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...

 Construction  skyscrapers  -  the  requirements  of  modernity.  Part  1

In the last decade we have seen a rapid increase in the growth rate of globalization localities. Tendency to raise living standards, requirements for comfort residence leads to the concentration of population in large cities. And Moscow is a glaring example. Only in the last five years, the population of Moscow increased by 2 million people (8.54 million in 2001 to 10.425 million in 2006)
   This naturally leads to the growth of the city and increase the volume of construction, both residential buildings in the first place and the necessary urban infrastructure of schools, hospitals, shopping and entertainment centers, the organization of parks and playgrounds.
   Such volumes of housing construction in Moscow generate lack of available land for development, as their price increases with each passing day. To date, remained inde-point structure of the unit within the Moscow Ring Road and bare fields beyond, where to build liquid housing at Moscow prices possible. At the same time the level of land prices we have overtaken almost all cities of the world.
   According to the mayor of Moscow, the limit "sprawl" city breadth is currently exhausted. On the other hand, the growth process uncontrollable metropolis, it will increase faster and faster. Where? Where to find reserves for mass building?
   Construction of tall buildings in big cities - a global trend. Along this route passed many megacities not only the U.S. but also in Western Europe.
   But not only the shortage of land makes the city grow up. Construction of skyscrapers and is a matter of prestige. Currently, some cities in the world is impossible to imagine without abutting against the sky high buildings. This is primarily American cities - Chicago, New York, Los Angeles and, of course, and the capital city of Australia and Asia - Tokyo, Hong Kong, Shanghai, Singapore, Kuala Lumpur, Sydney and others.
   It should be understood that the implementation of the construction of high-rise complexes require the latest technology, experience, highly qualified specialists. All of this suggests a certain level of economic development. It is for these factors, the foreign investor`s country`s investment potential, market maturity.
   To be continued.
