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...

1. Composition
   Building technologies to ensure public safety, areas and construction sites with hazardous natural and man-made impacts include the following main areas:
   formation of stable to natural and man-made situations of natural and man-made systems (NTS);
   protection of buildings and structures from the disastrous effects of earthquakes, permafrost degradation, subsidence grounds groundwater flooding and other natural and techno-natural processes;
   Technology and Engineering reconstruction of destroyed villages, buildings and structures;
   fire safety Shatter buildings and structures;
   radiation safety of building materials, structures, buildings and structures;
   Establishment of zoning maps in Russia by natural and anthropogenic factors of construction and monitoring of hazardous natural processes;
   Developing management of natural and man-made risks engineering construction solutions as a factor in reducing the vulnerability of emergency.
   2. Purpose, basic functional parameters
   Integrated security solution to create natural and artificial habitats under adverse impacts of natural and man-made building technologies has a high socio-economic and ecological importance in the framework of the concept of sustainable development of the Russian Federation.
   High efficiency stable emergency (natural and man-made, including) building systems of various functional purposes determined by the host architectural-planning, design and survey, design, technology solutions based on the achievements of the complex building sciences, engineering and technology, and information systems .
   3. Sphere of application
   The proposed technologies are usable for the formation of a secure environment, an effective response to emergency situations of different origin, risk reduction and mitigation under the influence of natural and man-made disasters, which are subject to the development of regions, occupying more than 70% of the territory of the Russian Federation. The proposed technologies apply to architectural planning, design, survey, design and engineering, materials science and construction activities for all types of building systems.
   4. Basis for Selection
   Meaning of emerging technologies to the following factors:
   creation of high resistant to impact factors of natural and manmade disasters building systems at all levels and responsibilities, including earthquake engineering, protection from flooding, landslides and hydrodynamic phenomena of climatic events, floods, development of underground space, building on undermined areas and explosion-proof fireproof construction, with the exception of radiation, chemical and bacterial contamination;
   the formation of efficient technologies, techniques and methods of rescue, repair and remediation work in the natural and man-made systems in emergency situations;
   establish systems for forecasting, prevention, early warning, mitigation as elements of a risk management system based on modern information technology;
   empowerment of safe construction development opportunities for adverse development of natural hazards and technological accidents and disasters.
   5. Status and trends of development
   Currently, the share of construction in regions prone to natural and man-made "emergency" is more than 50% of the total construction and tends to increase. Expanding development of territories with degrading permafrost, are involved in the construction sector seismically active areas being built on undermined areas, up to 80% of urban areas flooded Russia, etc. Up to 70% of labor costs and time spent relates to construction aspects of harm reduction and elimination effects of increasing the number of natural and man-made emergencies, and taking into account mitigation measures, this value increases.
   Proposed technology corresponds to the direction of federal programs "Housing", "My house", "Security."
