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...

Finishing compositions based on water glass. Part 2
Studies in Berlin Institute Federal institute for Materials Research and Testing, show that the average density of 1730 kg/m3 brick large proportion of pores having a size in excess of 1 micron is more than 90% [3] and they are responsible for the increased migration of fluids through brickwork.
   Most fully meet these requirements structure obtained by coagulation and water-soluble potassium silicate forming silica with a high sp...

Modernization and repair of self-propelled machines. (3)
Hardening electrolysis BORATING hinge pins and bushings mates working equipment hydraulic excavators EO-4121 (EA-4321) gives an increase in wear resistance 4-6 times compared to the bulk quenching details.
   Taking into account the high wear resistance of brazed blades, hardened sintered alloys (see Table 1), are recommended for carbide knives dumps graders DZ-122 and RS-98, combined machine E-405 based on KAMAZ, for front dumps a t...

Mari-lime brick and gas silicate blocks
   JSC "MZSK" produces silicate brick and a half, color (white, yellow, black, red, blue, green, brown).
   For the production of silica brick used quartz sand from quarries near the plant. Limestone enters the factory with Dobryatinskogo deposit Vladimir region. Silicate brick (Table 1) is used for masonry exterior and interior walls of buildings and structures, as well as ...

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...

Construction skyscrapers - the requirements of modernity. Part 4
The program is a high-rise building in Moscow
   The project is now a high-rise building in Moscow is implemented in two main areas: the construction of business center "Moscow City" and implementation of the program of the Government of Moscow "New Ring of Russia."
   1. Moscow international business center "Moscow - City"
   The project includes the construction of buildings on the territory of abou...

Degree project - beginning of the road. (3)
Given the great diversity of subject matter and content of diplomas in various specialties, the jury is faced with great difficulties in determining the winners - "Who better violinist or a dancer?". Nevertheless, often based on emotional perception and can estimate the relevance and novelty, and the author`s contribution to the thesis project or job. Absolute winners in recent years have been graduates of Rostov CSO GASU St. Petersburg, Nizhny N...

 About  the  rapid  pace  of  development  of  the  construction  industry  in  China.  (2)

Together with the Ministry of Science and Technology developed and published guidelines for designing biopozitivnyh environmentally friendly buildings. In accordance with these rules, the design of buildings is estimated by the point system consisting of 6 parts: saving energy and natural resources, protecting the environment, the quality of the internal environment, the use of recycled materials, handling and use of buildings of national traditions in construction and architecture.
   The efforts of the Ministry of Water Resources to improve the quality of drinking water in China. Currently, more than 300 million people in rural areas do not have access to clean drinking water. In the period between 2001 and 2005. China has invested about $ 2.4 billion to provide drinking water to 60 million people, and by 2020 is supposed to provide quality drinking water to the entire rural population of the country.
   China plans to invest
   $ 24 billion to build 18 nuclear reactors of 1000 MW each, including 6 reactors in three eastern provinces (Fudziyan, Shandong and Liaoning). Currently, the production of electricity from nuclear power plants is 2.3% of the total electricity generated in China, and by 2030 it will be increased to 4.0%. In the past year in the Chinese province of Jiangsu, in Tianvan using Russian specialists have successfully completed the construction of the first nuclear power plant unit, will soon begin its industrial use. Cooperation in this area is supposed to extend to Russia, with special interest in the field to build floating nuclear power plants. Using the experience of the development of Russian floating nuclear power plant in Severodvinsk, a joint working group plans to carry out a project using Chinese export credits and the use of Chinese floating platform. Huge demand for energy in China has caused intense interest and the use of non-traditional renewable energy sources, including wind energy. It was recently announced the start of construction in Hebei Province wind power station with a capacity of 1,000 MW with concrete supports for the turbine height of 70 m
   China continues construction of ambitious construction projects, such as a race track for Formula 1 cars in Shanghai (about what we dream), a giant dam "Three Gorges" of tall buildings in Beijing, Hong Kong and Shanghai, with the involvement of famous American architects Skidmore, Owings and Merrill (SOM) of Chicago, the company joined the SOM design objects and lesser-known provincial cities, including in Nanjing. Near the international airport of Beijing started the construction of the exhibition center within an area of ​​153 hectares. The cost of the center is estimated at $ 241 million, the area covered premises is 370 thousand m2, construction completion scheduled for the end of next year.
