Information on concrete sealers.
Information on hand mixing concrete.
It should be noted that cement, is one of the 4 items that makes up concrete. Concrete is a mixture of cement, aggregate, sand and water.
Square or Rectangle Concrete Slab:
Notes:
- Pre-mix concrete comes in bags that are 60 lbs. and 80 lbs.
- A 60 lb. bag provides 0.45 cubic feet of cured concrete.
- A 80 lb. bag provides 0.6 cubic feet of cured concrete.
- If you have concrete delivered it is sold by the yard (which is a cubic yard = 27 cubic feet).
Following are the formulas to calculate how much concrete you will require for a square or rectangular shaped pour:
L (feet) x W (feet) x T (inches) ÷ 12 = cubic feet of concrete (CF)
Number of bags of concrete needed:
CF ÷ 0.45 = number of 60 lb. bags
CF ÷ 0.6 = number of 80 lb. bags
Number of cubic yards of concrete needed:
CF ÷ 27 = cubic yards
L = Length in feet
W = Width in feet
T = Thickness in inches
CF = Cubic feet of concrete
Example:
A patio 10' long by 8' wide - 6″ thick
10 x 8 x 6 ÷ 12 = 40 cubic feet of concrete
10 x 8 x 6 ÷ 12 = 40 cubic feet of concrete
40 ÷ 0.6 = 67 (66.7) 80 lb. bags of concrete
40 ÷ 27 = 1.5 cubic yards of concrete
Circular Concrete Slab:
Notes:
- Pre-mix concrete comes in bags that are 60 lbs. and 80 lbs.
- A 60 lb. bag provides 0.45 cubic feet of cured concrete.
- A 80 lb. bag provides 0.6 cubic feet of cured concrete.
- If you have concrete delivered it is sold by the yard (which is a cubic yard = 27 cubic feet).
Following are the formulas to calculate how much concrete you will require for a circular slab:
3.14 x r (feet) x r (feet) x T (inches) ÷ 12 = cubic feet of concrete (CF)
Number of bags of concrete needed:
CF ÷ 0.45 = number of 60 lb. bags
CF ÷ 0.6 = number of 80 lb. bags
Number of cubic yards of concrete needed:
CF ÷ 27 = cubic yards
r = radius of the circle in feet (1/2 of the diameter)
T = Thickness in inches
CF = Cubic feet of concrete
Example:
A circle 6″ thick where the circle has a radius of 5.5' (11' diameter circle)
3.14 x 5.5 x 5.5 x 6 ÷ 12 = 47.5 cubic feet of concrete
47.5 ÷ 0.45 = 106 (105.6) 60 lb bags of concrete
47.5 ÷ 0.6 = 80 (79.2) 80 lb. bags of concrete
47.5 ÷ 27 = 1.8 cubic yards of concrete
Concrete Sonotube , Column Or Round Footing:
Notes:
- Pre-mix concrete comes in bags that are 60 lbs. and 80 lbs.
- A 60 lb. bag provides 0.45 cubic feet of cured concrete.
- A 80 lb. bag provides 0.6 cubic feet of cured concrete.
- If you have concrete delivered it is sold by the yard (which is a cubic yard = 27 cubic feet).
Following are the formulas to calculate how much concrete you will require for a circle, tube or column shaped pour:
3.14 x r (inches) x r (inches) x H (inches) ÷ 1728 = cubic feet of concrete (CF)
Number of bags of concrete needed:
CF ÷ 0.45 = number of 60 lb. bags
CF ÷ 0.6 = number of 80 lb. bags
Number of cubic yards of concrete needed:
CF ÷ 27 = cubic yards
r = radius of the circle in inches (1/2 of the diameter)
H = Height in inches
CF = Cubic feet of concrete
Example:
A column 8' high where the column has a radius of 5″ (10″ diameter tube)
3.14 x 5 x 5 x 96 ÷ 1728 = 4.4 cubic feet of concrete
4.4 ÷ 0.45 = 10 (9.8) 60 lb bags of concrete
4.4 ÷ 0.6 = 8 (7.3) 80 lb. bags of concrete
4.4 ÷ 27 = 0.16 cubic yards of concrete
