In the context of tensile strength, which of the following statements about concrete is correct?
- AConcrete has high tensile strength but low compressive strength
- BConcrete exhibits low tensile strength compared to its compressive strengthCorrect
- CConcrete has equal tensile and compressive strength
- DConcrete does not have tensile strength
Solution
Concept
Tensile versus compressive strength
Formula
ft ≈ 0.7√fck
Step-by-step solution
1. Tensile strength is about 10% of compressive strength.
Explanation
Concrete is strong in compression and weak in tension.
Why the other options are wrong
The other statements are false.
Shortcut
Tension ≈ 1/10 compression.
Correct answer: B) Concrete exhibits low tensile strength compared to its compressive strength
