Background
The geopolymer is a gelled material which is obtained by taking silicon-aluminum solid waste as a main raw material through a chemical alkali excitation mode. As the geopolymer has the advantages of high mechanical strength, corrosion resistance, low carbon, environmental protection and the like, the geopolymer is widely considered as a green cementing material which can replace or partially replace cement. Through a physical foaming or chemical foaming mode, bubbles can be introduced into a geopolymer system to prepare the foamed geopolymer with a porous structure. The foamed geopolymer is loose and porous, so that the foamed geopolymer is widely used for research and application of building functional materials such as light partition wall materials, heat insulation materials, sound insulation and noise reduction materials and the like. However, the use of foamed geopolymers in aqueous environments has not been effectively exploited, mainly because: 1) the geopolymer system is over-alkaline and contains a large amount of free alkali, so that the geopolymer system is not water-resistant and is easy to cause alkali loss and efflorescence phenomenon when meeting water; 2) the pore structure of foamed geopolymers is difficult to control, and in particular, pore connectivity is difficult to achieve. Therefore, overcoming the two problems has important significance for application in the water environment of the foamed geopolymer and widening the application field of the foamed geopolymer.
