Description

technical field

[0001] The invention relates to a building material, in particular to a silicon-aluminum polymer material, and also relates to a preparation method of the silicon-aluminum polymer material. Background technique

[0002] In the field of material technology development, the development of materials and preparation technologies with low energy resource consumption, low environmental load, and significant energy-saving and emission-reduction effects has attracted much attention. Silica-alumina polymer materials mainly composed of geopolymer cement and alkali-activated cement are such materials with low energy resources and environmental load. Compared with Portland cement, this material has the characteristics of using industrial waste and low synthesis temperature in the preparation process, and has strong advantages in performance. special advantage. Therefore, domestic and foreign are currently keen on the research and development of new technologies for sil...
