Abstract

The invention discloses a novel geological polymer and a preparation method thereof. The novel geological polymer is prepared from the following components by mass percent: 10-45 pelelith micropowder, 18-50 dolomite micropowder, 5-28 superfine slag powder of iron tailings and 2-20 an alkali-activator. The geological polymer provided by the invention has properties of early strength and rapid hardening, is good in volume stability, chemically corrosion-resistant, high in interface bonding force, good in anti-permeability, good in high temperature resistance, hydrothermal action-resistant and good in durability, is capable of automatically adjusting temperature and humidity, and the like; the pelelith micropowder in the novel geological polymer is light in mass and high in strength, has heat insulation property, sound absorption property, fire resistance, acid and alkali resistance and corrosion resistance, is free from pollution and radioactivity, and the like, thus being an ideal, natural, environment-friendly and energy-saving raw material; the dolomite powder in the novel geological polymer is beneficial to the improvement of early and late stages compressive strengths of the geological polymer; if the powder is finer and the mixing amount is more, an early enhancement effect is more remarkable.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a novel geological polymer and a preparation method. Background technique [0002] With the improvement of people's awareness of environmental protection and energy conservation and the regulations of national policies, various industries have increased their research and development efforts in environmental protection and energy conservation to better protect the environment in which human beings live. [0003] Geopolymer is one of the non-metallic materials that has been studied very actively in the world in recent years. It is a new type of inorganic polymer material obtained by chemical reaction at a lower temperature with silicon-containing solid materials such as clay, industrial waste or slag as the main raw material. It can replace cement for construction, Roads, artificial islands, prefabricated components, refractory materials and other fields. ...
