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.
Conventional concrete setting times are bit more subjective. Assuming that optimum temperatures are present during pouring and setting, you can *possibly* walk it in 24 hours, but gently. I like to wait 48 hours to be on the safe side. It will take 7 days to reach 2,500 lbs.he only stupid question is the one not asked. Not only can you get DIY advice at the Chatroom but a bit of Chinese philosophy as well. ****************************. The fast setting concrete answer is easy. You can walk it in 2 hours and set heavy objects in 4 hours.
