Protect the surface of the concrete floor
To protect the concrete floor, which is operated in the normal mode, or is subject to wear in areas with high traffic, there are several ways to protect the surface.
   Comparable ways: their cost, appearance and ability to perform the task to protect.
   In this article, we consider three ways to finish and protect the floor. Each of them has its advantages and disadvantages.
   Thin fil...

Finishing compositions based on water glass. Part 3
When used as part of exhaustion moderator comes coagulation and solidification of liquid glass. However, due to the presence in the composition of Portland cement with a finishing time is an increase strength of the coating due to hydration of cement minerals. Thus from colloids formed during the coagulation liquid glass are actively assigned to the water for hydration of cement, a porous media formed tumors filled Portland cement, which leads to...

Geophysical processes primers and security. Part 5
In the center of Moscow can distinguish vertical structure comprising a crashing into the Earth`s crust magma elongated cylinder (Fig. 2) [5]. In the center section marked lack of extensive vertical zone converted waves ("blind spot"), going from the depths of 70-80 km to 7.5 km. Such "blind spots" are characteristic of the earth`s crust with the introduction of monolithic dense mantle rocks such as gabbro, diabase, etc. In such a zone Tashkent e...

Finishing compositions based on water glass. Part 1
The quality of the decoration of buildings for new construction and reconstruction depend not only on their aesthetic, but also the operational parameters, as good-quality finish - a guarantee of durable service basic designs, long maintenance-free operation, the costs for maintenance and care. Traditional binders used for the production of finishing compositions, liquid glass is widely used, but it has some drawback: coatings based on it gaining...

On possible amendments to the equation Griffiths
Griffith presented a picture of destruction allowed to formulate the problem of determining conditions of the beginning of crack propagation and find its general solution.
   As seen from the above schemes, in the process of crack propagation material directly adjacent to it "coasts" unloaded relaxes. This means that the stress and strain it decreases, and the elastic energy stored earlier in this area of ​​the body is re...

 Revitalization  of  public  science  and  technology  policy  in  the  construction  and  housing  sector.  information  system  geoecological,  geotechnical  and  geological  environment  of  the  city

1. Composition
   Information System geoenvironmental, geotechnical and geological environment of the city - IP HPP - is the basis of Investment building complex.
   IP HPP city integrates information obtained as a result of exploration, scientific research and monitoring, as well as existing and currently developed specialized databases geodesic, geographical, geological (including geomorphological, hydrogeological, etc.) hydrological and related character. IP HPP city involves information stored in turnover documentary funds of different departments and organizations fragmented, unsystematic data accumulated over the previous years of research, which are mostly federal property. IP Hydro is part of the information management system investment building complex city. IP HPP city includes the following subsystems with the necessary range of graphic, electronic, textual materials, software, databases:
   I. Geological Information
   II. Geotechnics, geomechanical information
   III. Environmental Information
   IV. Information about the future development of the city
   2. Purpose, basic functional parameters
   Create an information system geoenvironmental, geotechnical, geological environment of the city (on the basis of the developments made for Moscow) is an effective modern, highly intelligent framework as the basis of Investment building complex in emerging cities (with population growth, population density and the need for reconstruction of the existing urban ) with global trends of the ecological crisis.
   Basic principles, ideology, software IP HPS are easily prevalence of other urban ecosystems at various levels and the state of our country, and are consistent with similar systems being developed abroad, primarily on the principles of reliability and environmental safety.
   3. Sphere of application
   Information System geoenvironmental, geotechnical, geological environment of the city is creating an information base for reducing the complexity, volume and timing optimization of design and survey works and inspection of existing urban development, high-performance building technologies justification for resource and energy saving principles and a new generation of environmentally friendly building materials , optimizing the design of engineering solutions ensuring high reliability and environmental safety of the urban environment.
   IP-based GES non-departmental information centers, which are in direct management administration (Government, City Hall) cities, are an effective tool for developing new and historic cities in all geographic and climatic and geological conditions and under any condition of the facilities and the level of development of investment-building complex .
   4. Basis for Selection
   Recent geo-environmental problems associated with the construction of development in the context of increasing urban population, accelerating urbanization, expansion of the geographical space occupied cities, the spread of cities in an increasingly diverse geological and climatic conditions, including the particularly complex and extremely complicated conditions at new construction and reconstruction of buildings, structures (all levels of responsibility), a complex of buildings, utilities (including and underground construction) within the existing dense urban demand for multidimensional security for long-term and operational decisions of administrative and managerial, investment, architectural and planning, design, survey, construction, technological and operational matters associated with the use of the geological environment in the active development pressure on the urban ecosystem, creating an information system environment of the city as the basis for the management of its investment-building complex.
   5. Status and trends of development
   Collect information on the status and parameters of geo-ecological, geotechnical, geological environment of the city, located in the collections of various departments in the unstructured condition, as well as newly obtained information on the principles of ideology IP HPP city will ensure the effective use of geo-ecological information for different types of users, but mainly to manage complex investment and construction within city administrations decisions taken for the effective management and development perspective.
   Currently there is already a significant number of developments of this trend, carried out by the GIS technology that can effortlessly get into the city ready IP hydropower units or serve as the basis of its software and database storage.
   Creating IP HPP city as a critical technology component is highly intellectual and matched the best world achievements of information technology, as well as the possibility of obtaining results "breakthroughs" that significantly reduce the complexity, reduce the time of design and survey works, their optimization ensuring high reliability and environmental safety urban environment.
