Abstract

Main objective of the presented work is the research influence of additives of technogenic products of chemical water treatment of combined heat and power plant on physical-and-mechanical properties of paving slabs. Modern trends in technological development envisage the processing of technogenic products of the energy complex using them in the production of building and finishing materials, which is an important reserve of resource saving in construction. The X-ray phase analysis of technogenic products of chemical water treatment is presented. As a result of the research conducted, the possibility of using such waste for the production of general purpose building materials based on concrete mixtures has been established. For the manufacture of experimental batches, the dosages of the components were calculated taking into account the addition of chemical water treatment sludge. At JSC «Obolsky Ceramic Plant» a pilot experimental batch of paving slabs was made for further research of physical, chemical and physical-mechanical parameters. Studies have shown that adding from 7 to 10 % of waste improves the molding properties of cement mortar in the production of paving slabs.
