纤维水泥土耐久性能研究现状

Research Status of Durability of Fiber Cement Soil

对近年来关于纤维改善水泥土耐久性能的研究进展进行综述。分析并总结了纤维种类和纤维掺量对纤维水泥土抗干湿性能、抗冻融性能、抗硫酸盐侵蚀性能及抗渗透性能的影响,发现纤维种类和纤维掺量对水泥土的耐久性能影响较大;分析了干湿循环、冻融循环和硫酸盐溶液侵蚀对水泥土内部结构产生的破坏作用及纤维对水泥土耐久性能的改善机理,并对未来研究方向提出建议。

This paper summarizes the research progress on improving the durability of cement-soil with fiber in recent years.The effects of fiber types and fiber content on the dry-wet resistance,freeze-thaw resistance,sulfate attack resistance and permeability resistance of fiber cement soil are analyzed and summarized.It is found that fiber types and fiber content have great influence on the durability of fiber cement soil.The destructive effects of dry-wet cycle,freeze-thaw cycle and sulfate solution erosion on the internal structure of cement-soil and the improvement mechanism of fiber on the durability of cement-soil are analyzed,and suggestions for future research are put forward.
