05 The invention relates to mortar compositions used predominantly in masonry and the installation of paajraHHbix building structures. The famous construction solution is the 1st solution, which includes fluffy carbide lime, eoluunos, electrostatic dust and water ij. The disadvantages of this mixture were npoHi iocTb and frost resistance as well as increased shrinkage. The closest in terms of teosnicheskoy, core and achieved results to the proposed mixture of fine-grained mixture, including Portland cement, ash, sand, gypsum, water and lime 2. The disadvantages of the known mixture are strength, low frost resistance and increased shrinkage. The purpose of the invention is to increase the strength, frost resistance and reduce the shrinkage of the solution. The goal is achieved by the fact that mortar, including Portland cement, sand, dry ash or hydropower TP removal and water, additionally contains crushed fractionated fuel slag stone screenings, or burnt coal rock of a fraction not more than 5 mm at the following component ratio, May . %: Portland Cement 13-ZO Pesok15-45,6 Crushed fractional fuel slag or KaMeHHHjt screenings, or burned mine fraction no more than 5 mm18-35 Fly ash OR ash padroudalen TPES6.5-9.4 Water. Introduction to the mortar composition of crushed fractionated fuel slag or stone sifting, or burnt shadtnyh rock allows you to adjust the grain composition of natural sand and to obtain optimal aggregate granulometry, which increases the strength, frost-resistant bone and reduces the shrinkage of the solution. The mortar contains dry: / 10 ash or ash of hydrolayering of thermal power plants in the optimum: There is mobility and water retention capacity of the solution, Zola not only plasticizes the solution, but also plays the role of an active mineral additive :. At the same time, it applies simultaneously to the particles of cement and sand, helping to create the optimal structure of the solution, which additionally increases its strength and frost resistance. The proposed mortar makes it possible to use local fine sands without cement overspending. In addition, the area of application is extended (by the mineral industry waste in construction 6. Example. To obtain a solution in a mortar mixer, equal-moving mixtures of the proposed and known compositions are prepared. 51057461b
