Novel building material adopting geopolymer and preparation method of novel building material

Abstract

The invention discloses a novel building material adopting a geopolymer and a preparation method of the novel building materials. The novel building material is prepared from, by weight, 30%-70% of the geopolymer, 30%-70% of lightweight aggregates, 10%-15% of anti-corrosion anti-oxidation pigment and 10%-30% of water, wherein, the geopolymer is power-like, and the lightweight aggregates are particle-like. By the arrangement, fireproof performance requirements in the current building energy conservation area are met, indicators of volume weight, compressive strength, fireproof grade (grade A1)and the like all comply with relevant application standards, performance requirements of fire protection zones for exterior walls can be completely met, the present situation of material shortage in the field of energy conservation and fire protection can be effectively alleviated, steady progress of energy conservation work in building is promoted, building fires are restrained form the source, and actual use requirements are met.

Description

technical field [0001] The invention relates to a novel building material of geopolymer and a preparation method thereof, belonging to the technical field of building materials. Background technique [0002] Geopolymers are amorphous to semicrystalline three-dimensional aluminosilicate materials, and mineral raw materials with pozzolanic activity and industrial solid wastes can be used to prepare geopolymers. The mineral composition of geopolymer materials is completely different from Portland cement. It is composed of amorphous minerals. Its main raw materials are highly active metakaolin, fly ash, slag, etc. Sodium, water glass, potassium silicate, etc.), a class of inorganic non-metallic materials that can replace Portland cement formed after batching, mixing, adding water and stirring, and forming through hydration polymerization and dehydration hardening within a certain period of time. Because the preparation of geopolymer is completed at normal temperature, the energ...
