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...

In the absence of the possibility of the formation of local businesses in the estimates in the detailed work in the proposed nomenclature system provides a database (or the possibility of its extension to a particular user) aggregated physical and cost indicators at 1 km of LPO or 1 m3 (1 m2) building (structure), and calculation algorithms that provide sufficient accuracy in the estimates in the local aggregated nomenclature construction works and resources.
   Schematic diagram of the task information system linking the example of determining the value of oil and gas construction is presented on page 65. The main objectives of investors, customers and contractors capital construction are [1, 2]:
   1. improving the regulatory framework of the federal budget in 2000 with the development of new standards and amendments to the old, embracing new technologies and methods of construction, new materials, machinery and equipment;
   2. improving sectoral, regional and corporate estimated regulatory frameworks-specific regions, industries and enterprises;
   3. resource development and technological models of the physical volume of work per unit of capacity building production facilities by representatives from regional-bound. For example, 1 kilometer of the diameters of the various conduits or 1 m3 (1 m2) ploshchadochnyj objects;
   4. development of a system to monitor market prices for resources and marketing systems to choose the most effective resource providers;
   5. development of norms and standards for the estimated cost of temporary buildings and structures, overhead and other costs;
   6. development of software systems (PCs) and databases for the calculation of the cost of construction of various types of objects;
   7. calculations (examination) of the cost of construction of various types of objects based on the developed a PC within the pre-investment, design, tender, contract and other documentation;
   8. development listings current and forecast prices for the construction of various types of objects (for practical results in the estimates based on the PC resource and technological models representatives of objects);
   9. effective participation in the examination of estimates and negotiating contract prices;
   10. effective participation in the development and review of tender documentation.
   It should be noted that the establishment of the system should be implemented in phases and may occur sequentially or in parallel with the development of mechanisms for determining the cost of construction and overhaul of linearly extended and ploshchadochnyj objects. For example, at the facilities of "Gazprom" information system created for: the main and field of steel pipe; pipelines in urban and rural areas of steel and polyethylene pipes, power lines, roads, compressor and pump stations, commercial buildings, facilities housing and social nature. The most difficult task is to develop mechanisms forecast budget calculations on pre-stage and early design stages, providing no more than 10% deviation from the estimate made by the working drawings.
