Problems and possible ways of enhancement of a structure of a road reinforced concrete pre-stressed slab PDN with the purpose to increase its crack resistance under operating conditions
are described. Results of the visual inspection of tens of kilometers of roads paved with precast concrete slabs in Western Siberia are reported. The most frequently occurring
defects and damages in the slabs are described. To study the reasons for cracks formation in the course of operation, the analysis of stressed-strained state of slabs has been made
with use of the programming and computing suite ANSYS 14.0. It is revealed that the existing scheme of location of operating pre-stressing reinforcement of 3.503.1-91(1) favors the
development of transverse tensile stress in the slab’s end part and in zones adjoining it and may initiates the opening of longitudinal cracks in the process of operation under conditions
of multiple, repeated impacts typical for operational conditions of the road slab. A structural conception of a new slab PDNmAtV7 based on the optimization of reinforcement with the
purpose of reducing transverse tensile stresses near end surfaces of slabs caused by the preliminary squeezing by means of more uniform location of operating pre-stressing reinforcement
along the cross-section is proposed. This solution is patented and implemented in the production. Improvement of bearing capacity and crack resistance of the road slab
PDNmAtV7 has been achieved; it is very actual in connection with increasing the carrying capacity of transport and intensity of trucking and meets the requirement of a new GOST with
increased motor-car loading.

Results of the research in optimization of steam treatment of steel-fiber-concrete products are presented. The actual heat conductivity coefficients of steel-fiber concrete, which are
0.8–3.6 W/(m.oC) at different coefficients of three-dimensional reinforcement and the geometrical factor of steel fiber, are experimentally determined. Mechanisms of the distribution of
thermal flows and the numerical values of temperature gradients arising in steel-fiber concretes of different compositions in the process of heat and moisture treatment are revealed.
The dependence of reducing the compressive strength of steel-fiber concrete under the age of 28 days on the temperature gradient arising along the section of the composite under the
steam treatment. It is established that the destructive processes, which lead to the strength reduction, occur in steel-fiber concrete when the temperature gradient is over 0.6 oC/cm. On
the basis of the established dependencies, recommendations for defining optimal modes of heat and humidity treatment of steel-fiber-concrete products when developing the manufacturing
technology of massive monolithic and special structures made of steel-fiber concrete and hardening under natural conditions have been developed.
Keywords: steel-fiber concrete, heat and humidity treatment, heat conductivity coefficient, temperature gradient.

Bonded strength of reinforcement with concrete modified by superplasticizer “S-3”
S.N. LEONOVICH, Doctor of Technical Sciences, Foreign Academician of RAACS, N.L. POLEIKO, Doctor of Technical Sciences
Belarussian National Technical University (65, Nezavisimosty av., 220013, Minsk, Belarus)
The results of the effect of the compressive strength and age of modified concrete with superplasticizer C-3 and its modifications to the bond with the reinforcement of various profiles
and classes are presented. Established that the adhesive strength Rad of reinforcement and concrete significantly depends on its compressive strength Rc. This dependence is linear and
is the same both for normal concrete and for modified concrete, although its numerical parameters are different. Particularly, with increasing of concrete compressive strength limit
from 30 to 70 MPa the average value of adhesive strength Rad for smooth reinforcement in modified concrete increases in 1.5 times, and in the normal – 1.36 times. With increasing
of compressive strength Rc adhesion strength of reinforcement with concrete increases, and its relative value Rad/Rc reduces, because along with it reduces the relative tensile strength
Rt/Rc. Integral adhesion strength essentially depends on the tensile strength Rt and is determined by the mechanical engagement of free length of reinforcing bars with mortar part of
concrete. Adhesion strength of periodic profile reinforcement with concrete is much higher. Also it can be seen the increase of adhesive strength Rad with decreasing of rods diameter,
especially in periodic profile fittings. Thus, periodic profile surface relief does not affect the adhesive strength with concrete.
Keywords: modified concrete, modificator, class of concrete compressive strength, class of reinforcement, diameter, bonded strength, profile of reinforcement.

Complex siloxane coating for superhydrophobization of concrete surfaces
Traditional PC based concrete, generally, is hydrophilic material. This characteristic explains reduced durability, especially, for pavements. To produce the road concrete with waterrepellent
properties the hydrogen siloxane emulsion is developed. Possibility of using of hydrogen-containing siloxane additives in complex with a small content of submicro-sized particles
to provide with super-hydrophobic characteristics for concrete is considered. The technology of production and application of the emulsions for cement concrete, that allow forming
and varying the hydrophobicity with directed designing of hierarchical roughness and the surface modification jointly. This fact gives opportunity to produce over-hydrophobic and
super-hydrophobic concrete with water-repellent characteristics, high values of contact angle and low roll-off angle that can be used in road construction as material with good durability
Keywords: contact angle, hydrophobic concrete, superhydrophobicity.

Quantitative parameters of basic composition factors ensuring the possibility to obtain (when using qualitative materials) cement concretes for road and airfield pavements when the
value of W/C not more than 0.34 are determined. Proposals on the adjustment of the normative requirements to the value of compressive strength class of these concretes not below
В45 are formulated on the basis of the analysis of five key normative documents. Ratios of tensile strength at bending and compressing are clarified on the basis of results of the study
of concretes with compression strength within the range of 40–120 MPa. It is shown that concretes of Btb 5.2, prospective for airfield pavements, require special solutions for regulating
the value of elasticity modulus, which predetermines the relevance of research in this direction..
Keywords: concrete for road and airfield pavements, normative requirements, ratio of tensile and compression strengths at bending, frost resistance, modulus of elasticity.

Investigations of strength and deformation properties of fine graded sandy concretes (FSC) with the purpose to reveal the most suitable dependences for expression of the curvature
parameters of the diagram of FSC tensile in the course of axial tension through the compressive and tensile strengths of concrete were conducted. Studies were conducted on the
experimental samples in the form of «eights», their compositions were added with the fiber as an elastic element. The samples were tested in a specially designed device which made it
possible to carry out the quasi-static loading and determine the tensile deformation of the sample. In the course of analysis of experimental data new dependencies for calculating the
curvature parameters of the diagram of FSC tension were obtained, adjustment coefficients for these dependencies, values of which are recommended to use in calculations according
to the diagram technique, were selected.

Magnesium oxychloride boards: Problems of Production, Use and Prospects of Development
A.A. ORLOV, Candidate of Technical Sciences, T.N. CHERNYKH, Candidate of Technical Sciences, L.Ya. KRAMAR, Doctor of Technical Sciences,
South Ural State University (National Research Unversity) (76, Lenina Ave, Chelyabinsk, 454080, Russian Federation)
Results of the study of production of magnesium oxychloride boards (MOB) and their use for interior finishing are presented. An analysis of the normative base and reasons restraining
the growth of production of magnesium oxychloride boards is conducted. These reasons are technologies insufficiently efficient and unadapted to Russian conditions; the absence of
integrated normative documents for production and use of magnesium oxychloride boards; deficiency of a magnesium binder in RF; instability of magnesium oxychloride cement properties
produced in Russia; swelling and buckling of MOB in the course of lasting and/or repetitive wetting and low durability when operating under wet conditions; release of harmful
and hazardous substances under fire conditions; lack of specially developed complete systems of MOB installation. Ways to improve the quality of materials and technologies of their
production are proposed. It is shown that MOB have a very high potential for development and improvement of their quality, and modification of their structure and properties is a promising
direction of works in the field of building materials science.

Comparative tests of different types of diffusion membranes with the use of the artificial aging method by means of exposure to ultraviolet radiation and cyclic influence of
different temperatures are presented. The dependence of strength indexes and waterproofing properties on time of exposure is shown. On the basis of experimental data it is
established that the durability (service life) of wind-protective membranes made of flash-spunbond polyethylene (produced in Luxemburg) is over 20 years of operation. The
following wind-protective membranes – a three-layer microporous membrane of Russian production and three-layer microporous membrane with two layers of spunbond
polypropylene of foreign production – are insufficiently resistant to climatic influences. Durability of these membranes according to the results of accelerated tests is less
than 10 years. The difference in the results of accelerated aging of polymeric materials is associated with different structure, thickness of a functional layer and the presence/
absence of antioxidants and UV-stabilizers, which protect the polymer from destruction under the influence of temperature and UV- radiation. In connection with this it is reasonable
and actual to determine the stability of polymeric membranes used in construction of roofs and wall enclosing structures to the UV-radiation and high temperature.

Results of the study of influence of vanadium-containing waste on the processes of sintering of a ceramic body from the slurry part of waste of the iron ore enrichment are presented.
It is established that the addition of vanadium slag leads to changing the volumetric coloration of ceramic products, and vanadium oxide contained in it intensifies the processes of
sintering into the final stage of the silicate melt curing and serves as a catalyst in mineralization of ceramics on the base of iron ore waste, the most typical of which are chain silicates
of augite, melilite and wollastonite. Methods of petrographic analysis, scanning electronic microscopy, spectral analysis and X-ray diffractometry are used for studying the structure
and phase composition of ceramic materials on the basis of slimes of iron ore waste with corrective additives. The introducing of additives leads to formation of a ceramic body
with an expressed glass- crystalline structure characterized by porous texture. In this case the pore space is fully or partly filled with a cryptocrystalline substance that increases the
strength of ceramics.

Results of development of the construction complex and building materials industry in 2013, the forecast for 2014
A.A. SEMENOV, Candidate of Sciences (Engineering), General Director,
OOO “GS-Expert” (18, off. 207, 1st Tverskoy-Yamskoy lane, Moscow, 125047, Russian Federation)
The assessment of the state of the construction complex and building materials industry is presented. It is noted that despite the fact that official statistics data are more optimistic than
the expert evaluation, data of 2013 indicate the stagnation and possible beginning of lowering of basic indicators in the construction industry. As a result of 2013, investments in fixed
capital by the «Construction» type of activity decreased by 1.5% comparing with the previous year (at comparable prices). The commissioning of housing was 69.39 million m2, that is
by 5.6% more than in 2012. Mortgage lending plays a major role in the development of housing construction. The average growth of volume of building materials production by 0.3% at
the end of 2013 was achieved mainly by increasing production volumes of certain types of materials used in the construction of individual housing and renovation of existing buildings
and structures. Programs of road and housing construction, financed from the budgets of different levels, as well as the predicted growth in construction in some segments of commercial
real estate may become the main drivers of the growth of construction in the near future.

Framework technology of fired material with filler on a vitreous binder
Large fillers are widely used in building materials on non-fired binders. A possibility to use large fillers in fired building materials is connected with the solution of the problem of producing
the non-shrink fired binder which possesses strong adhesion to the surface of filler grains. The article offers a method for the synthesis of such binder from liquid glass and
sodium-lime-silicate glass powder in the process of material heat treatment. For molding the product with large filler it is proposed to use the framework technology, when binder components
are used consistently over time in the process of gluing the framework of filler grains with liquid glass and impregnation of the hardened framework with an aqueous suspension
of glass powder. The framework technology makes it possible to obtain the large-porous structure of material and reduce the consumption of binder components. Impregnation of
the hardened frame and burning of the product are carried out at temperature of 740–780оС without moulding accessories. Using the proposed technology, the material with a filler of
expanded clay gravel on the non-shrink vitreous porous binder with strong adhesive contacts with the surface of filler grains has been obtained. Physical-mechanical characteristics of
the material make it possible to use it for manufacturing heat insulating or structural-heat insulating products for building purposes in the form of blocks or slabs.
Keywords: large filler, liquid glass, sodium-lime-silicate glass, burning.

The influence of the content of phosphorous and chlorine containing plasticizers on heat resistance and smoke-forming capacity of polymeric construction materials (PCM) is considered.
Thermo-chemical characteristics of phthalate and phosphate plasticizers at the limit of candle burning are determined. It is established, that phosphate plasticizers practically
don’t reduce the fire hazard of materials on the basis of epoxy oligomers and synthetic rubber and increase the flammability of PVC materials. It is shown that the chemical
nature of phosphate plasticizers significantly influences on the smoke-generating capacity of PCM. It is revealed, that chlorinated paraffines more efficiently reduce the flammability
of plasticized PCM.
Keywords: oxygen index, coefficient of smoke-generating, phthalate and phosphate plasticizers, temperature of ignition and auto-ignition, chlorinated paraffin waxes.

Biostability of Wood in the Presence of Phenyl Borates
The biostability of samples of pine wood impregnated with biofire-retardant compositions which contain phenyl-boric acid and mono- and diethanolamine is studied. The surface
of wooden samples is contaminated with the suspension of spores of wood destroying mold fungi. As a result of tests it is established that the biostability of biofire-retardant
compositions FBK+MEA (1:1.5%) and FBK+DEA (1:2.5%) is 90%, biostability of FBK+MEA (1:1.1%) – 100%. The durability of protective action of modifiers developed is not less
than 10 years.

Structure and properties of a modified wood-polymeric composite on the basis of polyvinylchloride
The authors have developed a polyvinylchloride composition on the basis of wood flour (over 50 mass%) which has superiority over industrially manufactured analogues. The interaction
between components in the “wood flour – polyvinylchloride” system modified with silica sol and recommended for generating highly filled wood-polymeric composites for construction
purposes is assessed by the electronic scanning microscopy. It is established that a bonding agent, silica sol, concentrates in the “collectivized” boundary zone. Increasing the content
of wood flour in the polymeric composition (from 50 up to 200 mass-particles per 100 mass-particles of PVC) leads to reducing the thickness of the loosened boundary layer
(almost by a factor of ten) and reducing the temperature of vitrification. The dependence of main technological and operational properties of developed composites (tensile strength,
thermal stability and processability) on the thickness and structure of boundary layers is revealed.
Keywords: nano-modification, polyvinylchloride, silica sol, boundary layer.

Magnetic inspection of ferro-admixtures of feldspar: assessment of a factor of following involvement of particles

Advantages of the use of the new method of magnetic inspection intended for determining the content of ferro-admixtures in different raw components used in the course of manufacture
of ceramic tiles, glass and other construction materials are described. It is shown that at magnetic inspection in removable admixtures, besides ferromagnetic admixtures, the
involved particles of the medium analysed are also present. In contrast to quartz sand a distinctive fracture is observed on the mass-operational characteristic of magnetic inspection of
feldspar admixtures that prevents the use of the same calculation formulae used for quartz sand. On the basis of the analysis of histograms of distribution of ferro-particles and
involved particles of feldspar in the sediment extracted from the feldspar, the fractional presence of ferro-particles is assessed as 72%. The appropriate analysis of sediments extracted
in the course of magnetic inspection is made separately for the parts of the obtained mass-operational characteristic of magnetic inspection: before and after the fracture. It is established
that fractural presence of ferro-particles is 87% and 54% in this case. This indicates the need for the use of correction factors when determining the content of ferro-admixtures
in the medium analyzed by the method of magnetic inspection.
Keywords: mass-operational dependence, ferro-particles, following involvement of particles, histogram of quantity, histogram of volume.
