摘　　要：通过含水率对轻质烧结页岩砖、保温砂浆、普通砂浆导热系数影响试验和理论分析，并研究含水率对抹灰厚度为10、20mm的普通砂浆和保温砂浆墙体的传热系数影响。提出符合3种墙体材料导热系数与含水率的拟合计算公式，当含水率平均每增加1％时，则1^#、2^#、3^#、4^#墙体的传热系数分别增大1．75％、1．55％、1．65％和1．73％；抹灰厚度每增加10mm，普通砂浆和保温砂浆抹面砌筑的墙体传热系数平均减小0．52％、7．07％。Through test and theoretical analysis about the influence of moisture content on the thermal conductivity of light shale sintered brick,thermal insulation mortar and ordinary mortar, it studies the effects of moisture content on the heat transfer coef fleient of ordinary mortar and insulation mortar wall when plastering thickness are 10 mm and 20 ram. It provides fitting formulas of thermal conductivity and water content rate about three kinds of wall materials,when the moisture content is increased per 1%,wall 1,2,3 and 4 heat transfer coefficiem are increased 1.75%, 1.55%, 1.65% and 1.73%,when plastering thickness is increased each 10 mm, ordinary mortar and insulation mortar masonry wall heat transfer coefficient is reduced by an average of 0.52% and 7.07%.
