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...

 Line  method  of  mass  reconstruction  of  a  five-story  building.  (END)

Digital encryption events and works in the computer allows you to store information about the material and technical resources, the duration and cost of the work, which provides operational control and adjust the progress of reconstruction works. Calculation of network switching times by a known method of calculating network schedules at any stage of construction defines all data on the network works similar to the data that is obtained by calculating the common network diagrams.
   For organizing the construction of flow at the site is necessary to identify the individual process units or areas zahvatki, lines with complete technological cycle construction. Differentiation of the object on the process units and plots made to the size, scope of work allowing to provide for the optimal minimum number of performers with univariate process sequence execution. Technology and organization of construction works on this site, the site worked on technological normals which are: the composition of processes, which are complex to produce the finished product (assembly area), the degree of partitioning processes the sequence of their implementation on the host site without breaking technology and loss of productivity; necessary technological breaks their location and duration, as well as the duration of each process on the site. Next, we construct a sequence diagram network of works on this site, plot, house.
   To develop an integrated flow sequences for reconstruction of the entire building block initially developed technological object and normal network cyclogram conversion facilities with a combination of construction processes in time and consistent transition teams performers from one production area to another.
   For the formation of the annual programs of the construction organizations cyclogram network object larger and they are shown the beginning and ending spetspotokov works on objects. Annual cyclogram built on the most critical object streams - boxes reconstruction buildings. Later, during the period of implementation may prompt conversion of any specialized streams flow.
   Formation of complex annual flows and their number are determined depending on the capacity building organizations.
   In accordance with the generated annual flows are plotted complex needs logistical and financial resources.
   Use of computer programs monitor and adjust network switching times during the reconstruction works allows to determine the failures occurred, predict consequences, and take prompt measures to normalize the flow.
   The project resulted in the reconstruction of a five-storey residential block number 367 in Belgorod line method over five years (5 stages), can be obtained in an updated modern social, technical and aesthetic aspects of architectural and residential district high-rise buildings, as shown in the figure.
