轻质大砖是一种价廉、质优、容重轻、(比普通红砖轻2-6倍)强度高(相当50-150号粘土砖)隔热性能良好(导热系数比粘土砖小3-7倍),体积大、便于机械化施工的新型建筑材料.它既是良好的隔音隔热材料,又能用于承重.我们可以按照需要把它制成砖形,也可以制成管形或板形.用轻质大砖代替粘土砖作墙体材料可以大大减轻建筑物自重,还可以少用很多粘土,解决了生产粘土砖需耗用大量农田与农业生产发生矛盾的问题.这种用途极广的新型建筑材料在全国工农业大跃进声中,已由我建筑工程部建筑科学研究院试制成功了. Lightweight large brick is a cheap, high quality, light weight, (2-6 times lighter than ordinary red brick) high strength (50-150 clay bricks) good thermal insulation (thermal conductivity smaller than clay bricks 3 -7 times), a new type of building material that is large in size and easy to mechanize. It is not only a good sound insulation material but also can be used for load bearing. We can make it into bricks as required, or it can be made into tube or plate. The use of lightweight large bricks instead of clay bricks as wall materials can greatly reduce the weight of the building and can also reduce the use of many clays, which solves the problem of the contradiction between the production of clay bricks and the consumption of large amounts of farmland and agricultural production. Guangda’s new building materials have been successfully tested by the Architectural Science Research Institute of China’s Ministry of Construction.
