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...

 Future  development  in  safe  hands  (3)

At the plenary session of the conference "Creativity young XXI Century: Realities and Perspectives" with presentations by the head of VVC MH Musayev, chairman of the Education and Science of the Russian State Duma NI Bulaev Rector MGSU VI Telichenko Academician SP Kapitsa, etc.
   The next two days were held breakout sessions, which were undergraduate and graduate students. Four of the five sections organized MGSU concerned building subjects: "Mathematical and software research in construction", "Problems of Ecology and Environmental Biotechnology", "Architecture and Urbanism" and "Construction materials and building technologies." Interesting reports were made by students and graduates MGSU RUDN, MIKHiS, MSUEE, MGVMI, MIIT MGUP, PGUSA.
   Section on "Architecture and Construction" was presented 56 projects, including 11 projects submitted by graduate students of the Moscow State University of Civil Engineering.
   Most interesting, in our opinion, were the following projects: "Accounting for spatial planning and urban factors in complex reconstruction of a five-story residential buildings 50 - 60s", made postgraduate IV Dunichkinym, AY Egorov and OV Tyumeneva under the guidance of the doctor tehn. Sciences Professor V. Alekseeva, "Monorail transport system OCE", made a postgraduate EN Yevseyev led by TV Frolova, "Problems of production and non-autoclaved cellular concrete solutions", the author - a student of KV Kyianytsia, director - Dr. Sci. Sciences Professor BN Rodionov, "Complex" Sport Russia "VVC" made ER Hakobyan led by PhD. tehn. Associate Professor AA Agasyantsa; "Using fine-grained concrete in load-bearing structures", made a postgraduate NA Medvedeva led by PhD. tehn. Associate Professor AP Pustovgar; "Smolensk NPP-II turn, the completion of construction. Complex processing of radioactive waste (KPRAO) ", made research student MV ŽIAKOVÁ led by PhD. tehn. Sciences Professor BK Pergamenschikova.
   According to the results of a thorough study of each project, interviews with authors projects Scientific Committee consisting of 6 persons determined the winners.
   First place in the section "Architecture and Construction" won graduate student MGSU
   IV Dunichkin. Winner of the "Looking to the future VVC" declared EN Evseev, also a graduate student MGRS. Valuable gift (cell phone) awarded student MGSU KV Kyianytsia for practical significance of the project.
   All 16 authors of 11 projects submitted by graduate students MGSU and 2 teachers were awarded diplomas STCY party.
   Moscow State University of Civil Engineering was awarded individual diploma "For a lot of work in the development and support of scientific and technical creativity of youth."
   Congratulations to the winners!
   To be continued.
