摘要/Abstract

摘要： 为了研究硫酸盐干湿循环下聚乙烯醇(PVA)纤维废玻璃粉混凝土的耐久性,本文采用两种粒径的废玻璃粉取代混凝土中的部分水泥,同时改变PVA纤维的体积掺量,设计了硫酸盐干湿循环试验,测定了干湿循环后废玻璃粉混凝土的抗压强度和抗弯强度,并利用扫描电子显微镜(SEM)和能谱仪(EDS)探究了PVA纤维废玻璃粉混凝土的微观结构特征,最后基于Weibull函数建立了耐久性退化模型来预测混凝土寿命。结果表明:废玻璃粉粒径为(30,75] μm时抗硫酸盐侵蚀性能较好;PVA纤维对混凝土产生内部裂纹起到了有效的阻碍作用,随着PVA纤维掺量的增加,PVA纤维废玻璃粉混凝土的抗硫酸盐侵蚀性能增强,在PVA纤维掺量为1.0%(体积分数)时抗硫酸盐侵蚀性能最好;建立的耐久性退化模型预测PVA纤维体积掺量为1.0%的废玻璃粉混凝土在硫酸盐溶液环境中干湿循环的最长使用寿命可达224 d。

Abstract: In order to study the durability of polyvinyl alcohol (PVA) fiber waste glass powder concrete under sulfate dry-wet cycle, two kinds of particle size waste glass powder were used to replace part of cement in concrete. At the same time, the volume content of PVA fiber was changed. The sulfate dry-wet cycle test was designed, and compressive strength and flexural strength of waste glass powder concrete after dry-wet cycle were measured. The microstructural characteristics of PVA fiber waste glass powder concrete were explored by SEM and EDS. Finally, the durability degradation model based on the Weibull function was established to predict concrete life. The results indicate that when the particle size of waste glass powder is (30,75] μm, the performance of resisting sulfate corrosion is relatively good. PVA fibers play an effective role in hindering the internal cracks of concrete. With the increase of PVA fiber content, the performance of resisting sulfate corrosion of PVA fiber waste glass powder concrete increases, and it shows the best performance of resisting sulfate corrosion when the PVA fiber content is 1.0% (volume fraction). The durability degradation model predict that the maximum service life of waste glass powder concrete with PVA fiber volume content of 1.0% can reach 224 d under the dry-wet cycle of sulfate solution.

Key words: PVA fiber, waste glass powder concrete, sulfate corrosion, mechanical property, microstructural characteristic, Weibull function
