Conductive mortar, high-conductivity conductive cement-based material and preparation method of conductive mortar and high-conductivity conductive cement-based material
The invention relates to conductive mortar, a high-conductivity conductive cement-based material and a preparation method thereof, and the conductive mortar is prepared from the following raw materials in percentage by mass: 36-41% of cement, 1-3% of a curing agent, 1-3% of a curing agent, 1-3% of a curing agent, 1-3% of a curing agent and the balance of water. 19-20% of water; 0.5-1% of a water reducing agent; 0.5-3% of graphite; 0.1 to 0.5 percent of carbon fiber; 7-8% of silica fume; 30-32% of machine-made sand; 0.1%-0.2% of a carbon fiber dispersing agent and 0.01%-0.08% of a defoaming agent; wherein the particle size of the graphite is 800-1200 meshes. According to the invention, the graphite powder with low doping amount and small particle size is co-doped with the carbon fiber with low doping amount, and the silica fume is used cooperatively, so that the graphite powder can be uniformly dispersed in a mortar system, and the conductive performance of the conductive mortar can be remarkably improved by matching with the carbon fiber uniformly dispersed in the system, and meanwhile, the filling effect of the graphite powder with small particle size is utilized to improve the conductivity of the conductive mortar. The high-strength cement-based material is obtained.
