The application of the fire-retardant heat-insulating coatings the application of light fillers is considered the effective method of fire protection of structures. Work is dedicated to the development of the new effective cement fire-retardant and high-temperature (oxidation-resistant) vermikulitobetonnykh composites with the use of ashes and pumice. It is revealed, that the application of construction gypsum and lime as the agent of the concealed hydraulic activity of pumice it made it possible to considerably reduce the expenditure of cement without reduction in the strength of fire-retardant composite. By wood by that saponified 0,1- 0,3% of the mass of cement the expenditure of water for the mixture is reduced during the introduction of resin, the density of vermikulitobetona decreases by 40-50 kg/m3. Is investigated the influence of the parameters of fiber reinforcement by basaltic fibers on the properties of vermikulitobetona. Are revealed the high fire-retardant properties of the developed fibrovermikulitobetonnykh composites. It is established that the addition of the volcanic pumice of the fraction d< of 0,16 ppm 30% of the mass of cement significantly increases the high-temperature (oxidation-resistant) properties of concrete block with a simultaneous increase in the bending strength and without noticeable reduction in the compressive strength. The replacement of the part of the volcanic pumice by the distended vermiculite makes it possible to reduce the average density of the vermikulitobetonnogo composite and to increase their high-temperature (oxidation-resistant) properties.

Increase of productivity of processes of sedimentation of coverings on the restored surfaces of details of cars without decline in quality of the received deposit is a main objective on the way of improvement of galvanic processes. Productivity of galvanic sedimentation depends on the size of potential of the cathode and the anode; from concentration of components of electrolyte about a surface of sedimentation (cathode); from uniformity of delivery and dispersal of ions of metal on a sedimentation surface; from quantity of active sites of the cathode; from nature of passivation of the cathode; from temperature of electrolyte and from the speed of the movement of electrolyte in prikatodny space. Very strongly passivating of a cathodic surface limits the possible growth of productivity of galvanic sedimentation. Passivating consists in education on a surface of the cathode of the continuous passive film consisting of hydrogen, products of reaction of metal with electrolyte components, oxygen of air and foreign inclusions. The passive film is almost insoluble and disturbs electrocrystallization process, shielding a cathodic surface. And cathode covering speed a passive film directly depends on density of cathodic current. It is possible to assume that at achievement of some value of density of cathodic current the speed of formation of a passive film will exceed, the speed of delivery of ions of metal to a cathodic surface and origin of crystals of the besieged metal will become impossible. And on the remained active sites of the cathode where the passive film is absent or has the smallest thickness and growth rate, there will be centers of growth of crystals of metal (dendrites) on which there will be a concentration of the main processes of electrocrystallization. That is the cathodic surface of the restored detail will become covered by the local centers of sedimentation of metal – dendrites. The passive film interferes with growth of limit density of cathodic current at which receiving qualitative electroplated coating is possible. Mechanical elimination of a passive film during sedimentation of a covering considerably facilitates process of electrocrystallization and formation of a layer of metal on the processed detail surface, provides increase of uniformity of the received layer of metal and its microhardness, and also will prevent active formation of local sites of growth of dendrites at the high density of current.

The analysis of the existing personnel management system of the territorial generating companies of the Rostov region, on the example of JSC LUKOIL-Rostovenergo is carried out. The main directions of a personnel management system are considered: opportunities for professional development and career advance; package of social payments and privileges; moral incentive. Procedure of carrying out a self-assessment of workers and a technique of definition of annual awarding of each worker of one of the territorial generating companies is considered: criteria of carrying out a self-assessment, sequence of carrying out and a formula for calculation of total point for calculation of indicators of awarding. In the conclusion expediency and efficiency of carrying out of this sort of actions of the employees of JSC LUKOIL-Rostovenergo directed on human resource management is analysed.
