Acid-resistant geopolymer synthesized from chitosan, metakaolin and blast furnace slag and preparation method thereof
The invention discloses an acid-resistant geopolymer synthesized from chitosan, metakaolin and blast furnace slag and a preparation method thereof. The acid-resistant geopolymer comprises the following raw materials in parts by weight: 200-444 parts of a mixture; 200 to 568.4 parts of sodium silicate; 108 to 432 parts of water; 10 to 80 parts of sodium hydroxide; 15-56 parts of carbide slag; the mixture is a mixture of blast furnace slag and metakaolin, the mass fraction of the metakaolin in the mixture is 40%-70%, and the mass fraction of the blast furnace slag in the mixture is 40%-70%; the composite material further comprises an additive, and the additive comprises chitosan and chitosan fibers. The compressive strength of the geopolymer can be improved, and meanwhile, the acid resistance of the geopolymer can also be improved.
