摘要：理论分析了发泡气体对泡沫混凝土导热系数的影响，并通过试验对理论分析的结果进行了验证。结果表明，发泡气体会影响泡沫混凝土的导热系数，同种胶凝材料制备的相同体积密度的泡沫混凝土，发泡气体的导热系数越低，泡沫混凝土的导热系数也越低，该结论可以为改善泡沫混凝土的导热系数提供参考。

Abstract：The influence of foaming gas on the thermal conductivity of foamed concrete was analyzed theoretically，and the results of theoretical analysis were verified by experiments. The results show that the foaming gas can affect the thermal conductivity of foamed concrete. For foamed concrete of the same bulk density prepared from the same type of cementitious material，the lower the thermal conductivity of the foaming gas，the lower the thermal conductivity of the foamed concrete. This conclusion can provide a direction for improving the thermal conductivity of foamed concrete in the future.
