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...

 Consortium  of  engineering  and  technical  audit  of  the  security,  reliability,  efficiency

In recent years, Russia has become increasingly important issues of reliability and safety of new construction. This is primarily concerned with program development areas with complex geological conditions (especially when building the slopes with a developed network of gullies and ravines), industrial construction and unique structures and social sport. Large-scale new construction projects require the use of advanced integrated technologies for reliability, safety and efficiency of these objects at all stages of their life cycle.
   The need for consolidation of the professional experience of leading experts and specialists in the field of technical, environmental and energy audits, comprehensive application of advanced methods and means of nondestructive testing state residual life of reliability and energy facilities, demanded organization "Consortium engineering audit" (ITA).
  
   That consolidation of the capacity of members of the consortium, based on the results of surveys of more than 1500 buildings, utilities and systems, allows you to:
   - Exclude system errors related to the underestimation of complex natural environment in the design and construction;
   - To simplify the process of releasing the IRD for each object individually;
   - To carry out computer simulation to predict complex geological processes in the entire area of ​​construction and development of an effective system of protection engineering facilities located in the building area;
   - To carry out expert diagnostic support of the processes of construction, acceptance and operation of buildings, utilities and systems;
   - Develop and create duplicated secure having a predetermined safety margin, system engineering development area networks;
   - To reduce the cost of repairs and renewals of buildings and equipment through the use of technology engineering and technical expertise, diagnostic scoping;
   - Improve the reliability and safety of operating buildings, structures, systems and equipment, as well as the quality of contract works through the use of non-destructive testing, engineering and technical audit and situational dynamics simulation;
   - To reduce the cost of heating buildings by optimizing the thermal protection and control systems, heat consumption and heat;
   - To develop a system of automatic control of the state of engineering structures and communications and general monitoring of buildings and structures;
   - To reduce construction time and ensure their quality;
   - To diagnose the quality of construction of modern, highly informative and reliable NDT methods;
   - To reduce the payback period of the objects by minimizing the volume of emergency repair works during construction and in the first 3-4 years of operation.
