One 80 lb. bag of QUIKRETE Concrete Mix yields approximately 0.6 cubic feet when placed. If the hole has dimensions of 18 feet x 18 feet x 2 inches, the volume to be filled is ~54 cubic feet, and approximately ninety 80 lb. bags will be required to fill it. If the hole has dimensions of 3 feet x 6 feet x 2 inches, totaling 18 square feet x 2 inches, the volume to be filled is ~3 cubic feet, and approximately five 80 lb. bags will be required to fill it. This will be affected by uneven sub grade, waste, etc.

An 80 lbs. (36.3 kg) bag yields approximately 0.60 cu ft. (17 L), so for your project you would need approximately 55 bags (72inx28inx8in~9.3ft3 and 76inx53inx10in~23.3ft3, which gives you 32.6ft3 combined, which is then divided by the yield of 0.6ft3, which gives you ~55 80lb bags). These are estimates and will vary based upon waste, uneven sub-grade, etc.

Asked by

January 20, 2014
The number of bags required to set 18 posts 2 feet into the ground will depend upon the diameter of the posts, as well as the diameter of the holes. It is recommended to place 1/3 of the length of the post in the hole, so a 2 foot deep hole would be appropriate for a post that is 6 feet long. The typical recommended diameter of the hole is 3 times that of the diameter of the post. For example, if the diameter of the post is 2 inches, the recommended diameter of the hole is 6 inches. A single 2 foot deep hole that is 6 inches in diameter, for a post 2 inches in diameter will require approximately 0.6 80 lb bag, or 10.8 bags for 18 holes. A single 2 foot deep hole that is 9 inches in diameter, for a post 3 inches in diameter will require approximately 1.3 80 lb bags or 23.4 bags for 18 holes. A 2 foot deep hole that is 12 inches in diameter, for a post 4 inches in diameter will require approximately 2.3 80 lb bags or 41.4 bags for 18 holes. These are estimates, and will vary based upon waste, variation in diameter, etc.

Because concrete contains gravel / stone, it should not be utilized in applications that are less than 2 inches thick. QUIKRETE Sand / Topping Mix #1103, is appropriate for applications ½ to 2 inches thick. For an application that is ½” thick, it is suggested to replace half of the mixing water with QUIKRETE Concrete Acrylic Fortifier #8610. Ensuring a sound, stable, cementitious substrate (i.e. concrete slab) that is free of any “bond breakers” such as paints, sealants, or adhesives, before applying the Sand / Topping Mix is critical in ensuring a successful application. An 80 lb bag of QUIKRETE Sand / Topping Mix yields approximately 0.66 cubic feet of material, while a 60 lb bag yields approximately 0.5 cubic feet of material. For an application of 200 square feet that is ½” thick, approximately 8 1/3 cubic feet of material would be needed. This would require approximately 13 80 lb bags, or 17 60 lb bags of Sand / Topping Mix. If this application is NOT over a concrete slab, and is utilizing sand / dirt as the substrate, a ½” application would not be recommended. A standard concrete slab application over sand / dirt is 4 inches thick. Proper preparation of the area would be required, including excavating the slab area as needed. Typically 3 inches of tamped gravel is utilized as the sub-base. A 4” slab would be an appropriate use for QUIKRETE Concrete Mix, which yields approximately 0.6 cubic feet per 80 lb bag. For an application that is 4” thick, 200 square feet would require a total of approximately 66 2/3 cubic feet, or 112 80 lb bags of Concrete Mix. All yields are approximate, and will vary based upon waste, uneven sub-grade, etc.

Hello Tony48, I’m Chris from the Home Depot’s how-to Community. Thank you for your question.

Each 80 pound bag makes 0.6 cubic feet of concrete.

You have a need for 12’x3’x0.5’ or 18 cubic feet of concrete.

Therfore, 18 cubic feet / 0.6 cubic feet / bag = 30 bags.

I hope this helps,
Chris.

A single 1 ft (12”) x 0.5 ft (6”) x 0.5 ft (6”) footer will require approximately 0.25 cubic feet of concrete. Four footers will therefore require approximately 1 cubic foot of concrete. An 80 lb bag of QUIKRETE Concrete Mix yields approximately 0.6 cubic feet, so approximately 1 2/3 80-lb bags will be required. These yields are approximate and will vary based upon waste, uneven subgrade, etc. Be sure to check local building codes to ensure that your project is in compliance.

A standard concrete slab is typically 4 inches thick. Proper placement of rebar or concrete wire in a 2” thick slab would be difficult to successfully achieve. Advantages of including rebar and / or wire mesh can include reduction of random cracking, reducing and controlling crack width, minimization of displacement and curling, and increased strength. A solid sub-base, such as compacted gravel, will help prevent erosion and slab settling.

Hello Rey73,

You will need 78 bags of 80lb concrete to fill the area. When calculating concrete the first step is to figure out the square footage using the formula of "length x width", in this case it being 138sq ft.

Quikrete has a number of product calculators on their site which are of great use here: http://www.quikrete.com/Calculator/...

I hope this helps.
