  • UDC 69.003:658.011.8:728.1
    Alevtina M. KRYGINA
    Abstract. The basic directions of reproduction processes in construction are reviewed. It is shown that the reproduction, considered as a continuous process of renewal of fixed assets and prevent their premature wear, in construction includes three basic stages: preparation of construction, construction (construction industry), the implementation of the final construction products (input of buildings and structures in operation). For the implementation of a competitive strategy of development of the construction company should have a certain innovation potential, which gives him the opportunity to beat the competition, having received advantages in comparison with them, and achieve better results than they. The main goal is not to maximize the volume of the finished building products or minimizing the cost of consumed resources, technical efficiency or profit maximization but optimal co-couple of all organizational and technical and managerial aspects, which should be aimed at long-term planning of construction and its innovative development. Developed model of a competitive territorial reproductive system in construction and functional model of program-target interactions on the development of competitiveness through the implementation of innovative engineering solutions for the upgrade of the existing building.
    Key words: reproduction, competitive strategy, competitive territorial reproductive system in construction, innovative technological solutions, building.

    Elena S. GOGINA, Igor A. GULSHIN
    Abstract. Due to the tightening of standards for wastewater discharge which has been occurred during last 20 years, the problem of removal of nutrients (nitrogen and phosphorus) gained prominence. There was a need to develop methods and technological schemes of wastewater treatment to the required standards, promising to implement the renovations at existing treatment facilities and requiring minimal capital investment. The authors have reviewed and analyzed the application of one of these technologies, developed at the Moscow State University of Civil Engineering (MGSU). This technology is based on the work of the single-sludge denitri-nitrification system. It has been repeatedly shown its effectiveness while being used at wastewater treatment plants in the Russian Federation. Moreover this system has a number of advantages compared to other domestic and foreign technologies. The analysis of operation of the treatment plant in the city of Kolomna after reconstruction (with using the developed technology) proves the theoretical assumptions about the system. The results confirm the stability of technological schemes and give reason to recommend it for the further implementation when reconstructing wastewater treatment facilities.
    Key words: wastewater, ecology, treatment plants reconstruction, deep biological wastewater treatment.

    Abstract. Results of the study on the use of hollow glass and aluminum-silicate micro-spheres as a filler for lightweight concrete and rheological characteristics of developed mixes are presented. It is established that reducing the total area of dry components surface reduces the flowability of concrete mixes due to introducing micro-spheres into fine concrete composition. Reasons for increasing the water demand of mixes on the basis of hollow micro-spheres and the strength of offered concrete with the increase of volume content of lightweight filler are substantiated. Advantages of hollow glass and ceramic micro-spheres and also prerequisites for their use in production of high-strength lightweight concretes are indicated.
