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...

 Astana  -  breaking  the  XXI  century.  Part  1

Overall architectural composition of the city, the idea of ​​the development of Astana was formed over ten years ago. The basis of the architectural concept of building lay thought of President Nursultan Nazarbayev of the Republic, that by virtue of its geographical position, Astana is to become one of the centers of Eurasia, but because in her appearance should organically combine Asian and European features.
   Astana today - this is the most European of all Asian capitals. Architectural idea here is refracted in the light of philosophical ideas. As is known, the general plan of the new capital designed by renowned Japanese architect Kisho Kurakava. Calm and organically - the main style signs new capital. Philosophy of symbiosis and metabolism as the basis of the master plan, based on the principles of sustainability and innovation, a combination of modern design and oriental color create a unique city creation, creativity and progress.
   From the date of transfer of the capital carried out work to create the most beautiful city in the world. Every year in Astana appeared and appear unique structures capable of its architecture decorate any metropolis of the world, and almost every one of the objects symbolic capital.
   To date, in the territory of the left bank of the capital of the Directorate of Free Economic Zone (SEZ) "Astana" - new city "154 registered object. During the work on the left bank of Astana FEZ object 73 already in operation. Under construction are 10 office buildings, 23 community facilities, 24 residential buildings. In addition, another six major facilities are in the planning stage.
   Hallmark of the city became the Independence Monument "Astana-Baiterek". Handmade wood, lit by a golden glow glass bowl, symbolizes the desire for goodness, light and joy. The monument is a building height of 97 meters, a figure that coincides with the year of birth of the capital.
   In 2005 began the construction of the beautiful majestic building - Palace of Peace and Consent, authored by world-renowned architect Norman Foster. Building height of 62 meters and a total area of ​​25.5 thousand square meters will be provided in the form of an Egyptian pyramid. The upper part of the building - glass, metal construction of the Palace includes seven floors.
