What type of strength is concrete primarily relied upon for?

• A. Flexural
• B. Tensile
• C. Compressive
• D. Shear

Answer: (C)

Concrete is primarily relied upon for its compressive strength, which is its ability to withstand axial loads that push or pull equally on all sides of an object. This property makes concrete ideal for construction applications such as columns, slabs, and beams, where structures must carry significant loads without collapsing. Concrete’s compressive strength is typically much higher than its tensile strength, meaning it can handle substantial pressure but is susceptible to cracking under tension.

In scenarios where concrete is used, it is usually reinforced with steel to improve its tensile strength; this combination helps to mitigate cracking and improve performance under various types of stress. Therefore, the primary characteristic that makes concrete a preferred construction material is its compressive strength, which is crucial for the stability and durability of buildings and infrastructures.
