Calculate the lateral concrete pressure for a wallformwork. The wall is 15′ high, 30′ long and 1′ thick. Concrete will be placed in 2 hours. Cement is type 1 with retarders and is normal weight (150 pcf). Temperature is 80°F, Slump is 6″ and vibration depth is 3′. Calculate minimum and maximum required concrete pressure.
