Is concrete wrong in tensile strength?

Concrete is indeed commonly misunderstood regarding its tensile strength. While it is true that concrete excels in compressive strength, it is relatively weak in tension. This characteristic is a fundamental property of concrete as a material. It can withstand considerable compressive forces but tends to crack under tension unless reinforced.

The correct answer indicates that the statement about concrete being 'wrong' in tensile strength is false; instead, it highlights that concrete's nature is to have low tensile strength, necessitating the use of reinforcement materials like steel rebar or fibers. These reinforcements enhance its ability to perform in structures, taking advantage of concrete's strength in compression while compensating for its limitations in tension.

The other options suggest potential conditions under which concrete might exhibit different tensile strength characteristics or imply ambiguity. However, the fundamental property of concrete remains consistent regardless of type or installation circumstances. Understanding this trait is crucial for effective application in engineering and construction practices.
