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  3

Radio and television tower in Vilnius is designed by specialists of the State union Design Institute (SSDI) of the Ministry of Communications of the USSR, having rich experience in designing similar structures. At the time, repeatedly noted that after the construction of the Ostankino TV tower height of 540 m in Moscow, this tower in Vilnius, built from the usual not-stressed concrete, was the third TV tower height (after the Ostankino and Berlin) and can serve as an example of the use of design solutions in the construction of similar facilities in many cities.
   TV tower in its lower section rests on concrete foundation formed by the annular base plate thickness of 1.5 m with an outer diameter of 38 m Stove monolithically connected with two conical shells. Given the engineering-geological structure of soils mark laying foundation base is taken to be - 8.25 m to accelerate work on the construction of foundations and reduce the cost of installing formwork structures, cone-shaped part used spatial reinforcement cages prefabrication.
   From the outset, the construction of a reinforced concrete slab foundation, construction tools were organized regular monitoring of their deposits. As a result of many years of observation precision leveling methods found that over a six year period, a minimum draft of one edge of the foundation was 9.5 mm, and the draft of the opposite equaled just 12.3 mm. Thus, for high tower buildings average foundation settlement amounted to 10.5 mm, which is within the allowable values ​​for these towers.
   Above the base around the TV tower built of reinforced concrete two-storey barrel rigging, which carries the input and lift lobbies, technical and auxiliary facilities. The total usable floor space on the lower floors of the rigging of 3391 m. meters. On the construction of the lower rigging together with the foundation spent 944 cc. meters of concrete, 88 tons of reinforcing steel and 164 tons of rolled metal. The total cost of this part of the constructions TV tower is 25% (fourth) of the total cost of construction.
   Entry of visitors, the technical staff of the TV tower is made through an underpass, recessed into the ground at -3.6 m
