Geopolymer building material and preparation method thereof

Abstract

The invention discloses a geopolymer building material, which is prepared from the following components in percentage by mass: 30 to 70 percent of geopolymer, 30 to 70 percent of lightweight aggregate, 10 to 15 percent of anticorrosive anti-oxidation pigment, 3 to 5 percent of compatilizer, 3 to 5 percent of processing aid, 1 to 3 percent of ultraviolet absorbent and 10 to 30 percent of water, wherein the geopolymer is powdery; the lightweight aggregate is granular. The geopolymer building material meets fireproofing performance requirements in the field of the energy conservation and the heat preservation of current buildings, accords with relevant application standards in indexes of volumetric weight, compression strength, a fireproofing class (class A1) and the like, and can completely meet the performance requirement of a fire barrier of an exterior wall of a building; not only can the current situation that materials in the field of energy conservation and fireproofing are deficient be effectively relieved and the steady promotion of the energy conservation work of the building be accelerated, but also the occurrence of a fire hazard of the building is also inhibited from a source; the actual use requirement is met.

Description

technical field [0001] The invention relates to a geopolymer building material 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 by 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 room temperature, the energy consumption ...
