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...

 Cellular  polycarbonate  helps  architects  to  solve  many  problems  CITY

Popularity rating cellular polycarbonate on the Russian market of building materials today is very high and tends to further growth. Appearing with us only a few years ago , it still causes more joyful surprise ordinary townspeople (clear, light scattering , light, heat insulation , durable and incredibly beautiful! ) . They " open it for themselves," and understandably seek and find for this material to good use (mostly it is realized in cottage construction - gallery, sheds, greenhouses , conservatories , as well as in interior design - ceilings , walls, elements design ) . For Professionals same urban scale - architects , designers, builders - this plastic is "open" , and today he is " leaps and bounds " extending from the central Russian cities in depth and breadth , in realizing magnificent architectural projects , bringing in the urban landscape of lightness and airiness , giving his contemporary sound . Are born and realized all exciting new projects , using the maximum advantages of this plastic.
Sharply in recent years embarked problem saving helps to attract even more attention to the cellular polycarbonate as the material has a very high insulating properties.
Purely from an aesthetic point of view, cellular polycarbonate contributes to urban architecture and ease of " lightness " and big cities saturation brick and concrete structures " unloads " the urban landscape , making it more modern and attractive . Prospects cellular polycarbonate apparent in urban construction and application possibilities are far from exhausted .

Application of cellular polycarbonate construction in various urban facilities
Overlapping markets and shopping complexes . In connection with the Moscow Government on the need to streamline the market trade, construction of new shopping centers and reconstruction of existing markets popularity cellular polycarbonate " has reached a new revolution ." Cellular polycarbonate quickly and can solve the problem of reliable transparent covering these structures . Large centralized markets in Moscow already have similar coverage (eg Cherkizovsky market ) . Typically, this type of construction of the arch . It is not only beautiful, but also cost-effective solution , and quite simple in execution. In the majority of under construction and planned markets , given the positive experience of projects already implemented , also used a coating of cellular polycarbonate .
Overlap of sports facilities ( From tennis courts and ending stadiums, such as Moscow's "Luzhniki" ) . In our climatic conditions covering sports facilities of cellular polycarbonate keep them running throughout the year with maximum comfort for visitors. They are durable and reliable, beautiful and enhance the prestige of the sports facilities.
Lights of buildings, the transparent roof sheds, vertical glazing industrial buildings . Overseas use cellular polycarbonate for such purposes is very developed . Large size panels , their impact resistance, high thermal and acoustic insulation , lightness of the material and the ability to use the simplified frame construction , substantial cost savings on lighting and heating - it is undeniable facts in favor of cellular polycarbonate .
