B{'text': '1947', 'label': 'B'}
C{'text': '1962', 'label': 'C'}
D{'text': '1985', 'label': 'D'}
Answer & Solution
Correct answer: B. {'text': '1947', 'label': 'B'}
1. §5.4.3: 'The compacting factor test was developed in Great Britain in 1947. It is claimed to be the most efficient tests for measuring the workability of concrete.'
2. It is particularly useful for mixes of very low workability that the slump test cannot discriminate.
