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 źFederal 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...

 Specialized  exhibition  źArchitecture.  CONSTRUCTION╗

At the opening ceremony with a welcoming speech to the participants spoke: NG Vasilyev, head of the urban complex of the Ministry of Construction, Architecture and Housing and Communal Services of the Republic of Tatarstan, Rustam Mukhametshin, head of the construction of the same department.
   The exhibition featured more than 50 participants from different regions of the Russian Federation, including local businesses and organizations. Great interest among the specialists called the following products.
   Facade systems OLIS
   System of ventilated facades with air gap "OLIS" is designed to improve telozaschity peripheral shells of residential and public buildings, made of different materials and is recommended as a finishing facade coating under moderately cold climate with a lifetime of at least 30 years. The distinctive characteristics of the facade systems are:
   Ľ the variety of decorative facade sheets ("OLIS-Stone" - the surface of natural stone chips of different colors and fractions, "OLIS-Color" - one-colored sheets, "OLIS-Billing" - with textured polymer coating and mineral filler);
   Ľ quality facade insulation (insulation thickness from 50 to 200 mm) and high noise insulation;
   Ľ ensuring delivery deadlines materials.
   Brick penodiatomitovyy teploizoljatsionnyj
   Diatomite plant produces heat insulating foam diatomite brick. Diatomite - light finely diatomite breed algae.
   The company produces brick in the following sizes: 248h124h64 mm 230h114h64 mm 230h114h76 mm 220h110h60 mm 250h250h65 mm. A distinctive feature of the products are excellent heat transfer properties, high mechanical strength, low thermal shrinkage, light weight and high porosity, and high fire resistance and sound insulation properties.
   This brick is used in ferrous and nonferrous metallurgy, energy, glass, cement, petrochemical industry. It is designed for thermal insulation of buildings, industrial equipment (electrolysis cells, smelting furnaces, boilers, pipelines, etc.) at a temperature of insulated surface to 950 ░ C.
