Geopolymer thermal insulation building block filler and preparation method thereof

Abstract

The invention discloses a geopolymer thermal insulation building block filler and a preparation method thereof. The environment-friendly masonry mortar provided by the invention comprises the following components in parts by weight: 700 to 950 parts of an industrial solid waste admixture, 0 to 250 parts of cement, 1 to 3 parts of a foaming agent, 1 to 3 parts of a stabilizer, 4 to 20 parts of a reinforcing agent, 50 to 80 parts of sodium carbonate, and 300 to 560 parts of mixing water. Compared with the prior art, the geopolymer thermal insulation building block filler has the following beneficial effects that: the foaming process is stable, the volume is controllable, bubbles respectively form independent closed spaces, and the transmission paths of heat and sound are prolonged, so that agood heat preservation and insulation effect is achieved, the added sodium carbonate excitant is weak base, so that the uncontrollability of alkali construction is prevented from being directly enhanced, and the setting time of the filler is shortened, the raw materials mainly come from industrial wastes and are easy to obtain and low in cost, so that the environment is protected, and the workingperformance of the thermal insulation building block filler is improved.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a geopolymer thermal insulation block filler and a preparation method thereof. Background technique [0002] In recent years, my country has vigorously advocated building energy conservation, making self-insulating blocks widely used. The fillers of existing thermal insulation blocks are usually materials such as foam, polyurethane, polyvinyl chloride plastic particles, polystyrene plastic foam. The above materials are not resistant to high temperature and easy to burn, which poses a huge threat to the fire resistance of buildings; other commonly used cement-based foam fillers have large capacity and high cost; aluminum powder and hydrogen peroxide foam fillers are uncontrollable in volume, Secondary processing and cutting are required, and the process is complicated. At the same time, its water retention is poor, and it is easy to lose water in the brick holes, resul...
