Zhongtian K8003 polypropylene fiber is the lightest among all chemical fibers, with a density of (0.90~0.92) g/cm3. It has advantages such as high strength, good toughness, chemical resistance, and microbial resistance, as well as low cost. Polypropylene reinforced with glass fiber or modified with rubber and SBS is widely used in the production of construction templates. Foamed polypropylene can be used to make decorative materials. [6] When an earthquake occurs, the failure mode of polypropylene fiber reinforced ceramic aggregate concrete is plastic failure, with no debris peeling off.
