泡沫混凝土是一种建筑节能材料，具有轻质、保温隔热、隔声、防火耗能等优异性能。通过对外保温、内保温和自保温围护墙体的热工缺陷、传热性能等进行测试，用建筑传热理论分析各类墙体的传热系数、热惰性指标和技术经济特征值，得出：外保温对热桥的阻隔作用大于内保温，泡沫混凝土自保温墙体室内热环境最好；泡沫混凝土蓄热系数大于EPS保温板，自保温墙体的热稳定性好，抵抗外部温度波动的能力强；泡沫混凝土自保温墙体传热性能良好，技术经济特征量较小，具有一定的市场应用前景。

Foam?concrete was a building energy?saving material with many excellent performances such as lightweight, thermal insulation, sound insulation, fire, power consumption. Through testing the thermal defect and heat transfer performance of external?insulation, internal?insulation and self?insulation retaining walls, and analyzing these walls ’ heat transfer coefficient, thermal inertia indicator and eigenvalue on technical and economic with the building heat transfer theory, some conclusions are taken that:the external?insulation’ s barrier?effect for thermal?bridges was greater than internal?insulation, and foam?concrete self?insulation wall had the best indoor thermal?environment;foam?concrete’ s regenerative coefficients were greater than EPS insulation board, self?insulation wall had great thermal stability and resistance to external temperature fluctuations; foam?concrete self?insulation wall had good heat transfer performance, smaller eigenvalue on technical and economic which have a better marketing prospects.
