This paper studies the dependence of the ratio of prismatic strength (Rb) from cube strength (R) for high-strength concrete of classes B70 ... B110. Experiments were carried on the concrete cubes with an edge of 150 mm and prisms with a base 150x150 mm and a height 600 mm. The tendency to reduce the ratio Rb / R with increasing strength of the concrete is founded. A new relationship Rb = f (R) is offered

The paper proposes a new relationship for the analytical description of the diagram «b–b» for high-strength concrete of classes C55/67 ... C90/105. The formula developed on the basis of the accepted in EU relation of Sargin and agrees well with the experimental data. A new relation of the ultimate relative deformation of concrete from the strength is developed

Keywords: high-strength concrete, physical experiment, state diagram of concrete, the stress-strain dependence in concrete, the ultimate relative deformation of concrete

In our country creation of country housing real estate was slowed down due to the lack of necessary infrastructure, and also high level of cost at its creation. The main factor promoting development of mass low housing, existence of the corresponding infrastructure and necessary communications, and also in certain cases objects of social infrastructure is.
  It is impossible to forget and the problems arising by consideration of potential of development of low housing: infrastructure dilapidation; small number of free land fund; complexity of preparation of infrastructure of the territory; difficulties in search of financial resources; small susceptibility of branch to innovative processes.
  The scientific logistic model of the organization of the mass low housing construction, considering creation of necessary objects of infrastructure for building is offered. Now need of strategically planned coordination of business and the state is the only way to the solution of infrastructure and other tasks connected with development of low housing construction from developers and builders.

In recent years reconstruction of buildings and constructions became one of the main directions in the field of construction. Considering that at reconstruction capital investments it is significantly less, and payback is higher, than at new construction, the share of capital investments in reconstruction will increase.
It is necessary to apply intensive methods of repair and reconstruction of buildings and constructions as one-time costs of reconstruction and repair there are less than one-time costs of new construction in construction production. Considering a significant amount of the factors significantly influencing the organization of construction at reconstruction of buildings and constructions, previously before development of organizational and technological documentation it is necessary to prepare the list of the data necessary for the organization of construction works and to make their analysis which concerns the analysis of projects and the territory of a building site, including situational plans.

The article presents the results of calculations of reinforced concrete columns of high-strength concrete on the SNiP and SP. Compared the results with experimental data. The proposed adjustment formulas used with correction factors k and w resulting standard deviation of the bearing capacity of the columns from the experimental reduced more than four times.

Keywords: high-strength concrete, physical experiment, the correction factor calculation scheme undeformed

Discusses the main changes in kolorostike residential interiors in the period from 2003 to 2013 on the basis of analysis of works by Russian disigners. Whole Russian interior designers have lost some identity. Changing the color palette for the interior, executed in the style of "Art Deco", "modern", "fusion". Novation - "Ecostyle" and interiors in a light-color installations. Basically, the color palette has become more complex and sophisticated, perhaps less distinctive.

The article describes the methods of forming the program of technical and economic feasibility of reconstruction. The program is based on the technical and economic calculations which justify the need for its development. It is important to take into account the technical and economic indices which provide a minimal amount of construction works. During the development of technical and economic parameters, it is necessary to take into account the organization of construction, the terms of energy saving, heating, water supply, drainage and industrial waste water, human resources, the environment, the effectiveness of capital investments. All questions are considered for the perspective of the development of science and technology.

  Stability of sensors on the basis of inorganic oxide materials is one of the primary goals by working out of atmospheric air control devices. In this work long-term stability of a sensor response on the basis of the SiO2SnOxCuOy material to carbon oxide (II) exposure in a range of concentration 1-100 ppm is studied. It is shown that the sensor response differs high stability and reproducibility. Continuous heating within 21 days to working temperature (350°С) influence its value negligibly.

  We have investigated electrical and gas sensitive properties of gas sensor based on carbon nanotubes (CNT) and carbon nanotubes modified by metal oxides (such as tin oxide and silicon oxide).  Also we  have find out that modification of  CNT by  metal oxides helps to  improve film`s adhesion to substrate, decrease electrical resistance, recovery time, working temperature , enhance gas sensitivity in comparison with sensitive elements based  only on CNT or metal oxides. Moreover experimental results showed that properties of composite material depend on concentration correlation of solutions. As a result we can get highest sensitivity of sensor element by choosing optimal relation between concentrations of solutions.

  The algorithm of the research, including the technology of making the mycelium film on the resonator of bulk acoustic wave and gas medium with the given concentration was developed. As a result of the investigations the sorption sensitivity of extracts of the higher shiitake mushroom mycelium to the fume of volatile liquids and gases (acetone, ethyl acetate, formaldehyde, chloroform, acetic acid and hydrochloric acid, hexane, 10% aqueous ammonia) was studied. The study has shown that there are the processes of making the mycelium films, which keep the initial values of the resonant frequency and the quality factor of the resonator after moving off the fumes or gases. This work has shown that the mycelia films are very promising as a new material for gas selective coatings of electro acoustic sensors.
