Per the source, rough-textured aggregates compared with smooth-textured aggregates develop:
A{'text': 'Higher bond strength in tension', 'label': 'A'}
B{'text': 'Lower bond strength in tension', 'label': 'B'}
C{'text': 'Lower compressive strength always', 'label': 'C'}
D{'text': 'Higher water demand and lower bond', 'label': 'D'}
Answer & Solution
Correct answer: A. {'text': 'Higher bond strength in tension', 'label': 'A'}
1. §2.2.5: 'It has also been shown by experiments that rough textured aggregates develop higher bond strength in tension than smooth textured aggregates.'
2. Table 2.2 confirms the trend across smooth-rough ratios at varying water/cement ratios.
