In this study, an improved random aggregate adding method was used to develop a microscopic model of glazed hollow bead insulation concrete (GHBIC), and the model’s effectiveness was verified through a test. In addition, the heat transfer performance of GHBIC was also studied using the model. The effect of shape, volume fraction, and gradation of coarse aggregate as well as the volume fraction and gradation of glazed hollow bead on the effective thermal conductivity of this concrete was studied. The results show that the glazed hollow bead effectively blocked the heat flow channel of GHBIC. The smaller the particle size and the higher the volume, the blocking effect is more obvious. Finally, considering the fineness of glazed hollow bead, a mathematical model for the thermal conductivity of GHBIC was established.

在这项研究中，一种改进的随机骨料添加方法被用于开发釉面空心珠保温混凝土（GHBIC）的微观模型，并通过测试验证了该模型的有效性。此外，还使用该模型研究了GHBIC的传热性能。研究了粗骨料的形状，体积分数和等级，以及空心玻璃珠的体积分数和等级对这种混凝土有效导热率的影响。结果表明，釉面空心珠有效地阻塞了GHBIC的热流通道。粒径越小且体积越大，阻滞效果越明显。最后，考虑到釉面空心珠的细度，建立了GHBIC导热系数的数学模型。
