The paper presents the results of blast furnace slag treatment by low-temperature non-equilibrium plasma method. The blast furnace slag treatment process is carried out at the Moscow State University of Civil Engineering laboratory. An alternating current generator with voltages up to 8000 V and frequencies up to 40 kHz between the electrodes creates a low-temperature unbalanced plasma region. Research results show that, after blast furnace slag is treated by low-temperature non-equilibrium plasma method, cracks appear on the blast furnace slag surface. This leads to a decrease in grain size and an increase in the blast furnace slag Blaine fineness. In addition, the research results also show that the compressive and flexural strengths of the mortar sample using plasma-treated blast furnace slag are 71.08 MPa and 10.42 MPa, respectivel. That is higher than the mortar sample using the blast furnace slag untreated plasma, respectively 0.05 MPa and 8.70 MPa.
