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.

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...

In the development of academic approaches to retrofitting first mass and neighborhoods (see number 1, 1999)-AB AIIST RAASN developed a concept model and technical solutions for self-supporting reconstruction of dwellings without relocation of tenants, the essence of which consists in the superstructure with attics simultaneous modernization of engineering systems, insulation of facades and window fillings, installation of elevators (where necessary), repair work in the stairwells, installation of metering devices, monitoring and control of energy expenditure.
   Modernization or reconstruction of residential buildings can be carried out: without resettlement of residents or temporary resettlement of residents from the upper floors and return them to the upgraded apartments in the same house.
   It is envisaged to implement the following basic principles:
   a material interest in the improvement of living conditions and social protection of citizens reconstructed houses;
   maximum safety of housing and extending the life cycle of residential buildings;
   reduce the cost of construction of new apartments and self-sufficiency programs and projects for the reconstruction of residential development in the economic interest of investors;
   minimize operating costs, particularly for heating and hot water supply;
   architectural renovation of homes and buildings;
   Environmental safety and security of buildings and residents from extreme natural and man-made influences.
   Selecting methods of modernization and reconstruction of buildings is determined by common goals and objectives of the development of the existing housing estate, architectural and construction solutions buildings, their degree of wear and tear, the composition of tenants, investment characteristics, the relation of social apartments and commercial purpose.
   On space-planning decisions attic floors (their location relative to overbuild residential building height (number of levels), relative to the width of the house can be mounted above, the configuration of the roof of the attic, attic space relationship with the communication structure of the building), they are divided:
   by position relative to overbuild the house - on the top floor at home, and possibly to attach volumes (bay windows, risalits) on the top floor of the house with the inclusion of the latter in the space-planning structure of the attic; overbuild additional floors above;
   the number of storeys - siblings and duplex, in turn, can be located with the layerwise apartments, duplex apartments and location combined;
   the width - within the width of the existing house, larger width due to console departures;
   Configuration of the roof - with a triangular profile tacks profile, symmetrical or asymmetry indices stingrays ends can be resolved vertical, inclined or a broken outline;
   Liaison with attic space communication structure of the building - adjacently to the ladder or staircase-lift assembly, the unit corridor.
   Ability to add-ins and devices attic of a species depends on the type builds on building stock carrying capacity of its basic structures, provide the required insolation premises as the reconstructed building and surrounding houses.
