A brief account is first given on the significance of using slag lignin as a chemi- cal grout material from the viewpoint of utilizing industrial waste, enlarging the source of grout material, decreasing cost and limiting environmental pollution. Main results of laboratory experiments are given in the article, including pro- perties and formulation of slag lignin, factors affecting setting time and strength of congelation, the permeability and viscosity as well as toxicity of slag lignin. All this provides the experimental basis of the application of slag lignin in engineering practice. Practical examples of waterproof sealing of inclined shaft stations, signal cham- bers and power substation chambers are described in the last part of the article. 95% waterproof efficiency is achieved and in some cases of exploration drilling even 100% sealing is attained. In conclusion, the author highlights the advantages and prospects of the use of slag lignin in the field of waterproof sealing. The author also points out the direc- tion for further research on slag lignin.
