摘　　要：以黄土为基料,将水泥与粉煤灰作为凝胶材料制作试样,研究影响生土基梯度复合墙体材料热湿综合性能的各种因素,计算生土基梯度复合墙体材料的导热系数、含湿量以及热湿性能,并将导热系数与含湿量进行归一化处理,实现热湿综合性能的计算,根据计算结果分析生土基梯度复合墙体材料热湿综合性能影响因素。实验结果表明,粉煤灰掺量、含水率、水泥掺量会影响生土基梯度复合墙体材料的热湿综合性能,试验获得生土基梯度复合墙体材料的最优配比为水泥掺量为4%、粉煤灰掺量为15%、含水量为16%。Taking loess as the base material,samples were prepared with cement and fly ash as the gel material,and various factors affecting the thehygothermal comprehensive performance of raw soil based gradient composite wall materials were studied.The thermal conductivity,moisture content and thermal and wet performance of raw soil based gradient composite wall materials were calculated,and the thermal conductivity and moisture content were normalized to achieve the calculation of the hygothermal comprehensive performance.The influencing factors of hygrothermal comprehensive performance of the raw soil-based gradient composite wall material were analyzed according to the calculation results.The experimental results showed that the content of fly ash,water content and cement content affected the thermal and wet comprehensive performance of the raw soil based gradient composite wall material.Through the test,the optimal proportion of the raw soil based gradient composite wall material was finally obtained:the content of cementwas 4%,the content of fly ash was 15%,and the water content was 16%.
