In comparison, which is stronger: concrete's compressive strength or tensile strength?

• A. Tensile is better than compressive
• B. Compressive is better than tensile
• C. Both have equal strength
• D. Neither has significant strength

Answer: (B)

Concrete is significantly stronger in compressive strength than in tensile strength, which is why the correct answer is that compressive strength is better than tensile strength.

Compressive strength refers to the ability of a material to withstand axial loads that push or pull it apart. Concrete is designed to bear heavy loads, particularly in structures like buildings and bridges. This characteristic makes concrete an excellent choice for applications that experience loads from above.

On the other hand, tensile strength is the capacity of a material to withstand tension, or pulling forces. Concrete has relatively low tensile strength, which is why it can crack or fail under tensile stresses. To mitigate this weakness, materials such as steel reinforcement bars (rebar) are often used in concrete construction, essentially combining the compressive strength of concrete with the tensile strength of steel to create a material that performs well under both types of stress.

This understanding of concrete's properties is fundamental in the field of construction and engineering, highlighting the importance of using concrete in ways that take advantage of its compressive strength while compensating for its weaker tensile capability.
