As you can see, there are lots of variables to answering the how long is hamburger meat good for question. Raw hamburger meat (ground beef) is much more perishable than other cuts of beef and will keep in the refrigerator for only 1 to 2 days. Cooked hamburger meat will keep 3 to 4 days in the refrigerator.
Re: Poured side walk/steps, how long to leave forms? I strip the forms 24 hours later, but am careful not to damage the new concrete. It will still be very soft and with crumble if you put too much force on the edges. Usually concrete will harden withing 30 days to the point where it is considered cured.
Add your answer. How long does it take for cement/concrete to dry? I had a slab leak in my kitchen. A plumber came to my home and had to jack hammer a hole in the floor to get to the leak, after the repair was made he covered up the hole with cement/concrete. How long before we can actually walk on the area? I'm afraid to walk on the area if it is not strong enough, should we wait for 28 days?
