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.

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...

JSC Khabarovsk plant "Fiberglass" - the largest producer of heat insulation of building materials in the Russian Far East and Siberia. With the introduction in 2001 of new requirements for thermal insulation of building structures, plant for three years conducted a reconstruction of the existing line for the production of wired mats in order to establish a new production building insulation material - semi-rigid boards with a wide range of density and thickness (50 to 175 mm) . Previously, this type of construction materials in the Far East district had been made, thanks to which products have become competitive and not inferior to Russian counterparts, as well as foreign companies. Since last year, the plant started production of sandwich panels of various colors.
   In turn, OAO "Tomsk housing company" - one of the largest manufacturers of precast concrete in the Tomsk region, also produces aerated concrete blocks. Aerated concrete - is a lightweight, warm building material made from it blocks convenient for transportation and building lodges and cottages. To perform work on the landscaping company constructed houses and other consumers mastered the production of various grades of paving slabs that takes into account one of the main conditions - safe operation in winter conditions. The company is the only Russian producer of foam glass - high-performance insulation, production of which is mastered and brought to design capacity in the year before.
   It should be noted that, to date, the issues of forming a market for affordable housing development and improvement of industrial building construction, including construction prefabrication homes prefabricated and monolithic buildings in many regions and cities decided on the basis of the design and implementation of advanced techniques of various companies and organizations . One of the leading in the industry is the Federal State Unitary Enterprise "Design Office for architectural and building systems and new technologies of the AA Yakushev "(FSUE" KB them. Yakushev AA ").
  
   Leaders and outsiders
   In the first quarter of this year in the capital, built about 1 million 120 thousand square meters. meters of housing, it is 3.7% less than in the same period last year. The plans of the Moscow builders - to build this year to 4.5 million square meters. meters. But talk about the construction boom will be possible only in the case where the volume of housing construction in Russia will be increased by 4 times.
   But in general, I say where the authorities dealing with the issue of housing, there`s a payoff. Where pay little attention ... We have, unfortunately, bad things in housing construction in the Ulyanovsk and Saratov, Smolensk and Murmansk regions, Altai Krai and Ingushetia. I have already spoken about the Far East: Magadan, Kamchatka - things are not going well there. This is to some degree related to the objective problems - delivery of construction materials, fuel and energy resources, with severe climatic conditions. But a lot of subjective
