There are also some engineers think polypropylene fiber is a priority to improve the durability of concrete information. If the anti-fatigue function as a target of a road bridge durability of concrete, of course, the above understanding is correct. In addition, the effect of improving the function of polypropylene fiber concrete also includes: concrete bleeding after cuts, the quality of the appearance of the concrete is improved, so that the wear resistance of concrete to be progressive function and effect can be significantly improved crack resistance of concrete The anti-leakage function. The durability of polypropylene fiber to other goals, such as anti-permeability of concrete, frost and salt freezing resistance, chemical resistance, also has no impact unlucky, but the degree of improvement needs further discussion.

    After the above analysis concluded that:
① polypropylene fibers can eliminate or reduce the number of fractured concrete natively and standards, this effect is not only useful to impede the onset of plasticity of concrete cracking, the function of hardened concrete is also very beneficial.
② polypropylene fibers although not hardened concrete quasi-static load strength and significant progress, but progress through concrete impact and fatigue can make use of the function function is improved concrete bridge deck pavement.
③ because the difference in the fiber fineness modulus of elasticity, and other functions, the polypropylene fiber and steel fiber concrete impact on the function and mechanism of action are not the same, both have their own strengths.
④ because reason experimental evaluation approaches, indoor small specimens can show abundant use of polypropylene fiber effect works in practice, resulting in the use of polypropylene fibers practice contempt action.

    The direction of future research should be a composite effect of the compound effect of polypropylene fibers and steel fibers for high strength and high impact polypropylene fiber function concrete features, polypropylene fibers and silica fume or fly ash and other active admixture, as well as fiber Measures such as the use of the role of assessment. Discussion of fiber reinforced concrete measures should also pay more attention to the role of investigating the use of engineering practice, rather than simply through indoor small specimens functional assessment.

    Because polypropylene fiber is the result of the elimination or reduction of the number of existing fractures and standards to improve the quality of concrete to complete the concrete application of functional improvement, therefore, can be incorporated into the polypropylene fiber as an important way to complete the function of high concrete to discuss .
