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...

 About  the  rapid  pace  of  development  of  the  construction  industry  in  China.  (4)

Along with the great achievements in construction in China and there are certain difficulties, including safety during the works. Marked by numerous irregularities in safety on construction sites, which leads to a lot of accidents and emergencies, especially in areas prone to floods, rain and gale-force winds. Thus, according to the State Administration of work safety in China was recorded in 1324 fatalities in construction. Of the 40 million people employed in construction, almost 80% do not have any special training. The Ministry of Construction jointly by the General Inspectorate for their safety circular dated August 12 this year demanded from the regional divisions significant improvement in the production of construction works, including when working with tower cranes, earthworks, working at heights, etc. Circular prescribes exercise proper supervision and control of the execution of works projects where safety measures should be an important part. Local inspections should check the construction site to identify explicit and implicit threats to construction personnel and demand their immediate removal. In case of failure indications safety inspectors leaders buildings will be subject to the most severe penalties. Regional departments of construction indicated in strict compliance with the licensing of construction companies and record keeping of accidents and crashes.
   We have the theft and corruption in the construction industry. The country`s authorities are tough fight this evil, using the most stringent sanctions on those responsible. For example, building official accused of embezzling 2.8 million yuan ($ 345 million) intended to compensate resettled from the flooded area of ​​the dam "Three Gorges", was sentenced to death with reprieve in 2 years. The authorities claim that the number of such crimes in recent years has significantly decreased.
   Chinese builders pay considerable attention to the study and application at the best international practices, as evidenced by the large number of international conferences and exhibitions held in the country, as well as the participation of Chinese experts in similar events held abroad. Summit will be held in Beijing "International Construction", organized by the famous American publishing technical books McGraw-Hill Construction and China International Association of Building Contractors (CHINCA). Summit provide support as the Ministry of Construction and the Ministry of Economy of China, the municipality of Beijing and many large Chinese construction companies.
   The program of the summit:
   1. Financing of innovative projects in the international construction markets.
   2. Construction and planning of new construction in the conditions prevailing ancient infrastructure.
   3. Reduction of accidents and safety construction.
   4. How to position the company logo and its products to increase sales and market penetration of the Chinese construction.
   5. Impact on the quality of design quality and success of the construction.
   6. Investment risk management in global projects.
   7. New attractive areas for investment in the Chinese construction.
   8. Sustainable and biopozitivnoe (environmentally friendly) building in China.
   9. How to succeed in a global multi-national projects.
   10. What you need to know the leaders of global multinational projects.
   China`s achievements in the field of construction assure the appropriateness of domestic companies to enhance cooperation with Chinese partners to accelerate solutions to problems of domestic housing, including program to build affordable housing.
