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...

 "Kurortproekt"  -  spatial  design.  Part  2

Institute "Kurortproekt" designed spa facilities throughout the former Soviet Union, mainly in areas with complex geological conditions, high seismic and very often distant from the developed database construction industry.
   For projects "Kurortproekt" in the 80s built a number of spa facilities in the "cellular" structure:
   Sanatorium "Mikrobioproma" in Yalta. 80% holds bearing structures. In 1987, construction stopped.
   Sanatorium for 500 seats in Yalta is a "honeycomb" structure consisting of overlapping discs and orthogonal system of walls. Thanks to the work of all the spatial structures, building overhangs in the corners of almost 20 meters and has an atrium in the center of 40x40 meters, over which there are medical facilities and swimming pool.
   Housing sanatorium "Ukraine" in Yalta. 80% holds bearing structures. In 1992, construction stopped.
   Dormitory sanatorium "Ukraine" is a 3-storey building, in terms of sinusoidal with one-sided arrangement of rooms.
   Housing located on a hillside and has a tilt toward the mountains. Thanks to the constructive system "honeycomb monolith" housing managed without increasing sections of structural elements rely on widely spaced supports.
   Complex over the railway at the Paveletsky station. Conceptual design, executed in 1992
   Supports building of business center located at a distance of 50 m in the transverse direction and have a pitch of 18 m in the longitudinal direction. The span of 50 m width defined paths railway; 18 m step allows you to place two rows of cars in the garage and 4 living rooms by 4.5 m at the hotel. Construction of the business center is projected to account for the spatial operation of the building as a whole, the system of "cellular monolith."
   Multi-storey garage with a business center over the railroad on the Square. Gagarin. Feasibility study carried out in 1997.
   The complex is an 8-storey building three lower floors - garages, five upper floors - business center.
   Longitudinal walls span of 66 meters located 18.6 m step and have a height of four and seven floors. Thanks to the work of spatial structures on the principles of "cellular monolith" materials expenses slightly exceed the costs for the building, standing on a solid foundation.
   Hotel and business center (Fig. 2). Draft project developed in 1988. The building is a ball with a diameter of 85 m
   Outer "shell" of the ball - bearing concrete "cellular system", where are the hotel rooms and offices. This outer shell is based on three stairs and elevator towers, which in "shell" are also based social structure of the restaurants, cafes, auditoriums, gyms, casino, pool, etc.
   For buildings in the "cellular" constructive system opens up completely new possibilities.
   So virtually no increase in the consumption of materials:
   You can build public buildings over highways, railways, on slopes, ie develop land that is inappropriate for traditional construction. Such construction will develop the vast territories of cities engaged highways, reduce environmental damage from transportation, tie areas of the city, highways fragmented, and solve the problem of construction of garages, shops, offices, sports halls and other public buildings in areas of the city with the most dense residential development;
   You can build a residential neighborhood of houses torn from the ground and stair-lift blocks, placing the entire territory of the district under the park, children`s playgrounds. With skillful design district will turn into the park, with its hanging over the vegetation, residential buildings.
