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...

   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...

 Information  technology  for  determining  the  cost  of  construction  products  (2)

Experience innovation in OAO "Gazprom" indicates that the program of measures and actions to ensure effective information system pricing any investment and construction company should include [1, 2]:
   - Organizational activities related to the preparation of members of staff activities, the formation of a coherent organizational structure of users and system developers. The first step is the establishment of the parent company specialized organization responsible for the organization and methodology for the development and implementation of quality training materials justifying pricing construction projects, including the formation of contract prices;
   - Developing a methodology estimates made in the interests of the parent company and its subsidiaries, which substantiates system technology linking all tasks, including estimates and other information;
   - Development of methods and software systems for all types of facilities and all the stages in the estimates;
   - The development of the integrated element and the estimated norms and standards;
   - Conducting practical budget calculations on real objects;
   - Generalization of practical experience in the estimates with the creation and approval of listings physical and cost performance per unit of power generated by building products to various types ploshchadochnyj and linearly extended objects.
   Below focus on the benefits of the proposed methodology and information technology cost management in construction, each of which is further developed based on innovative mechanisms in the estimates and frameworks.
   The main features and advantages of the proposed methodology for determining the cost of construction projects are [1, 2]:
   - The possibility of determining the cost of construction at any stage of the estimates, namely: pre-investment, design, construction and operation, as well as the valuation of real estate with a view to sale, liquidation or reinvestment based on efficient algorithms and multidimensional estimates regulatory framework as enlarged per unit of power generated construction products, and element on the detailed types of work;
   - High precision in the estimates under full or partial absence of working documentation for the project (as part of the pre-investment documentation, feasibility studies of investment, project, tender and other documents), not exceeding 10% of deviations from estimates compiled by the working drawings on the basis of efficient algorithms and estimated regulatory frameworks, including objects peers;
   - The ability to calculate the cost of construction for each stage of the investment process in the current prices on the basis of the resource calculation methods and an effective monitoring system resource prices-representatives;
   - The ability to calculate the cost of construction in the forecast prices based mechanisms prognostic assessment of all types of resources and costs;
   - The ability to determine the predictive value of the construction of all types of investment and construction projects at the expense of established mechanisms in the estimates and the estimated standard databases per unit of power linearly extended (1 km of motorway) and ploshchadochnyj (1 m3 and 1 m2 building) facilities;
   - The possibility of determining the cost of construction of facilities for different climatic conditions due to the presence of the integrated element and the estimated regulatory frameworks that take into account the special conditions of construction and linearly extended ploshchadochnyj objects in a particular region;
   - The ability to more effectively study the contractual prices for building construction products, performance contracting and supply of resources;
   - The possibility of a more objective formation of state and territorial element estimate standards (GESN and TESN) and rates (FER and FER) on the basis of a more effective system of technical and tariff regulation, monitoring of current resource prices, as well as effective methods of accounting organization of construction (in-line construction methods , methods of network planning and management, etc.). This allows a more reasonable physical form standards (labor, mashinoemkost, material requirements), as well as the cost parameters for the execution of works and services.
