Discusses actual problems of determination of the resistance and protection of concrete structures – slabs, produced by standart adopted in the Russian Federation and the United States. Studied national and international experience of evaluation and quality control, measures to preserve the integrity and stability of structures to various types of exposure. The focus is on those conclusions that must be made from the analysis of the causes of destruction in order to avoid future repetition of mistakes and miscalculations that are allowed currently in the design and construction of engineering structures and which often lead to the occurrence of accidents.

Keywords: methods of quality control, concrete structures, failures of engineering structures

The aim of this work is to study the degree of protection of underground waters of the Kuibyshev district of Rostov region. The study area represented by the geological deposits of Quaternary (recent sediments) Qh, Neogene and Paleogene systems (Oligocene) P3, Cretaceous (upper division) K2 and the Carboniferous system (upper, middle and lower portions) S1,2,3 based. On the analysis of geological structure of water-bearing rocks in the Kuibyshev district of the Rostov region, which showed an insufficient degree of protection of underground waters against pollution and, as a consequence, insufficient supply of public drinking water, built map of underground waters protection of the Kuibyshev district of the Rostov region

The analysis of existing methods of water use when applied galvanic coatings in the automobile transport sector. It is established that under the existing schemes of water use in the galvanic production wastewater after cleaning goes into the sewer, keeping the risk of contamination of open reservoirs. In such circumstances, the most effective is the use of system of the closed water cycle, which with the help of automatic control allows to take into account changes in the concentration of substances laundered in the washing baths providing the required quality of washing parts with a minimum consumption of water resources.

The article presents the results of the sociological survey analysis of the technical institute students. A systematic analysis of the socialization peculiarities, connected with the problem of spiritual security in modern society, is carried out. The issues of spiritual security are relevant, since it is the spiritual attitudes that govern the practical activities of each person in individual self-realization.
