Concrete has excellent what strength?

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

Answer: (A)

Concrete is celebrated for its ability to withstand heavy loads when squeezed. The cement paste and aggregates form a dense, rigid matrix that resist crushing, so they carry most of the load in a compressive situation. This high compressive strength is a defining property of concrete and is why it’s used for foundations, columns, and walls. In contrast, concrete is relatively weak in tension; it tends to crack when pulled apart, which is why reinforcing steel is added to take tensile forces. Flexural and shear strengths matter, but they don’t match the exceptional performance concrete shows under compression. That makes compressive strength the best description of concrete’s standout strength.
