Yes, it is a great product with a setting time that allows time to work with the product, but sets quickly enough to get the job done in a timely fashion.
Each 50 lb bag of QUIKRETE® Crack Resistant Concrete Mix will yield approximately 0.375 cu ft. For a 32’ by 16” sidewalk at 4” thick, you will need 14.2 cubic feet of concrete 38 50-pound bags of concrete. Yields are approximate and will vary with waste, uneven subgrade, etc.
Each 80-pound bag of QUIKRETE® Crack Resistant Concrete Mix will require between 6 and 8 pints of water to achieve a workable consistency. Each 50-pound bag will require 3-3/4 to 5 pints of water to achieve a workable consistency.
QUIKRETE® Crack Resistant Concrete Mix does not require reinforcing steel for slabs on grade like sidewalks.
None of the cementitious products will bond to the asphalt side of the driveway. The concrete side can be updated with QUIKRETE® ReCap Concrete Resurfacer. The asphalt side will have to be top-coated with a suitable asphalt coating.
The number of bags required will depend on the depth of placement. For an area of 120 square feet, you will need 16-2/3 80-pound bags per inch of placement. For example, if you are using common 2x4” lumber, the thickness will be 3-1/2”, so you will need 59 80-pound bags. Yields will vary with waste, uneven subgrade, etc.
Are you nuts?? Order the concrete from a materials yard. Otherwise reserve your spot at the funeral home because you'll die from exhaustion.
The The Home Depot website chart is in error. QUIKRETE will work with The Home Depot to clarify the volume calculations.
QUIKRETE® Crack Resistant Concrete Mix is normal setting; it will typically begin to stiffen after 60-90 minutes and will be '‘thumbprint hard’ after 4-6 hours. The product can be mixed in any non-absorptive container.
Well #1. You didn't mention how wide the area is. That'll make a HUGE difference, but just as a reference, I used 8, 50lb bags to do a 14'L x 19"w x 3d" "dip" at my driveway. Consider a couple things. I made my mix pretty thick because I didn't use a form to pour it into. I went from thick to thin on the edges. If you're using a form and it's a consistant 4" depth, you'll probably follow the liquid measurement directions and the coverage might change just a tad. But, I'd say anywhere from 8-10 bags. But, to be safe, go ahead and get 12 because you can either return unused, or like me, find something to do with it. I made stepping stones with whatever was left over. Hope this helps. Good luck!
