轻集料砼小型空心砌块（以下简称小砌块）具有轻质、高强、保温隔热性能好、抗震性能好、生产效率高、生产成本低及便于施工等一系列优点。因此，国外一些发达国家早在本世纪初期就开始大力发展轻集料砼小砌块，并取代了普通粘土砖在房屋建筑围护结构中的应用。至今，美、德、? The lightweight aggregate concrete hollow block (hereinafter referred to as a small block) has a series of advantages such as light weight, high strength, good thermal insulation performance, good seismic performance, high production efficiency, low production cost, and ease of construction. Therefore, some developed countries abroad began to vigorously develop lightweight aggregates and small blocks as early as the beginning of this century, and replaced ordinary clay bricks in the application of building envelopes. So far, the United States, Germany, and?
