去年10月下旬建材部科教局在上海召开人造轻骨料科研课题讨论会,初步编制出1979至1985年科研课题计划。今后六年的奋斗目标是:人造轻骨料用于墙体中,要求其混凝土容重不超过1000公斤/米~3,强度达100号;用于承重构件中,要求其混凝土容重不超过1600公斤/米~3,强度达400～500号。原料要因地制宜,就地取材,以利废为主。燃料以用煤为主。配合框架轻板建筑体系和年产10万立米陶粒厂
In late October last year, the Science and Education Bureau of the Ministry of Building Materials held a seminar on research projects for man-made lightweight aggregates in Shanghai and initially prepared a research project plan for 1979-1985. The goal of the next six years of struggle is: artificial lightweight aggregate used in the wall, its concrete bulk density does not exceed 1000 kg / m ~ 3, the strength of 100; used in load-bearing components, the concrete bulk density of not more than 1600 kg / M ~ 3, the strength of 400 to 500. Raw materials should be adapted to local conditions and locally sourced materials to facilitate waste disposal. The main fuel is coal. Cooperate with framework light board building system and annual output of 100,000 cubic meters ceramic factory
