摘　　要：以生土建筑材料作为研究对象,利用水泥、石灰、矿渣、粉煤灰和石膏对生土建筑材料进行改性,研究生土基改性建筑材料的力学性能、热性能和湿性能,建立生土基改性建筑材料的综合力-热-湿性能评价体系.结果表明,在最优含水率13%下,生土基改性建筑材料的力学性能大幅提高,石膏/生土建筑材料具有较好的保温性能,粉煤灰/生土建筑材料具有较好的湿性能,水泥/生土建筑材料具有最好的综合力-热-湿性能.With raw soil building materials as the research object. Soil building materials were modified by cement, lime, gypsum, fly ash and slag, were studied on mechanical property, humidity property and thermal property of raw soil-based modified building materials to establish the comprehensive force-thermal-humidity performance evaluation system. Results showed that while optimum moisture content is 13% , mechanical property of raw soil- based modified building materials increased efficiently. Gypsum/raw soil building materials have good thermal insulation property, fly ash/raw soil building materials have good humidity property; and cement/raw soil building materials have the best comprehensive force-thermal-humidity performance.
