yield and air content. After the density is determined, the yield and air content can then be calculated using given formulas. Density (unit weight) is a measure of weight per unit volume and is expressed in lbs/ft³ or kg/m³. The density of fresh concrete is similar to the density of hardened concrete. After the unit weight is determined ...

6. The outside of the density bucket should be cleaned before weighing. (T or F) 7. Concrete with a slump less than 1 inch should be rodded 25 times per layer. (T or F) 8. According to C138, concretes with slumps of 1-3 inches may be compacted with the vibrator or the rod. (T or F) 9. The unit weight bucket must be calibrated at least once a month.
