As you can see, there are lots of variables to answering the how long is hamburger meat good for question.

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.
Guide to what you can and canât do once your concrete is installed. 1  For the First Two Days â Although your new concrete will become solid fairly quickly, it has little strength and hardness for the first two days. 2  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. However, avoid twisting or skidding shoes on the concrete during that time, and keep bicycles, skateboards, and other toys off the surface.
