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...

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...

 Consistency  in  scientific  and  technological  development  -  decisive  factor  for  economic  growth  building  complex

The most important goal of economic development is to ensure continuous growth of quality of life, and it, in turn, depends entirely on the technological independence of our country, to ensure the competitiveness of domestic products and support local developers and manufacturers.
   Complex prospective development of Moscow with his scientific and engineering potential has and will contribute to achieving this goal.
   It should be noted that today`s industry building complex has a small reserve for technological enough to respond quickly to market demand and social needs of the city. Development of innovations requires not less than 20% spare capacity for constant updating of products. In other words, the reconstruction and modernization of the construction industry - an urgent task, because companies are not able to engage in self-renewal and to experiment in search of a new, doom themselves to extinction.
   This year, more attention should be paid to the experimental construction, which allows to develop new technologies and promising innovations of industrial science, such as renewable energy sources, modern construction materials, new engineering systems. Experimental construction should be a real testing ground mining projects of the XXI century. That is why one of the main work was the logical conclusion of the contest on the new Moscow schools - schools, where it will form a new generation of Muscovites. In general, the experimental construction deserves special consideration with all the complex urban.
   Now the development of conceptual designs, defining system development capital. The main thing here, of course, Master Plan 2020. Its development was carried out on the basis of a comprehensive analysis of the urban development of Moscow, the outcome of the implementation of "Guidelines urban development of Moscow and the Moscow region for the period up to 2020" in the sectoral and regional sections. Taken into account peculiarities of the capitals of the world`s largest urban agglomerations, territorial and socio-economic linkages city and Moscow region.
   However, the strategy - give people good housing - can not be realized without addressing issues such as: ecology and economy of resources, ecology and conservation, retrofitting and modernization of enterprises, improving the design. In turn, all of these problems can be solved under the condition using the latest technologies, equipment and materials.
   With the abundance of all sorts of offers and limited financial resources arises complicated system task of selecting priority areas of support.
   It should be noted that in this task now, despite the difficulties, there has been a serious activity.
   Moscow hosts a number of interesting forums:
   International Congress of PBMC-98 "Spatial design in new construction and renovation of buildings and structures" at City Hall.
   In proceedings of the congress published 140 reports. These reports will contribute to the further development of the theory and practice of the use of the latest technologies of spatial structures in all areas of construction.
   International Conference and Exhibition "Buran" at City Hall. It was attended by about 400 scientists, experts, enterprises and organizations representing the aerospace industry from 8 states. The exhibition was launched in the lobby of City Hall, attended by more than 20 companies in Moscow and Moscow region. Seemingly far from the construction industry works on the question of "Buran". However, the sheer number of related developments made at a level above the world standards, shows that our attention to them a positive impact on the rise of various construction industry.
   International Conference "Critical technologies in construction", organized by the Russian Academy of Architecture and Construction, engineering universities Association and the Moscow State Construction University.
   This conference is held extremely useful work. Carried out:
   discussion and definition of priority directions of science and practice in construction, are critical from the standpoint of the development of construction activity in modern conditions;
   synthesis and evaluation of domestic and foreign experience in the scientific areas of concern of the conference;
   the rationale for the inclusion of identified critical technologies in construction list of critical technologies at the federal level a separate section, as priority areas of science and technology.
   By itself, the choice of specific priority areas of scientific and technological development and critical technologies is a complex scientific task that requires the participation of experts from the construction industry and academic economists. Is currently being finalized block critical technologies in construction.
   This is a serious and extensive work ultimately is permanent in nature and can be successfully implemented only in conditions of full analytical information specialists, allowing for valid comparison of different technologies. Facilitate the solution of this problem can be timely and competent publication of the results of relevant research through scientific and technological base edition. These publications can be a tool for science and technology policy in the construction industry.
