Abstract

The invention discloses a foamed geopolymer and a preparation method and application thereof. The foamed geopolymer is prepared from the following ingredients in parts by weight: 30-50 parts of metakaolin, 40-50 parts of an alkali-activator, 1-4 parts of coal ash, 2-5 parts of a foaming agent, 0.3-0.7 part of a foam stabilizer, 0.3-0.8 part of modified sisal fiber, 1-4 parts of paraffin emulsion,5-10 parts of water and 0.3-0.7 part of absolute ethyl alcohol. Compared with a traditional anti-permeability waterproof cement base material and a cement base protection material, the foamed geopolymer has the good material crack resistance, excellent waterproof performance and the outstanding endurance quality, good using performance can be maintained for a long time, and the foamed geopolymer has the properties of acid resistance, alkaline corrosion resistance, freeze thawing resistance and carbonization resistance, and can be widely applied to the field of basic engineering such as tunnelcomposite linings.

Description

technical field

[0001] The invention belongs to the technical field of geopolymer-based materials, and more specifically relates to a foam geopolymer and its preparation method and application. Background technique

[0002] Geopolymer is a kind of AlO 4 and SiO 4 Inorganic polymers composed of tetrahedral structural units in a three-dimensional network structure belong to non-metallic materials and are used in building materials, high-strength materials, solid nuclear solid waste materials, sealing materials, and high-temperature resistant materials.

[0003] Foam geopolymer is a new type of inorganic energy-saving and environmentally friendly material, which has the advantages of fire resistance, non-toxicity, heat preservation and heat insulation. With the vigorous development of the domestic construction industry, there is an urgent need to increase the service life of foam geopolymer products in order to reduce the construction and maintenance costs of the construction...
