Information on hand mix concrete.

It have to be listed that cement, is just one of the 4 items that makes up concrete. Concrete is a mixture the cement, aggregate, sand and water.

Square or Rectangle Concrete Slab:

*
Notes:

Pre-mix concrete come in bags that room 60 lbs. And 80 lbs.A 60 lb. Bag provides 0.45 cubic feet the cured concrete.A 80 lb. Bag gives 0.6 cubic feet the cured concrete.If you have concrete delivered it is offered by the garden (which is a cubic garden = 27 cubic feet).

Following room the recipe to calculate how much concrete you will call for for a square or rectangular shaped pour:

L (feet) x W (feet) x T (inches) ÷ 12 = cubic feet of concrete (CF)Number of bags the concrete needed:CF ÷ 0.45 = variety of 60 lb. BagsCF ÷ 0.6 = variety of 80 lb. BagsNumber that cubic yards that concrete needed:CF ÷ 27 = cubic yardsL = length in feetW = broad in feetT = Thickness in inchesCF = Cubic feet the concrete

Example:

A patio 10' long by 8' large - 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 the concrete

40 ÷ 27 = 1.5 cubic yards that 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 that cured concrete.If you have concrete ceded it is marketed by the garden (which is a cubic garden = 27 cubic feet).

Following room the recipe to calculate exactly how much concrete friend will need for a one slab:

3.14 x r (feet) x r (feet) x T (inches) ÷ 12 = cubic feet the concrete (CF)Number the bags of concrete needed:CF ÷ 0.45 = variety of 60 lb. BagsCF ÷ 0.6 = number of 80 lb. BagsNumber of cubic yards the concrete needed:CF ÷ 27 = cubic yardsr = radius that the circle in feet (1/2 of the diameter)T = Thickness in inchesCF = Cubic feet that concrete

Example:

A circle 6″ thick whereby the circle has actually a radius that 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 that concrete

47.5 ÷ 0.6 = 80 (79.2) 80 lb. Bags the concrete

47.5 ÷ 27 = 1.8 cubic yards the concrete

Notes:

Pre-mix concrete comes in bags that room 60 lbs. And 80 lbs.A 60 lb. Bag gives 0.45 cubic feet of cured concrete.A 80 lb. Bag offers 0.6 cubic feet that cured concrete.If you have actually concrete ceded it is sold by the garden (which is a cubic garden = 27 cubic feet).

Following are the recipe to calculate how much concrete you will need 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 the bags the concrete needed:CF ÷ 0.45 = number of 60 lb. BagsCF ÷ 0.6 = number of 80 lb. BagsNumber of cubic yards that concrete needed:CF ÷ 27 = cubic yardsr = radius that the one in inch (1/2 that the diameter)H = elevation in inchesCF = Cubic feet the concrete

Example:

A obelisk 8' high whereby the column has a radius that 5″ (10″ diameter tube)

3.14 x 5 x 5 x 96 ÷ 1728 = 4.4 cubic feet that concrete

4.4 ÷ 0.45 = 10 (9.8) 60 lb bags that concrete

4.4 ÷ 0.6 = 8 (7.3) 80 lb. Bags the concrete

4.4 ÷ 27 = 0.16 cubic yards of concrete
