Question

Concrete is strong in tension but weak in compression.

(a) True

(b) False

I had been asked this question in a job interview.

This question is from Analysis of Rates of Cement Concrete in section Analysis of Rates of Civil Engineering Drawing

Answer 1

Correct choice is (b) False

To explain: Concrete is strong in compression but weak in tension. For some purposes it needs to be reinforced with steel rods. Reinforced concrete buildings can be made to link all the parts together, the foundations, walls, floors and roofs, but concrete construction does not make buildings earthquake-proof.
