随着建筑工业化的发展,用轻骨料配制成的单一材料轻骨料混凝土外墙板的应用越来越多。它具有工艺简单、生产效率高且便于内外装饰等特点,深受施工单位的欢迎。但在以往的应用中,由于受材料性能、生产工艺及其经济效果等方面的限制,常常选用普通砂做细骨料,致使配制出的轻骨料混凝土(即砂轻混凝土)容重较 With the development of the industrialization of construction, the application of single material lightweight aggregate concrete exterior wall panels made of light aggregates is increasingly applied. It has the characteristics of simple process, high production efficiency and easy internal and external decoration and is welcomed by the construction unit. However, in the past, due to limitations in material properties, production processes, and economic effects, ordinary sand was often used as a fine aggregate, resulting in a lighter-weight aggregate concrete (ie, sand-and-light concrete) having a lower bulk density.
