Study of Reinforced Concrete Correlation Performance by Blended High Elastic Modulus Polypropylene Fibers
In this study,C40 concrete was reinforced with blended high elastic modulus polypropylene fibers.Concrete working performance was test.Mechanical properties such as flexural strength and compressive strength were tested.Drying shrinkage test,plastic shrinkage test,and concrete ring test were performed to evaluate the cracking resistance of fiber reinforced concrete.The results showed that the flexural strength and compressive strength of concrete can be improved with the incorporation of polypropylene fibers.The results of drying shrink-age,plastic shrinkage,and concrete rings tests showed that the cracking risk can be significantly reduced.
