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...

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...

For many decades, urban development in our country reflects the socio-economic processes inherent in the administrative-command system of management, and are usually carried out extensive methods. With this approach to urban planning education was strongly influenced by "extensive" teaching methods directed for decades to minor changes of curricula. In the new social and economic conditions of urban education should reflect the dynamically changing requirements of urban planning and architecture, consider an order for new spatial forms and systems, materials, high quality living environment. Only in this way we will be able to develop urban planning school and do not allow to fade away and degrade the art of engineering.
   To improve urban education engineer urban planner based in the future, the need to audit the training process of building schools. The standard professional engineer town planner in the curriculum and work programs should be laid objective "ideology" generate a list of disciplines and their teaching. But the status of urban education, defining general and professional culture experts building complex structures and management of the city and, therefore, the academic policy in higher education should be increased considerably.
   Preparing engineers for urban development activities should primarily be based on the interpenetration of concepts of teaching in construction and architecture schools. To implement such a process should be based on a common understanding of urban objects is a collaborative architectural and engineering and ongoing joint efforts of architects and builders. At the same time, as we know, architects must understand the engineering conditions for the formation of urban and rural environment, the ability to interpret and translate into an art form these conditions. Engineers, planners, in turn, need to understand the functional and aesthetic problem of formation of urban environment urban and rural areas, to be able to address the needs of urban development in new technologies and formal methods to assess the quality of the designed environment, as well as support and ensure urban planning architect idea and implement it in kind .
   With this approach, urban planning training engineers urban planners in the construction and engineering universities will not copy urban planning training urban planners and architects, as a consequence, to simulate urban design that creates only the illusion of belonging to architectural creativity. In addition, it will provide the required complexity of the study subjects and thus fulfill the role of a city planner engineer in solving architectural problems of the organization environment at an urban design associated with the ability to professionally consider formalized factors.
   For knowledge about these factors need fundamental scientific and methodological basis and a new way of thinking, the basics of modern urban design as a single system, revealing functional and technological, physical, technical and complex technical problems of the urban planning ideas.
   The need to improve urban education in the new socio-economic conditions due to the methodological requirements to ensure the unity of thought and action in the design of complex, new attitude to built environments and new knowledge about her, not formed to the touch, and on models that allow purposeful and objective analysis to implement in practice and synthesis processes in nature and society.
   As is known, the projected environment for human life is described as a result of the interaction of spatial objects, which determines the order of transformation and intervention in nature, depending on the degree of use of the spaces closed construction (buildings and structures), open construction (urban areas in the ground level ), ground and surface areas (operated by flat roofs, platforms, etc.). Complex set of problems to be solved in the design of urban and rural settlements, according to this model, makes the development of an appropriate system of education. Moreover, the ideological aspect of the training should be focused not on self-sufficiency or priority and the objective trends of urban development, inclusion of these requirements in the formation of the exploited environment, the relationship of urban planning training of engineers and architects.
   Formation of the system of education caused by the principles of use in urban planning and "physical" design features of the interaction of objects presented model involving six combinations thereof. This fact should be the basis for development of curricula, programs, writing textbooks and manuals, guidelines, perform research.
   Suppose, as an object, requiring in accordance with the purpose of learning more in-depth study, adopted to IV - aerial territory. In this case, the objective of a core combination of three objects, which includes information on the above-ground areas concerning buildings and structures, the urban area in the ground level and earth.
