Question 1
Which of the following construction materials have high compressive strength and are suitable for structural use?
Correct Answer Explanation
All three materials exhibit high compressive strength suitable for construction:
- Concrete: compressive strength typically 20–60 MPa (higher with reinforcement)
- Granite: unconfined compressive strength 130–250 MPa — excellent dimension stone
- Steel: yield strength 250–690 MPa in both compression and tension
