A 60 lb. bag of QUIKRETE Concrete Mix yields approximately 0.45 cubic feet per bag. A 6 inch (0.5 ft) x 6 inch (0.5 ft) x 48 feet application would require approximately 12 cubic feet of concrete, or approximately 27 60 lb bags. This is an estimate and will be affected by uneven sub-grade, waste, etc.

An 80 lb bag of QUIKRETE Concrete Mix yields approximately 0.6 cubic feet. Standard slabs are typically 4 inches (0.34 feet) thick. For a 900 square foot area, 4 inches thick, approximately 306 cubic feet of concrete, or 510 80 lb bags will be needed. This is an estimate and will vary based upon waste, uneven sub-grade, etc.

Hi Touka, 900 square feet is a decent size area. If you are pouring a 4 inch slab you will need 505 bags of 80 pound quikrete. If you pour a 6 inch slab, you will need 748 bags of 80 pound quikrete. That is a lot of work. It would be a lot easier to have it trucked in.

No. Quikrete is premixed at the right ratio of portland cement, sand and aggregate. Adding more sand would change the ratio to the point where you would not get "concrete".

The QUIKRETE® Concrete Mix is a preblended mixture of sand, rock, and cementitious materials. The addition of any materials beyond the specified water quantity will affect the properties of the mixture. This may not be the product that will best suit your needs, we recommend that you discuss your project with your local Home Depot representative at the Pro Desk or call QUIKRETE® directly.

It is not clear if you plan on removing the existing walkway in its entirety, or whether you simply have areas that need repairs. An 80 lb bag of QUIKRETE Concrete Mix yields approximately 0.6 cubic feet of concrete. To replace the walkway in its current dimensions would require between 8 to 9 80 lb bags. Sidewalks are more commonly 4 inches thick, which would require 17.5 80 lb bags. These estimates are approximate, and will vary based upon waste, uneven subgrade, etc. If you instead plan on repairing the walkway, depending upon the damage, different products will be appropriate for repair. QUIKRETE Vinyl Concrete Patcher is designed for making repairs to small areas of concrete surfaces which are cracked, chipped, or spalled. It is not intended to be used for deep patches or large areas. QUIKRETE Commercial Grade FastSet Repair Mortar is a polymer modified, rapid setting repair material specially formulated to make structural repairs to any concrete or masonry surface, horizontal or vertical. It can be built up to at least 1 ½” in a single application. Once you make the necessary repairs, you may consider top coating the entire walkway (while maintaining the control joints) with QUIKRETE Sand / Topping Mix. If the majority of the area will require an application that is at least 1 inch thick, it is suggested that QUIKRETE Bonding Adhesive be used to coat the clean, unsealed, prepped surface before applying the Sand/Topping Mix. If the majority of the area will require an application that is less than 1 inch thick, it is suggested the QUIKRETE Concrete Acrylic Fortifier be blended with the Sand/Topping Mix, to replace a portion of the water, before applying the Sand/Topping Mix to the clean, unsealed, prepped surface.

Asked by
QUIKRETEProductExpert
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.

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 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.
