Modification of plaster compositions for building facade finishing with nanotechnological materials

Analysis of the modern state of the facade system market was conducted, major deficiencies and basic requirements to facade surfaces and materials were identified. It was established that high quality of the surfaces is achieved through stability of the composition and properties of the raw materials used, and fillers – their quantitative content and dispersity – play a particularly important role. The problem of the optimal filling of plaster compositions, labor intensity and low profitability of natural filler production was raised A solution was suggested: expand the nomenclature of fillers for plaster compositions of the new generation, apply nanotechnological raw materials, in particular, carbonate sludge – the product of reactant treatment of waste water from thermal power plants and carbonate siliceous product – flue dust from asphalt concrete plants. Both wastes are depositable anthropogenic sources of environmental pollution. Formulations of facade compositions, modified with nanotechnological mineral fillers with high properties (adhesive strength, compressive strength, cold resistance), confirmed by a number of Russian patents, have been developed
