温湿度对轻质烧结页岩多孔砖墙体材料导热系数的影响

摘要

采用控制变量法研究温湿度对轻质烧结页岩多孔砖及其墙体热工性能的影响.测试其在不同环境温度下的导热系数,拟合出各砌体材料的温度-导热系数曲线及相关表达式;测试在室温条件下(25℃)不同含水率的各砌体材料的导热系数,并将理论值与实测值相比较,拟合出相关曲线及表达式.%The impact of temperature and humidity on the thermal properties of lightweight sintered shale brick and its wall material was studied by the control variable method. Testing its thermal conductivity under different environmental temperature readings,and fitting out the masonry material temperature-thermal conductivity curve and get the related expression. Test the ther-mal conductivity of various masonry materials of different moisture contents at room temperature (usually 25℃),compare the actual values with the theoretical calculated value to fit out the related curve and expression.
