| Summary |
"The paper industry, in its process of manufacturing pulp from wood, produces large quantities of a substance called lignin, lignin sulphite, or lignosulphonate. This material has been disposed of as a waste product; however, it does have many potential uses. In this investigation, lignosulfonates were used as agents for bonding rock sections together and, as the chief component of gels, for filling the pores of artificial rock cores. The purposes of these tests were to find how this substance could be used in the mining industry, for stabilizing fractured ground around mine openings and for sealing off water influx into mine openings. Strength tests conducted on cemented sections of rock and permeability tests conducted on the sealed cores indicated that lignosulfonates would make effective stabilizing and sealing compounds, when used under the proper physical conditions and when the correct proportions of chemicals were employed. a major advantage of this substance over other cementing or sealing agents is its los cost, which in most cases would be far less than any other known substances used for these purposes"--Abstract, leaf ii. |
