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.
Many homeowners keep a constant eye on their project during this time. Falling leaves, tree sap, and wild animals like squirrels, crows, and other birds can also scar the surface, especially in the first 24 hours. For the Rest of the First Week â After two days, you can feel free to walk on your new concrete. Itâs tough enough at that time to resist scars from walking.
