Abstract
The waste amount decreasing is an actual problem for the modern society. The waste products are accumulated around big cities or enterprises and create a zone of the economic and social discomfort. One of the ways of this problem solution is the waste usage as raw materials for construction. In this article the posible usage of slags and activated sludge of biological treatment plant of town sewage for the ground stabilization is considered. The samples consist of clay, metallurgical slags and activated sludge. They are studied by the electron microscopy method to define the changes of sample microstructures with activated sludge and without it. The research showed the difference between microstructures. It is shown that the samples with activated sludge are characterized as more dense and strong structure. It is explained that an organic component of activated sludge is an anionic surfatant which is adsorbed on the particle surfaces of slag and clay. Moreover, an inorganic component of activated sludge is represented by oxides which can activate the slags. Mainly, the hydratation products of slag were observed on the electron microscopic photos of these samples. The conclusion is made that activated sludge could be an alkaline activator for slags.
