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."

As difficult as builders now, many firms successfully overcome the crisis zone. Necessary to reduce administrative and estimated costs, intensify marketing activities, more demanding select suppliers and partners. It is difficult and customers. Their mission - to properly use those little tools that can be allocated for the construction and repair. Each customer has to decide for themselves the question whom to entrust the construction, repair or reconstruction of the enterprise, office, apartment. Anyone looking in their own way through the old ties, on the advice of friends or colleagues, advertising. Sometimes we have to choose a contractor almost blindly, guided interior and the size of its office or advertising that often overly optimistic.

   Who else can safely entrust their resources? So that they were used technically correctly and sparingly to have ordered to guaranteed quality at a reasonable price. Best of all this question would answer itself building a community where everyone knows each other and jealously watching the success (or failure) colleagues.

   In Moscow, the constituent assembly of the Independent Guild building contractors (NGSP).

   The initiators of creation became the founders of a number of construction and engineering companies, building materials industry enterprises of Russia and Belarus: JSC "Ergostroy" Company "Respect", LLC "Stroyzem" Group companies DSM, Inc. CEC "Compound", Moscow branch nationwide fund "Center of the quality of construction" and others, as well as a number of private entrepreneurs.

   Guild was created to provide on-

   power contractors, customers and manufacturers of building materials. Therefore, the main tasks of her three: to provide contractors with orders, maintain and disseminate the best achievements in the field of construction and provide one another with building materials and machinery manufacturers and their customers.

   To ensure the volume of construction and design work orders for construction materials Guild intends to actively promote the products and services produced by its members. Provide them with access to the latest technical and market information. Organize contracting trades needed to find partners contacts. Provide assistance to its members high-class specialists: engineers, architects, marketers, lawyers and others whose services regularly or from time to time require any construction firm. After hiring them on a permanent basis or to pay for outsourcing many simply can not afford. Say, to put its own representation on the Internet, must be invested thousands of dollars, and if united, can save great.

   To make life easier for customers, the Guild will take care for the selection of contractors, architects, designers (including foreign), project coordination, construction, delivery and registration of the object, picking furniture and equipment. She will pick up customers such firms and professionals who timely and properly fulfilled all works, give guarantees on buildings and equipment and thus ensure the safety of investments.

   Assistance to producers of building materials, machinery and equipment aimed at organizing guaranteed sales. One way to accomplish this is to use first products manufactured by guild members. But the Guild is not going to be limited to the promotion of these products only in the circle. She will be able to develop and execute a competent marketing program for any of the manufacturers aggressively and widely present its consumers in the target audience segment at exactly the time chosen.

   Guild is a nonprofit association of voluntary and protecting the interests of both employers and contractors building and construction industry and enterprises, directly or indirectly related to these activities in various areas: financial, credit, advertising, marketing, scientific, technical, educational , publishing, legal and many others.
