地质聚合物水泥的研究进展

Research Progress of Geopolymer Cement

地质聚合物水泥是一种环境友好型的绿色建材,以资源丰富的偏高岭土或来源广泛的高硅铝低钙工业固废为前驱体,并可掺入多种其他固废与化学试剂进行性能调节,具有良好的可控性。其力学性能、工作性能、耐久性能与硅酸盐水泥相比具有较大优势,具有广阔的应用前景,是未来替代硅酸盐水泥的最佳材料之一。本文综述了国内外关于地质聚合物水泥的前驱体材料、反应机理、力学性能、工作性能与耐久性能等方面的研究进展,讨论了地质聚合物水泥现在所面临的问题与未来的发展前景。

Geopolymer cement is a kind of environment-friendly inorganic cementitious materials.It takes metakaolin rich in resources or industrial solid waste with high silicon,aluminum and low calcium as precursors.And it can be mixed with a variety of other solid wastes and chemical agents to adjust the performance,with good controllability.Compared with Portland cement,its mechanical properties,working performance and durability have great advantages.It is one of the best materials to replace Portland cement in the future.This paper reviewed the research progress of geopolymer cement at home and abroad in the aspects of precursor materials,reaction mechanism,mechanical properties,working performance and durability,and discussed the current problems and future development prospects of geopolymer cement.
