摘要
地质聚合物是近年来新发展起来的一种新型无机非金属胶凝材料,综合性能优于普通硅酸盐水泥。制备地质聚合物的原材料主要为铝硅酸盐和碱激发剂,许多工业固体废弃物中含有大量铝硅酸盐。本文主要论述了以工业固体废弃物为原材料制备地质聚合物的原理,提出了原材料的硅氧四面体结构在很大程度上影响着地质聚合物性能的观点。
Geopolymer is a new inorganic nonmetallic cementing material coming in recent years,its properties are better than those of Portland cement. The raw materials of geopolymer are mainly aluminosilicate minerals and alkali-activators,and many industrial slags are rich in aluminosilicate minerals,so some industrial slags can be used to produce geopolymer. This paper mainly discusses the effect of raw materials on the properties of geopolymer,and points out that the structure of silicon-oxygen tetrahedron in the raw materials may influence the properties of geopolymer to a certain extent.
