STUDY ON THE INFLUENCE OF DIFFERENT TYPES OF POLYPROPYLENE FIBER CONCRETE ON FIRE RESISTANCE
Main article
Abstract
The open flame calcination test method was employed to assess the residual stress of fiber concrete in a study aimed at understanding the fire resistance of fiber concrete mixed with different types of polypropylene fibers, both alone and in combination with steel fibers. The results indicated a significant improvement in the fire resistance of concrete
with the incorporation of fibers. Notably, concrete mixed with polypropylene monofilament fiber and steel fiber (PSCF1) exhibited minimal compressive strength loss, highlighting its superior performance under fire exposure. Among the various types of polypropylene fibers tested, polypropylene monofilament fiber (a) demonstrated better
fire resistance compared to the other two types of polypropylene fibers. This suggests that the specific type of fiber used in the mix plays a crucial role in enhancing the fire resistance properties of concrete. The study underscores the importance of fiber selection in optimizing the fire-resistant capabilities of concrete structures. By incorporating appropriate fibers, the resilience of concrete in high-temperature conditions can be significantly enhanced, which is crucial for the safety and longevity of structures exposed to fire hazards. The findings of this research provide
valuable insights for the construction industry, offering guidance on the use of fiber-reinforced concrete in applications where fire resistance is a critical requirement. Overall, the study contributes to the development of more robust and fire-resistant building materials, potentially leading to safer architectural designs.
