Mechanics Performance of High-Performance Concrete with Polypropylene Fibers
The mechanics properties of HPC mixing different dosage and length of polypropylene fiber were investigated in this study. The results showed that the addition of appropriate amount and length of polypropylene fibers in HPC led to an effective improvement in the tensile strength and a little change in the compressive strength of HPC. The pronounced improvement can be attributed to the beneficial effect of polypropylene fiber on HPC by restraining the generation and development of the micro cracks in concrete, enhancing the level of stress and deformation and damage characteristics in HPC, furthermore, extending the durability and safety of concrete structure.
