Effect of Different Environments on Durability of PPF Concrete

Abstract:

Different from ordinary Portland cement concrete, the Polypropylene Fiber (PPF) concrete is a new type of concrete and is made through mixing PPF into common concrete. To popularize and apply PPF concrete, this paper carried out a series of experimental study on the durability of PPF concrete under chloride environments. In the present study, three chloride environment tests were conducted on PPF concrete with various volume fraction of PPF (0,0.1%,0.3%,0.5%). The scaling of concrete, the chloride penetration in concrete and the microstructure in concrete were determined. The results indicated that the scaled mass and relative dynamic modulus of elasticity loss decrease with the volume of fiber increasing, Cl^- concentration has a much higher content near the sample surface, adding 0.1% PPF into concrete has the perfect resistance of Cl^- penetration. More fibers can delay the development of cracks, but that will reduce the inner density of concrete.
