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...

The above, as well as some other benefits of the proposed system achieved through the establishment of more effective compared to other developers, methodologies and mechanisms in the estimates and frameworks, namely [1, 2]:
   1. systematic approach to determining the cost of construction, taking into account:
   - The type of investment and construction projects;
   - Member of the investment process, for which the following cost estimates;
   - The type of documentation that runs the cost estimates (pre-investment, design, bidding, contractual, construction or operational);
   - Regional features pricing;
   - Sources of construction financing.
   Formulated in relation to other factors and developed an innovative methodology and computer technology to determine prices for construction products that comply with international standards. In its development of generalized global best practical experience in the estimates construction of major investment and construction projects in Russia and abroad;
   2. system principles and information linking all cost engineering tasks, allowing you to determine specific requirements for each task and to develop more effective methods and estimated regulatory frameworks. For example, to budget calculations on pre-stage and early design stages have been presented specific requirements for their accuracy depending on the type of facility and its geographic location;
   3. universality of the proposed system for the application of different methods in the estimates, namely, resource, resource-ranzhirnogo, resource-and index-basis-index, depending on the actual situation and the capacity of members of the investment process. In addition, recommendations are their most effective use in the current, medium and long term to improve the accuracy and reasonableness of the estimated payments. For example, for a linearly extended objects (LPL) preferred method of resource estimate calculations, because range of resources to organize monitoring of their prices relatively low. Ploshchadochnyj for objects with significant nomenclature needed for construction resources, preference is given to the resource-ranzhirnomu methods allow to significantly reduce the range of resources to justify the resource database-representatives, providing sufficient accuracy of forecast budget calculations and other direct costs.
   Basis for budget calculations regardless of their staging must be physical indicators, namely: physical volume of work, labor, mashinoemkost, materials and equipment needs. In their absence, using the proposed (or develop additional) database objects analogues (which at 1 km of LPO or 1 m3 buildings are typical volume of works and other physical parameters), users of the information system, the database market prices for resources are able to obtain resource and traditional local cost estimates, providing the basis for the formation of object and summary estimate. When this information system provides the possibility of calculating overheads estimated profit and other costs as a regulatory and calculation methods.
