An 80 lb. bag of QUIKRETE Concrete Mix yields approximately 0.6 cubic feet of concrete. For a 48 sq. ft. slab that is 0.167 ft. (2 inches) thick, approximately 8 cubic feet of concrete, or approximately 13-14 80 lb. bags of concrete mix would be required. Note that a standard slab is typically 0.34 ft. (4 inches) thick, which would require twice as much concrete. Yields are approximate and will vary based upon waste, uneven sub-grade, etc.

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.

An 80 pound bag yields approximately .6 cubic feet of product. A rough rule of thumb is that you need 150 pounds of concrete per cubic foot of your design. So, a walkway that is 4" thick, 4' wide and 8' long would be 18,432 cubic inches or 10.67 cubic feet, needing a rough estimate of 1,600 pounds of concrete.

Asked by

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.

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.

It is set within 6 hours. If you live somewhere the wind doesn't blow and you pour the concrete early in the am, by evening you could build the fence. Personally, I would wait at least 24 hours. Pam

Assuming a 6" diameter post, you would need four bags per hole. However, your post may be larger and you would need less, or smaller and you would need more. Also, four feet of concrete is a massive amount, and you could probably get good results with two or three feet of concrete then a foot of two of tamped backfill dirt.
