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...

 Public  control  -  the  way  to  improve  safety  urban  development  activities  (2)

From 2001 to 2004 the amount of fines for administrative violations in the field of construction in the Russian Federation increased from 60 to 115 million rubles. While the number of protocols on administrative offenses increased from 13 to 34 million, a ruling on administrative offenses from 10 to 32 thousand.
   To a large extent it is connected with a sharp decline in industrial and technological discipline, responsibility and qualification artists at all stages of construction products, the level of engineering services and production control.
   Russia has no legal acts regulating the safety of the construction of buildings and structures.
   The same applies to their operation. The level of exploitation of responsible public and industrial buildings and structures does not hold water. No public service designed to give the state supervision over the operation of these facilities.
   All this is due to the fact that at the legislative level is not set peculiarities of state control and supervision in the establishment and subsequent operation of construction products. Not taken into account its specific properties:
   - Long-term construction and subsequent operation of the building structure;
   - The individuality of each building, ie possession inherent only in it constructive and internal technical parameters;
   - Constant interaction and exploited under construction object to the environment, resulting in a change in its properties;
   - The inclusion of real estate as an element in the complex in its structure education system - urban and rural settlements;
   - A large number of businesses, officials and citizens involved in the design, construction and operation of the facility.
   The role of state control in improving safety and preventing accidents construction of buildings and structures is extremely responsible.
   The new Town Planning Code of the Russian Federation is no definition of the State control urban development activities. State control is transformed into its form - supervision.
   Functions and powers of enforcement authorities is not sufficiently defined. This drastically reduces the effectiveness of their activities.
   At the legislative level, the rule of law did not adequately address the procedures for state supervision exercised in the operation of residential buildings by public housing inspection. This is all the more important to do in terms of the planned increase in housing construction and reform of housing and communal services.
   Analysis of the rules governing the institution of state control of urban development activity shows that compliance and enforcement in the conditions of market relations in this sphere, regulated enough.
   To be continued.
