Cement-based conductive composite material based on conductive aggregate and preparation method thereof
The invention provides a conductive aggregate-based cement-based conductive composite material and a preparation method thereof, and relates to the technical field of cement materials.The conductive aggregate-based cement-based conductive composite material is prepared from 650-750 parts of cement, 10-20 parts of carbon fibers, 300-400 parts of conductive aggregate, 5-8 parts of a water reducing agent, 2.5-4 parts of a dispersing agent and 0.5-1.5 parts of a defoaming agent, and the conductive aggregate comprises clay and a mixed conductive phase; the mixed conductive phase comprises carbon fiber powder, carbon nanotubes and carbon black. By doping the carbon fiber powder, the carbon nanotubes and the carbon black in a reasonable proportion and reasonably distributing the proportion of the cement, the carbon fibers and the conductive aggregate, the conductive effects of the carbon fiber powder, the carbon nanotubes, the carbon black and the carbon fibers can be effectively exerted; finally, the cement-based conductive composite material based on the conductive aggregate has good conductivity and can be better applied to grounding construction of an electric power system.
