Study on the Hydraulic Performance of Concrete Reinforced by CaCO 3 Modified Polypropylene Fiber

In this paper, the concrete were reinforced by CaCO3 modified PP fiber. The freeze-thaw resistance, anti-permeability and anti-erosion performances of the concrete were studied. The results indicated that CaCO3 , modified PP fiber played a significant role on reinforcement of concrete due to improvement of its density and hydrophilic property. Moreover, freeze-thaw resistance, anti-permeability and anti-erosion performances were greatly improved. Impermeability level of the modified concrete was beyond W8, and antierosion performance was improved by 33%~87%.
