The peculiarities of polymer mortar application for renovation and restoration are determined on the basis of priority data integration about the destruction mode of valuable historical buildings. The possibilities of controlling technological, physical-mechanical, and operational properties of recovery polymer mortar due to the aggregates of different nature are shown.
For the analysis and optimisation, the quantitative relations between the structure and property factors of recovery polymer mortars and the factors of recipes and technology determining them were obtained in the form of experimental and statistical models calculated using the COMPEX system. The optimisation methods of recipe and technological solutions based on the use of experimental and statistical models are proposed.
The optimisation of polymer mortar composition according to the package of quality indexes and property stability at high temperature has been carried out. The package of "mixture-technology-properties" models has been obtained, with the help of which the change mechanisms of direct and summarizing indexes of mixture technological properties and mechanical properties of recovery polymer mortars have been established when changing the type of aggregates (ceramics, quartz, carbonates, their binary and triple mixtures).
The influence of aggregates on the durability change of polymer mortar under the influence of various temperature-climatic and operational factors (UV-irradiation, alternate action of temperature and aggressive aqueous solutions) has been studied.
It is recommended to use quantity and type optimal aggregates to provide the complex of technological and operational properties of polymer mortar and to reduce the consumption of imported polymer. The rational compositions of polymer mortar with increased stability of properties under changing temperature and climatic conditions are proposed for different restoration technologies.
The series of nomograms have been developed for the initial selection of the "area" of rational polymer mortar compositions, providing for further correction in relation to a specific repairable object. Technological and marketing analysis according to the research results are carried out.
