地质聚合物（GP）的许多潜在和实际用途已被列出，例如废物封装，耐火材料，耐火镶板，下水道管道，建筑产品和耐酸涂料[1]。其他拟议的技术用途包括应用于混凝土的防火涂料[2]。如果GP被用作保护涂层或粘合剂，那么了解GP与其他材料的粘合性质是需要的。两种常见的制备GP的方法是将粉煤灰或偏高岭石（MK：加热至10750 ℃使其无定形的高岭石）加入到浓碱溶液中进行反应并随后发生聚合。所产生的GP由无定形至半结晶三维铝硅酸盐网络组成[3]。对于工业应用，使用粉煤灰作为前体提供了优于MK的成本优势。然而，为了理解聚合过程的科学，优选使用后者。
Many potential and actual uses for geopolymers (GPs) have been listed, such as waste encapsulation, refractories, fire resistant paneling, sewer pipes, building products, and acid-resistant coatings [1]. Other proposed technical uses include fire protection coatings as applied to concrete [2]. Understanding the nature of bonding of GPs to other materials is desirable if GPs are to be applied as protective coatings or adhesives.Two common methods of making GPs are to add fly ash or metakaolinite (MK: kaolinite heated to∼ 750◦ C to render it amorphous) to concentrated alkali solutions for reaction and subsequent polymerization to take place. The GPs produced consist of amorphous to semi-crystalline three-dimensional aluminosilicate networks [3]. For industrial applications, the use of fly ash as a precursor gives a cost advantage over MK. However to understand the science of the polymerization process, the use of the latter is preferred.
