Question

Compaction factor for a heavily reinforced section with vibration is:

(a) <0.75

(b) 0.75-0.85

(c) 0.85-0.92

(d) >0.92

This question was addressed to me in an interview.

My question is taken from Tests on Concrete topic in portion Building Construction of Basic Civil Engineering

Answer 1

Correct answer is (c) 0.85-0.92

To explain I would say: Compaction factor test is conducted to determine the compaction factor. It has different values required for different purposes. To concrete a heavily reinforced section with vibration it is 0.85-0.92.
