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  1

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. These circumstances require creating a team with high skills, based on new and original design solutions for close contact with leading research forces in the country.
   In the sanatorium building regularly arises the need to create structures, technologically demanding large spans without support spaces: drinking galleries, concert halls (Kurhaus), pools of water with a large mirror, etc.
   "Kurortproekt" during its existence has designed a number of buildings with long-span spatial structures, such as:
   Angular cable-stayed shell diameter of 60 meters, built over drinking gallery in Yessentuki;
   monolithic hanging conical hull bottom outboard basin (Fig. 1), implemented in the pension "Friendship" in Yalta in the area with 8-point seismicity (patent number 775280).
   The experience gained in the design of spatial coatings resorts helpful for critical facilities in Moscow:
   dome of the Cathedral of Christ the Savior in Moscow, with a central dome, consisting of two-dimensional systems: outdoor tent in the form of radial space and the inner ring system 2 - layer sphere in the form of reinforced concrete domes with rigid reinforcement. Installation stiff reinforcement implemented 4-ring sections with mounting stress in the form of radial prestressed systems top and bottom mounting blocks;
   Floor atrium Old Dvor in Moscow as a system of prestressed arches arched tightening (patent number 2,121,042).
   At the time when the bulk of the design organizations was forced to rely solely on the precast concrete, "Kurortproekt" formed the concept for the monolithic reinforced concrete not only as to the material that best satisfies the claims of architects, but also adapted to solve the problems of building the steep mountain slopes, complex by ordinary standards, unfit for construction areas, but with recreational value.
   Thus, the idea to design a system much more complex level than the spatial coverage - house or space that now with the light hand of the author has been called "honeycomb monolith."
   "Cell" spatial constructions are building systems consisting of floor and wall drives combined into a single structure, working together.
   Buildings such as hotels, housing, business centers, sports complexes, etc., made in the "honeycomb monolith" could be based on widely spaced supports.
   For projects "Kurortproekt" in the 80s built a number of spa facilities in the "cellular" structure:
   The resort complex "Druzhba" in Yalta (author certificate number 806844) is operated from May 1985. "Friendship" is a single volume containing sleeping rooms for 400 people, a restaurant, pool seawater atrium with concert hall, bar, fitness and game rooms. The whole complex is located on a steep coastal slope, based on three monolithic supports, which are located in the elevators, stairs and utilities.
