60lb or 56- 80lb or 112- 40lb bags of concrete will be required for a 10×10 slab at 4″ thick.
How many 80lb bags of concrete do I need for a 10×10 slab?
Does a 10×10 concrete slab need rebar?
Do concrete patios need rebar? Even though it’s possible to build a concrete patio without rebar, it’s not recommended. All concrete is subject to cracks, but rebar holds all the cracks together and keeps the slab level and even. Without rebar, the cracks would become quite wide and the concrete would become uneven.
