Density Calculation
CORRECT|ANSWER
(Mc&m-Mm)/Vm=Density in lb/ft³
Density Calculation (example)
CORRECT|ANSWER
(90.2 lb - 19.1 lb) / 0.500 ft³ = 142.2 lb/ft³
Concrete Yield
CORRECT|ANSWER
Total mass of all materials batched (lb) /
Density of concrete (lb/ft³) x 27 (ft³/yd)
Concrete Yield (example)
CORRECT|ANSWER
34,700 lb /
141.9 lb/ft³ x 27 ft³/yd = 9.06 yd³
Relative Yield
CORRECT|ANSWER
Actual Yield (yd³) /
Design Yield (yd³) = Relative Yield
