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.
Do not drive on the concrete for the first 7 days. Leave the warning tape in place to let delivery vehicles and others know that they need to stay off your concrete. After One Week â After 7 days, itâs OK to drive on your new concrete with normal passenger vehicles.
