An experimental study on mechanical properties of concrete containing steel and polypropylene fibers at high temperatures

The use of fibers in concrete improves strength, ductility and durability of concrete. Concrete has fireproofing properties, but rebars are the most important concern of reinforced concrete structures in the event of fire outbreak. Therefore, one of the recommendations to reduce these risks is the u...
