由石家庄市建材二厂承担的“利用加气混凝土碎块研制屋面保温材料”科研项目于90年元月6日在石家庄市通过了省级技术鉴定。这项目是利用粉煤灰加气混凝土碎块的轻质、保温等特性,经过简单加工使其成为新型屋面保温材料。利用这种材料可使施工方便并可降低工程造价。经测试,使用它做屋面保温材料的建筑 The research project of “Using Aerated Concrete Fragments to Develop Roof Insulation Materials” undertaken by Shijiazhuang No. 2 Building Materials Factory passed provincial technical appraisal in Shijiazhuang City on January 6th, 1990. This project is the use of fly ash aerated concrete pieces of lightweight, thermal insulation and other characteristics, after a simple process to become a new type of roof insulation materials. The use of this material can facilitate construction and reduce the cost of the project. Tested to use it for roofing insulation construction
