I took a practice quiz and this question was given: What answer do you think is correct?
A decorative concrete floor has been poured, but the structural engineer has expressed concern about the bearing capacity of the slab. What test should be done to test the strength of the concrete without damaging the floor?
A) K-slump test
B) Cylinder test
C) Core cylinder test
D) Impact hammer test
E) Kelly ball test
I selected C, but the correct answer was D.
I've had core cylinders taken from numerous projects to verify pours. It's taken typically in out of the way places obviously, so it doesn't damage any visible floor areas (chases, etc.)
I would think that the impact hammer test would damage the surrounding floor area. Do you agree?
