Abstract | G eopolymer-based protective coating (GPC) is a new type of inorganic coating with excellent properties and geopolymers as film forming material. However, due to the wide variety of silicon-aluminum materials and activators, the curing mechanism of GPC is complicated, with differences in surface drying time, adhesion strength and erosion resistance. Notably, the environmental temperature and humidity affect these performances. In engineering applications, actual needs and environmental conditions should be considered to optimize the selection of silica-aluminum raw materials, activator types, modulus and dosage, admixture and ratio. At the same time, geopolymers also have some disadvantages, such as high shrinkage, brittle cleavage and carbonation, which also limit its wide application in engineering to a certain extent. This article describes the influence factors of curing film formation of GPC of high calcium, low calcium and noncalcium, analyzes the effects of aluminosilicate material, activator and curing conditions on the surface drying time, adhesion strength and erosion resistance of GPC. This paper indicates the improvement effect of strategies on the performance of GPC to handle the existing problems, such as adding aluminosilicate raw materials, nanoparticles, LDHs and organic polymers. |
