Temperature 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?

I 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 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?

You 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.

how many bags 4ftx4ftx4inches

Asked by michael January 10, 2021

Answers

Those 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.

i have 8 post holes, 8inches diameter and 44 inches deep. need to know how many i need.

Quickset concrete mix
The yard has a bit of an incline, so I had to stack a row to get the proper level height. The concrete needs to be sifted to get pebbles,etc out. The key is to lightly mist the mix to begin the hardening process.. definitely would use again

I used this to make stepping stones and compared it to the vinyl patch mix : both will work. The Quickcrete provides a more natural, pebbly background . If you work fast, you can insert shells and mosaic pieces, but be ready with your materials because it hardens quickly! It's just a preference, but if you want a more rugged look, this is your medium and more slip proof as well. Just mix up what you are immediately going to use, and have a little extra mold ready in case you have extra left over. Have fun !

I love using Quikrete fast setting concrete mix because it does exactly what it says, sets up extremely fast. I can pour the Quikrete in the hole as is and pour in a little water on top, put my dirt in to fill the hole, wait a few minutes as a bag suggest and I’m ready to go. I use the Home Depot curbside pick up so getting the bags into the car was easy. I was able to set my 4 x 4 post and add my solar lights on top in a matter of minutes.
