Abstrakt: The issue of wastes reclaiming in large cities is really a pressing problem today. First of all, the wastes which occupy wide areas of land need to be reclaimed. The metal production slag and waste water sediments are typical examples of such waste products. They create a wide area of ecological and social discomfort when collected and accumulated in large quantities after treatment. The purpose of this study is development of new soil materials which include waste products. The material properties can be influenced in a level of electric-surface interaction of the studied system components. The phase boundary presence and high degree of dispersion of the components require considering the sign of the charge of the particle surface and the particle size, influence of the charge on the nature of interaction between the surfaces and thus allows defining possible methods of modifying the surface properties in order to obtain materials needed. This includes modification of the surface of the aggregates and filling agents, activation of the functional groups, dispersed system stability, coagulation control, etc.
