摘　　要：目前,对于碳纤维水泥基复合材料在常温下的压敏性能,国内外做了大量的研究工作。由于我国的一些地区冬季气温较低,日平均气温在0℃以下,在这种低温环境下,探索碳纤维水泥基复合材料的低温压敏性能有重要意义。本次试验拟研究碳纤维水泥砂浆在0℃以下的压敏性能,比较其与常温下压敏性能的异同,为今后在土木工程结构健康监测的应用打下基础。At present, the pressure-sensitive study of carbon fiber reinforced cement composites at normal temperature,people have done a lot of research work. As daily average temperature in some parts is below 0℃ in winter,in such low-temperature environment ,to explore carbon fiber reinforced cement composites pressure-sensitive properties is significance. This experiment intended to study carbon fiber reinforced cement mortar of pressure-sensitive properties in Celsius below 0℃ ,compared with the normal temperature pressure-sensitive properties of the similarities and differences, establish a basis for future health monitoring of civil engineering structures.
