Per §7.6.1, in the standard determination of the Modulus of Elasticity the cylindrical concrete specimen used has dimensions of:
A{'text': '100 mm diameter and 200 mm height', 'label': 'A'}
B{'text': '150 mm diameter and 300 mm height', 'label': 'B'}
C{'text': '200 mm diameter and 400 mm height', 'label': 'C'}
D{'text': '300 mm diameter and 600 mm height', 'label': 'D'}
Answer & Solution
Correct answer: B. {'text': '150 mm diameter and 300 mm height', 'label': 'B'}
1. §7.6.1 reads: 'A cylindrical concrete specimen of 150 mm diameter and 300 mm height is subjected to uniaxial compression.'
2. Stress is computed from load/area and strain from a dial gauge fixed to the specimen.
