Conductive carbon black composite cement mortar and preparation method thereof

The invention provides conductive carbon black composite cement mortar and a preparation method thereof, and belongs to the technical field of cement mortar buildings. The conductive carbon black composite cement mortar provided by the invention is prepared from the following preparation raw materials in parts by mass: 380 to 420 parts of ordinary Portland cement, 1300 to 1500 parts of medium sand, 270 to 310 parts of water and 1 to 12 parts of conductive carbon black Super-P. By adding the conductive carbon black Super-P in a proper proportion, the cement mortar is good in conductivity, the conductivity of the cement mortar is greatly improved, and the adopted conductive carbon black Super-P is simple to prepare, very low in production cost, very high in economic practicability, simple and economical in overall preparation process and suitable for large-scale use. Results of the embodiment show that compared with common cement mortar, the conductive performance of the conductive carbon black composite cement
