The geopolymer is an inorganic polymeric aluminosilicate material which is formed by a silica-alumina raw material under the action of an exciting agent through dissolution-monomer reconstruction-polycondensation to form a three-dimensional network framework structure consisting of oxygen atoms shared by silica tetrahedrons and aluminoxy tetrahedrons and has a natural mineral structure in a shell. Compared with the production of ordinary portland cement, the production process of the geopolymer has low energy consumption which is about 30 percent of that of the ordinary portland cement; and the emission of harmful gases is less, CO2The discharge amount is only 9 percent of that of the common Portland cement; meanwhile, industrial waste residues such as fly ash, coal gangue and the like can be greatly utilized. The geopolymer cementing material has the excellent performances of early strength, quick hardening, low permeability, corrosion resistance, good durability and the like, can be applied to the fields of repair, emergency repair, nuclear waste and hazardous substance curing treatment, marine environmental engineering and the like of concrete materials, but has the main problems of high brittleness, easy water loss and cracking during curing and the like. Modification studies have been conducted by the researchers, for example, the patent application No. 201910537921.4 discloses a styrene-acrylic emulsion toughened polymer and a preparation method thereof; the patent application No. 201810203132.2 discloses an epoxy resin toughened metakaolin based polymer and a preparation method thereof; the patent application No. 201611127977.5 discloses a chitosan-modified geopolymer cement; the patent application No. 201910062137.2 discloses an ultra-high toughness geopolymer and a preparation method thereof, wherein a toughening agent is polyvinyl alcohol fiber; and so on. In the above patents or articles, the modifiers used for modifying the geopolymer are all high molecular materials, and the high molecular materials have the defects of easy aging, no high temperature resistance and the like, so that the obtained geopolymer has poor high temperature resistance and mechanical properties; in addition, after the modified geopolymer is hydrated and hardened, a hardened body has more harmful holes with the hole diameter of 50-200 nm, so that the strength is influenced, and the comprehensive performances such as frost resistance, durability and the like are also influencedAnd the popularization and application of geopolymer are restricted.
The whisker is a fiber which is naturally formed or grows in a single crystal form under the condition of artificial control, the diameter of the fiber is in the magnitude of micro-nanometer, the fiber has no defects of grain boundaries, dislocation, cavities and the like, the atomic arrangement is highly ordered, the strength of the fiber is close to the theoretical value of a complete crystal, and the mechanical strength of the fiber is equal to the force between adjacent atoms. The highly oriented structure of the whisker not only enables the whisker to have high strength, high modulus and high elongation, but also has the properties of electricity, light, magnetism, dielectric, electric conduction and super electric conduction. The strength of the whisker is far higher than that of other chopped fibers, and the whisker can be used for manufacturing high-strength composite materials. In the prior art, no report is made on modification of geopolymers by whiskers.
