Description
Technical Field
The invention relates to the technical field of functional building materials, in particular to a fly ash-metakaolin-based conductive geopolymer and a preparation method thereof.
Background
In recent years, functional building materials include not only coating materials, sealing materials, and porous insulating materials applied to the field of building materials, but also cathodic protection materials gradually applied to energy-oriented materials such as conductive materials, electromagnetic field interference, electrostatic discharge, and reinforced concrete structures. However, most of the current researches on functional building materials are focused on cement-based conductive concrete prepared by replacing part of the aggregate with a conductive medium.
The existing common conductive phase materials are mainly graphite, steel fibers, carbon black and chopped carbon fibers. When the conductive building material is prepared and graphite is used as a conductive phase, the sample has good conductivity only when a sufficient amount of graphite is added into a matrix, so that the compressive strength of the sample is greatly reduced, and the practicability is reduced; when the steel fiber is used as a conductive phase, although the mechanical strength of the sample can be increased, the resistivity of the sample is unstable for a long time, and the problems that the steel fiber is easy to agglomerate due to large doping amount and the conductive grid is difficult to form due to small doping amount of the steel fiber exist; the particle size of the carbon black and the presence of reactive groups on the surface of the carbon black affect the conductivity of the sample. In contrast, the chopped carbon fiber is doped as a conductive phase, so that not only can the toughness of a sample be enhanced and the compressive strength of the sample be improved, but also a good conductive network structure can be formed when the doping amount of the chopped carbon fiber is small.
Compared with cement-based conductive concrete, the geopolymer has great advantages in the aspects of technological performance, mechanical performance, flame retardant performance and environmental protection performance, has wide application prospect, and is one of the best materials for replacing silicate cement in the future. Therefore, the invention provides a fly ash-metakaolin-based conductive geopolymer and a preparation method thereof.
