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...


 Information for builders




  Firm "ASI engineering" (MSL License Mosstroylitsenzii number 037011), one of the divisions of the corporation "Nechernozemagropromstroy", since 1995 the first in Russia to start working actively to implement the construction of the outer insulation of buildings.

   After careful study of foreign experience in this matter (the system were studied exterior insulation in Greece, Italy, Sweden, Finland, Belgium, Czech Republic, Slovakia, Slovenia and Germany) the most appropriate and versatile for Russian construction conditions, we chose one of the German technology developed and used since 1964 by "Hacken DEMMSISTEME GmbH", is the leader in this field in Germany and Western Europe.

   In 1996, the technology "Hacken-TISS" (insulating related system), and in the future "RUSKHEKK" was received technical approval for the Construction Committee of Russia number 1.

   Currently, the system is fully adapted to the Russian market of construction (obtained technical certificate signed Gosstandard, hygienic certificate and other permits, including the conclusion of the finish layer NIIMostroya facades), and some components (adhesives, reinforcing compounds) produced by domestic enterprises.

   For three years (1996 to 1998). Exterior insulation work on "RUSKHEKK" performed at 22 sites in Russia, including 12 sites in Moscow and Moscow region (UES office building on the street. Chelomey 5; office building "Alfa-Bank", a complex of buildings of the Bolshoi Theater, the first spiritual gymnasium Tessinsky lane. 3; houses Kashirskoye str. Tolbukhina in Maryino, Zhulebino, residential village "Godunovo"; homes in Domodedovo and Nazareva) . Total heat-insulated over 120 square meters residential and office buildings.

   Performing engineering services firm "ASI engineering", with its highly qualified and have passed an annual internship in Germany, has trained more than 170 workers and line managers of construction companies in Russia, including in Moscow - the company "Orbit", " Mosstroy-16 "," Promstroy "(JSC" Mospromstroy "), the company" Zarubezhrestavratsiya "," Tempstroy "," room ", NGO" Stroytehnologii "Senior dry mixtures plant, the company" ADD "," SWEET "and others.

   More than 80 top managers of construction companies, engineering and architectural institutions, administrations of cities and regions of Russia are familiar with the technology "RUSKHEKK" with a trip to Germany.

   During practical work firm "ASI engineering" constantly improved systems employed. So a number of sites (First Spiritual gymnasium and school Krasnoselskoye Lane in Moscow, children`s cafe in Yaroslavl, a house in Cheboksary) work carried out year-round, separating them into two stages. 1st step - installing insulation and reinforcement in the winter, 2nd stage - finishing layers (primer, plastering and painting) in the warm season (spring, summer).

   Using complete system "RUSKHEKK" We are working with various heaters - Minplita density of 140-160 kg / cu.m firms "Paroc", "Rocwool", "IZOMAT", as well as polystyrene plates as a German, and domestic production.

   Three objects we performed on the mixed variant, when the main façade is insulated foam slabs and concrete slabs framing openings and crosscuts (fire zones) mineral wool.

   This option gives you a significant depreciation of the cost of 1 sq. insulate the surface, because a total price of 40-50% is the cost of insulation.

   Unfortunately, our experience and that of others has shown that the domestic min-

   plate production plant in the Railway can not be used (in the form in which it is produced today) in the outer insulation of buildings.
