摘要:
根据恒温条件下饱和盐水溶液控制的恒定相对湿度,测试了苏州吴江地区近现代2种青砖的等温吸湿曲线.比较了不同样砖、不同年代青砖等温吸湿曲线的差异性,给出了平衡含湿量随相对湿度变化的拟合公式.结果表明:在7%~92%的相对湿度环境中,苏州清末青砖的平衡含湿量在2.84~27.65 g/kg之间,20世纪80年代青砖的平衡含湿量在1.45~10.14 g/kg之间,苏州清末青砖的吸湿量是苏州20世纪80年代青砖的3倍以上.得到的公式及数据可应用于历史建筑砖墙“酥碱”程度的量化确定,并为研究中国传统建筑性能劣化机理及砖构建筑热湿耦合分析提供了基础数据支撑.
Abstract:
Based on constant relative humidity from the saturated salt-water solution under isothermal conditions, the isothermal sorption curves of early modern and modern bricks in Wujiang(Suzhou, China)are measured. The sorption property differences of various samples at different ages are compared, and their fitting formulae of the equilibrium moisture content of grey bricks changing with relative humidity are presented. The results indicate that, with the relative humidity ranging from 7% to 92%, the equilibrium moisture contents of the late Qing grey bricks are between 2.84 and 27.65 g/kg and those of the 1980s grey bricks are between 1.45 and 10.14 g/kg. The equilibrium moisture content of the late Qing grey bricks is about three times that of the 1980s grey bricks. The experimental data and formula can be applied to the quantitative analysis of the efflorescence of the historical brick wall, and provide basic data for the further study on the performance degradation mechanism of Chinese traditional architecture and the dynamical moisture characteristics of the building envelopes.
