Effect of fire exposure on mechanical properties of normal strength concrete: An overview

Concrete is widely utilized as a construction material owing to its desirable mechanical properties, which include high compressive strength, durability, hardness, workability, and fire resistance. In addition, concrete is often utilized as a structural element in buildings where fire resistance is...
