一、引言砼小型空心砌块（以下简称砼砌块），是我国近年来发展迅猛的一种新型墙体材料，利用砌块代替粘土砖，可以节约能源，保护耕地，充分利用地方资源等，这对于我国这样一个人口众多、土地资源相对贫乏的国家来说，尤其具有重要意义，也是我国目前墙体材料改革一个重要方 I. Introduction Small hollow blocks (hereinafter referred to as “blocks”) are a new type of wall material that has developed rapidly in recent years in China. Using blocks instead of clay bricks can save energy, protect cultivated land, and make full use of local resources. This is particularly important for a country with a large population and relative lack of land resources. It is also an important factor in China’s current reform of wall materials.
