A wall has a height of 12 ft. the rate of filling is 4 ft/hr. Concrete slump is 4 inches. The temperature of the concrete at placement is 70 F and the concrete will be vibrated internally. a) What is the maximum form pressure in psf? b) If everything is the same as above but the concrete slump is 10 inches and the rate of placement increases to 8 ft/hr., what is the maximum form pressure in psf?
