USE OF BY-PRODUCTS IN FOUNDATION ENGINEERING

The paper deals with methods of stabilization and improvement of steel-smelting waste products, that is, open-hearth slag, and of wastes obtained from sulphur ore treatment processes, that is, water-saturated carbonate sludge. Some examples of utilization of fresh and dump slags in foundation practice are presented. A method is given for desiccation of carbonate sludges by treatment with a non-uniform direct electric field which greatly improves their physicomechanical characteristics. (TRRL)
