Situation 2. You will be designing the form work for a concrete wall that is to be 92 feet long x
12 inches thick x 6 1/2 feet high. The following apply to this problem:
You will have one M919 mobile mixer with a 27-cubic-foot capacity. The mixer has
a 1-cubic-yard batch cycle for every 4 minutes.
The concrete temperature is expected to be 50F.
The materials available are: 5/8-inch-plywood sheathing, 2- x 4-inch lumber for
studs, 4- x 4-inch lumber for double wales, and No. 9 wire for ties.
Determine the total mixer output (in cubic FPH) if the mixer capacity is 27 cubic feet
(1 cubic yard) with a batching time of 4 minutes and is operating for 1 hour.
Determine the plan area (in square feet) for a concrete wall form that is 92 feet long x
12 inches thick x 6 1/2 feet high.
Determine the rate of placing (in FPH).
