Which of the following is NOT a property of concrete?

• A. High Tensile Strength
• B. High Compressive Strength
• C. Durability
• D. Good Fire Resistance

Answer: (A)

Concrete excels under compressive loads, is durable in harsh conditions, and generally resists fire. The reason it isn’t associated with high tensile strength is that plain concrete is relatively weak in tension; it tends to crack when pulled or bent. To carry tensile forces, reinforcement (like steel) is added, creating reinforced concrete that can handle both compression and tension. So, among the options, high tensile strength is not a property of standard concrete, while high compressive strength, durability, and good fire resistance are.
