近年来泡沫混凝土作为一种无机保温材料倍受关注,然而关于泡沫混凝土导热系数模型的研究甚少。本文首先介绍了几种常用的多相复合材料导热系数模型,然后将各种模型用于泡沫混凝土导热系数试验数据验证和研究并进行比较。研究结果表明,文中所提出的导热系数模型适合特定配比的泡沫混凝土,且因其具有两个可调参数而具有很大的应用潜力。 In recent years, foam concrete has attracted much attention as an inorganic thermal insulation material. However, little research has been done on the thermal conductivity model of foam concrete. This paper first introduces several commonly used multi-phase composite thermal conductivity model, and then use a variety of models for thermal conductivity of foam concrete test data validation and research and comparison. The results show that the thermal conductivity model proposed in this paper is suitable for a certain proportion of foam concrete and has great potential for its application with two adjustable parameters.
