This compression system is a very handy invention, especially for Web users, because it lets you reduce the overall number of bits and bytes in a file so it can be transmitted faster over slower Internet connections, or take up less space on a disk.
Concrete hardens to 600PSI (Minimum) after 24 hours. This means that 5 three grown men could all stand on a pogo stick (if that were possible) who's base covers 1 square inch without harming the concrete. You walking with shoes on exert about 10 PSI, well below anything that could damage the new pour.
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?
