将粉煤灰“免烧砖”的同类制品“粉煤灰小型空心砌块”纳入“新型墙体材料目录”值得商榷

Discussion on the validity of listing the small hollow fly ash block as a new wall materials in the industrial standard

就行业标准《粉煤灰小型空心砌块》技术水平低下进行了讨论;根据中国建筑材料科学研究院水泥所进行的粉煤灰小型空心砌块水化机理试验研究生成的水化产物,对照相关国家标准说明粉煤灰小型空心砌块与"免烧砖"同属耐久性能低劣的非蒸压粉煤灰硅酸盐制品,不能满足建筑工程质量和安全的需要,将给建筑工程留下隐患。因此,将"粉煤灰小型空心砌块"纳入"新型墙体材料目录"值得商榷。

Through an analysis on the amount of fly ash in small hollow fly ash block and the hydrate product in testing hydrate mechanism, the paper puts forward that the small hollow fly ash block can＇t satisfy the demands of the quality and safety for building, so it＇s worth to discuss if the small hollow fly ash block can be listed as a new wall materials in the industrial standard.
