" The analysis of the influence of superplasticizers based on polycarboxylates on the formation of physical and mechanical properties of concrete under thermal influence. It is established that the high efficiency of the steamed self-compacting concrete with polycarboxylate-based superplasticizers is achieved at low-temperature modes of heat treatment. Rational mode of heat treatment of concrete should be assigned to the quality parameter established by the results of experimental studies. Article is published within implementation of the program of the International Forum «Victorious May, 1945»."

Some approaches to assessment of soundness of investments necessary for implementation of results of research engineering are described. It is proposed to use the method of variation of parameters with the establishment of some restrictions. The results of the application of the proposed methodology are given on the example of evaluating the soundness of investments in the technology of unburnt synthanite from natural raw materials in the apparatus with vortex layer and the production of wall stones based on it. It is rational to use the proposed methodology in the formation of an investment plan, the development of business plans, and the implementation of graduate qualification work. Article is published within implementation of the program of the International Forum «Victorious May, 1945».
