摘要
在国内外文献调研的基础上,分析冻融环境中,单一因素条件下单掺与混掺纤维对混凝土抗冻性能的微观增强机理、宏观抗冻性能及影响因素,并对多因素(冻融与氯盐、荷载、高温、干湿循环等)耦合作用下不同纤维对混凝土抗冻性能的影响进行了归纳与探讨,得出结论及展望,为纤维混凝土的进一步研究和应用提供基础。
On the basis of literature research at home and abroad,this paper analyzes the microscopic enhancement mechanism,macroscopic frost resistance and influencing factors of single-doped and mixed fibers on the frost resistance of concrete under the condition of single factor in the freeze-thaw environment,and summarizes and discusses the effects of different fibers on the frost resistance of concrete under the coupling of multiple factors(freeze-thaw and chloride salt,load,high temperature,dry-wet cycle,etc.).draws conclusions and prospects,it provides a basis for further research and application of fiber reinforced concrete.
