通过对膨珠及其混凝土制品的材性和构性的试验研究表明,膨珠混凝土可以制做具有保温和结构要求的外墙板以及内墙板等构件,用途广泛,为墙体改革开辟了一条新路。因此,在北京市东三环统建住宅工程中,采用了预制膨珠混凝土外墙板;在水电部宿舍工程中,内外墙板都采用了现浇膨珠混凝土和膨珠页岩陶粒混凝土。由于这种新材料首次用于工程实践,缺乏经验,现仅就工程中应用情况和一些粗浅体会介绍如下。一、膨珠混凝土外墙板生产
Through experimental research on the properties and conformation of expanded beads and their concrete products, it has been shown that expanded concrete can be used to make exterior wallboards and interior wallboards that require thermal insulation and structural requirements. They have a wide range of uses and have opened up the wall reforms. A new road. Therefore, in the Dongsanhuan unified residential project in Beijing, prefabricated expanded-bead concrete exterior wallboard was used; in the Ministry of Water and Electricity Ministry dormitory projects, in-situ concrete and expanded-bead shale ceramsite concrete were used for both internal and external wallboards. . Because this new material was used for engineering practice for the first time and lacked experience, it is only used in the application of the project and some brief introductions are as follows. I. Production of expanded concrete exterior wall panels
