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...

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...

 Radio  and  Television  Tower  in  Vilnius.  Part  1

Vilnius radio and television tower - easy to view high-rise building - rushed into the sky like an arrow in a residential area of ​​the city buildings, on the right bank of the Neris River. Authors of the project paid special attention to the development of high-rise architecture and designs with rigging Review lookout located at around 165 + m above the ground. There is a bar-restaurant called "Milky Way" and other technical facilities. Visitors and tourists to the top of lift speed passenger elevators. Their distinctive feature is the placement of the engine rooms downstairs in the basement floors dimensions. At the same time lift facilities has three independent power supply, including the emergency diesel generator. He comes into operation in case of emergency and in the event of an emergency evacuation of visitors from the upper floors.
   For maintenance and utilities output visitors from the upper floors inside dimensions of reinforced concrete television tower trunk mounted spare ladder.
   During the tour, visitors will details of architectural composition television tower, its design features and construction methods. Downstairs visitors show a detailed layout of the TV tower, the location of the main floors and equipment of radio stations from the upper observation deck, guests can admire the magnificent panorama of the city, ancient castles and new buildings adjacent residential areas with bird`s-eye view.
   The observation deck at the Vilnius TV tower has a rotating ring floor. Sightseers, standing in one place, make a tour of the town with a single point, and then rise to the restaurant floor.
   Broadcast the first television broadcasts in Lithuania began in 1957 May Day holidays in those years in Vilnius television center was built the first model with a metal pillar antenna height of 180 m, which aired only one black and white program. And only a quarter century later, in the capital have decided to build a new multi-program television center with the TV tower on an individual project height 326 m, gear 4 television programs and 4 radio channels on VHF FM. This significantly increases the radius of coverage area programs, their quality and the ability to transition to color television broadcasting.
