Concrete (cement matrix + aggregate stones) is an example of which composite category?
A{'text': 'Laminar composite', 'label': 'B'}
B{'text': 'Cermet', 'label': 'D'}
C{'text': 'Fiber-reinforced composite', 'label': 'A'}
D{'text': 'Particulate composite', 'label': 'C'}
Answer & Solution
Correct answer: D. {'text': 'Particulate composite', 'label': 'C'}
Particles (aggregate stones, sand grains) embedded in a matrix (cement paste) make concrete a PARTICULATE composite. Reinforced concrete adds steel rebar (fiber phase) — making it a hybrid.
