Questions & Answers
Nominal temperature for quick setting
Asked by Curious February 4, 2021Temperature should be on the bag. Usually 50-90 as I recall.
I need to make a wall under a fence that's 1.5 ft deep and 4 inches wide and 140 ft long. how much do I need?
Asked by ronnie January 18, 2021I calculate you are wanting to pour 1680 cubic inches or 70 cubic feet. A bag has roughly .375 cubic feet in it so that would equal 186.6667 if you have no loss so should be able to pour with 190 to 200 bags. Hope this helps. 18 x 4 x 1680 = 120,960 cubic inches 120,960 / 1730 = 69.9 cubic feet 70 cubic feet / .375 cubic feet = 186.666667 bags
I am pouring footings for a deck extending out over the water. Can this be poured into a form th...
Asked by Wayne January 17, 2021I doubt that you'd be successful as the water to concrete mix ratio would be way off. The mix would of course displace the water but the strength of the concrete would be significantly reduced. Get long footing forms that can go all the way to the bottom and drive them into the dirt and try pumping the water out. The tubes will need to be strong enough to withstand the head pressure. The deeper the water the stronger the tube/form will need to be. good luck.
can i use this to build a water feature for my garden?
Asked by vick January 11, 2021You can. It does set up pretty fast. If you are working with a few bags you should be fine. If it's a bigger project you may want to use a mixer or use the regular concrete mix.

Asked by michael January 10, 2021Those measurements give you about 5.33 cubic feet to fill. Each bag is about 0.35 cubic feet so you would need 5.33 ft3/0.35 ft3/bag = 15.22 bags. Go with 16 better to have more than not enough.
