摘　　要：混凝土小型空心砌块是替代传统实心黏土砖的主要新型墙体材料产品之一,其热工性能对墙体节能影响较大。对广西市场上常用的4种混凝土小型空心砌块进行了大量的相关性能测试,主要针对砌块干密度及其所构筑的墙体构件的热工性能,从而探讨两种性能参数之间的相关性,得到了较为可靠的比对系统,同时对比了不同种类的空心砌块之间的差别,总结各自优势,为墙改节能奠定基础。As one of the new type of wall materials replacing the traditional solid brick wall, the thermal performance of concrete small hollow blocks has a greater impact on the energy efficiency of the external wall. A large number of relevant performance tests were carried out for the four types of concrete small hollow blocks commonly used in Guangxi, mainly focused on the dry density and the thermal performance of the hollow block wall unit. Then the correlation between the two performance parameters was analyzed, a reliable comparison system was established, and the differences of various types of hollow blocks and their advantages were also summarized. The results could lay the foundation for the energy-saving wall.
