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.

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...

 Technology  economical  and  technological  security  waste

1. Composition
   Technology economically and technologically safe recycling include the following main areas:
   reconstruction and construction of landfills and sites for storage and domestic and industrial waste;
   recycling, reuse and recycling of products processing and recycling;
   restoration and rehabilitation of technologically contaminated territories, including vibrozasorenie, radioactive and chemical pollution.
   2. Purpose, basic functional parameters
   Development of control systems handling waste production and consumption, including the construction of the landfill sites and their placement, storage and processing, construction and development of remediation of contaminated areas technologically cities and settlements is one of the priorities and challenges of industrial society. The solution to this problem requires the development of complex geotechnical and foundations of ecological, climatic estimates based on regional conditions associated with geo-ecological environment and the nature of man-made pollution.
   Their development and implementation will greatly streamline the design, survey, design and technological development, significantly reduce labor, material and energy rehabilitation of technologically contaminated areas, including in the management of waste management will create the conditions for improving the quality of life and environmental safety cities and other settlements.
   Efficacy:
   Environmental - improvement of the environment and ecological conditions in the form of reduced emissions of all kinds of pollution, including those associated with waste disposal;
   Economical - use waste products production capacity expansion of the existing landfill, including the implementation of the possibilities for accommodation on it industrial waste, saving areas potentially allocated under landfills, reduced costs for waste disposal, return into circulation of contaminated areas, including mastered in an urban environment.
   3. Sphere of application
   The proposed technology can be used in all the urban areas of the Russian Federation, regardless of their population, but with the local geographic, climatic, geological, urban and resource conditions.
   4. Basis for Selection
   The problem of waste management of consumption and production in conditions of increasing the amount of waste they need, recycling, reuse, storage and disposal, as well as the need for rehabilitation and remediation of contaminated areas with technologically urban construction, the return of these areas in an environmentally safe and cost-effective use is permitted by creating a system of geotechnical and environmental foundations of economic assessments construction development of technologically polluted cities and territories control treatment of waste production and consumption, including the construction of the landfill storage and processing.
   This system is ideologically compatible with existing, carried out by the GIS technology, corresponds with the proposed information system and geo-ecological environment of the city may be one of its subsystems.
  
   5. Status and trends of development
   One of the most important elements in the management of waste treatment is the construction of landfills and software remediation of landfills, remediation of contaminated areas technologically.
   Poor enforcement of technical literature, including the lack of federal and regional building codes and regulations governing the design and construction of landfills, remediation work and technologically sanitize contaminated areas, technical specifications for building materials used at these sites, largely determines provokes the deterioration of existing environmental situation.
   For reference, each year in the Moscow region produces about 8.5 million tons of waste and comes to accommodation from Moscow about 4 million tons of waste.
   The bulk of domestic and industrial waste is recycled and not placed in landfills, authorized and unauthorized dumps, the territories of enterprises that poses a serious danger to public health, an irrevocable loss of secondary resources.
   In the present period in the Moscow region recorded 210 authorized landfills and dumps, identified about 100 large illegal dumps. Number of illegal dumps succinct incalculable.
   Proposed technology corresponds with the federal program "Waste".
