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.
Concrete gets progressively harder over time its called curing. However it depends on several thing like temperature and moisture. You can typically walk on concrete the next day but it can be prone to scratching. I generally have my customers wait two days to walk on it and 7-10 days to drive.In summer time on hot days concrete can cure to fast and crack within hours.oncrete gets progressively harder over time its called curing.
