摘要：对当前国内外混凝土耐久性评价方法进行了综合评述，并基于混凝土抗渗性与耐久性之间的密切关系建立了“基于抗渗性的纤维混凝土耐久性综合评价体系”。基于这一评价体系,结合纤维混凝土的特点建立了“基于抗渗性的纤维混凝土耐久性评价体系模型”。通过对聚丙烯纤维混凝土、玄武岩纤维混凝土以及玄武岩-聚丙烯混杂纤维混凝土的抗水渗性、抗冻融性和抗硫酸盐腐蚀性进行试验研究，对各系列纤维混凝土抗渗性指标D1与抗冻融性指标D2、抗硫酸盐腐蚀性指标D3关系进行拟合,并得到了基于抗渗性的玄武岩-聚丙烯混杂纤维混凝土耐久性评价模型，进一步验证了“基于抗渗性的纤维混凝土耐久性评价体系模型”的合理性。 Abstract: The methods for evaluating the durability of concrete at home and abroad were reviewed. The "integrated evaluation system for durability of concrete based on the permeability" was established based on the close relationship between concrete permeability and durability. Based on the evaluation system, the "integrated evaluation system for durability of fiber concrete based on the permeability" was established combined with characters of fiber concrete. Experimental researches were carried out on resistance to water permeability, freeze-thaw resistance and corrosion resistance to sulphate of polypropylene fiber reinforced concrete, basalt fiber reinforced concrete and basalt - polypropylene fiber reinforced concrete; through the experimental data analysis, the relationships between water resistance indexes D1 with resistance to freezing and thawing indexes D2 and sulphate resisting corrosion indexes D3 of fiber reinforced concrete were simulated, and the integrated evaluation system for durability of basalt-polypropylene fiber reinforced concrete based on the permeability was gotten, and then the rationality of " integrated evaluation system for durability of fiber reinforced concrete based on the permeability" was verified.

Abstract: The methods for evaluating the durability of concrete at home and abroad were reviewed. The "integrated evaluation system for durability of concrete based on the permeability" was established based on the close relationship between concrete permeability and durability. Based on the evaluation system, the "integrated evaluation system for durability of fiber concrete based on the permeability" was established combined with characters of fiber concrete. Experimental researches were carried out on resistance to water permeability, freeze-thaw resistance and corrosion resistance to sulphate of polypropylene fiber reinforced concrete, basalt fiber reinforced concrete and basalt - polypropylene fiber reinforced concrete; through the experimental data analysis, the relationships between water resistance indexes D1 with resistance to freezing and thawing indexes D2 and sulphate resisting corrosion indexes D3 of fiber reinforced concrete were simulated, and the integrated evaluation system for durability of basalt-polypropylene fiber reinforced concrete based on the permeability was gotten, and then the rationality of " integrated evaluation system for durability of fiber reinforced concrete based on the permeability" was verified.
