The field condition is: the work should be released only if the team addresses that heat and wind may cause rapid slump loss and surface drying. Which placement control best matches the condition?
Correct Answer
D) Coordinate cooling shade timely discharge and curing
cooling shade timely discharge and curing best matches the stated condition. The other choices are real construction options in the same family, but they fit different field conditions.
Why This Is the Correct Answer
cooling shade timely discharge and curing best matches the stated condition. The other choices are real construction options in the same family, but they fit different field conditions.
Why the Other Options Are Wrong
Option A: Coordinate set-retarding admixture as approved
Coordinate set-retarding admixture as approved may relate to another site control, but it does not remove or guard the hot weather concrete controls exposure being tested.
Option B: Coordinate evaporation reducer during finishing
Coordinate evaporation reducer during finishing may relate to another site control, but it does not remove or guard the hot weather concrete controls exposure being tested.
Option C: Coordinate windbreaks and sunshades at the placement
Coordinate windbreaks and sunshades at the placement may relate to another site control, but it does not remove or guard the hot weather concrete controls exposure being tested.
Memory Technique
Name the harm before the guard; set-retarding, admixture, approved cannot stand in for Manager Checking.
Reference Hint
Open-book path: tab Principles and Practices of Commercial Construction, 10th Edition to Concrete placement methods; hot-weather handling and curing; verify the construction method, material selection, equipment choice, or work sequence that fits the field condition.
