Influence of the Wollastonite Additive on the Structure of Wall Ceramic Materials from Technogenic and Natural Resources
The results of investigations of the possibility of application of wollastonite ore as a corrective additive in ceramic charge based on technogenic and natural materials is offered in cur
rent paper. It has been established the total number of acicular particles after grinding wollastonite ore and the dependence of their shape on the size fractions. It was revealed that the
grinding of wollastonite additive leads to decrease of the firing shrinkage for all types of used raw materials. The influence of fine wollastonite ore additives on the structure formation of
wall ceramic materials produced from the tailings of the slimy iron ore, waste coal and Novokuznetsk’s loam were found. During the liquid phase sintering process, wollastonite acicular
particles perform the reinforcing role and influence positively on the process of structure formation of pottery clay raw materials and waste coal. The introduction of wollastonite addi
tives in charge of slimy iron ore wastes impairs the physical and mechanical properties of wall ceramics within the absence of clay minerals.
Keywords: iron ore wastes, coal wastes, wollastonite ore, structure forming, wall ceramic materials.

Heat-Insulating Materials and Products on the Basis of Tripolis of Potanin Deposit
Production of granulated foam materials on the basis of onestage technology from tripolis of Potanin Deposit without preliminary melting in glass has been organized at “Baskey
Ceramic” Enterprise in Chelyabinsk Oblast. Production of heatinsulating products is based on the synthesis of hydrated polymer sodium silicates (Na2O∙mSiO2∙nH2O) in alkali composi
tions on the basis of siliceous rocks with the following thermal processing of semifinished product and obtaining of a final product – porous granules of cellular structure. Depending
on conditions of tripoli treatment, “Baskey Ceramic” produces granulated heatinsulating material with different poured density from 180 up to 400 kg/m

Foam Glasses of Cullet – Clay – Sodium Hydroxide System: Compositions, Structures and Properties
A new approach to the design of compositions of multicomponent aluminoosilicate batch for producing the foam glass with improved strength characteristics is considered. Prediction of
structure and properties of foam glasses on the basis of cullet, clays, alkali component and gasforming agents is made with the use of physicalchemical methods of study: Xray phase analy
sis, electronic microscopy as well as with the involvement of the method of mathematical planning of experiment. Study of the phase composition of the original clay raw materials and foam
glass has been conducted. It is established that in case of foam glasses of the cullet – clay – sodium hydroxide system the incorporation of 2–3% of carbonate and carbon gasforming agents
into the batch (over the dry batch mass) leads to the increase of average density of foam glass and, as a consequence, its strength. When using limestone improving the physicalmechanical
properties of foam glass can be explained by crystallization of omphacite. When using anthracite the growth of density and strength of foam glasses is mainly due to the improvement of
porous structure of the material. The results obtained contribute to the expansion of the sphere of foam glass application, as a structuralheat insulating material, for example.
Keywords: foam glass, limestone, anthracite, omphacite, Xray phase analysis.

Methodological Principles of Synthesis of Foam-Glass-Crystal Materials According to Low-Temperature Technology
The research in possibility to regulate the process of producing foamglasscrystal materials from lowtemperature quenched cullet by means of optimization of the composition and
structure of the material is presented. Optimal values of validity criteria of compositions of batch, granulates, and foamforming mixes for producing the finished material are estab
lished. It is shown that the strength of foamglasscrystal material depends on its microand macrostructures stipulated by viscosity and temperature conditions as well as on the pres
ence of crystal phase particles in the interpore partition.

Deformations and Durability of Concrete During Cyclic Freezing
Theoretical substantiation and experimental verifications of reasons for frost aggression in concrete are presented. Features of effect of freezing in salt solutions on the cement stone
and concrete are considered. It is shown that the requirements of standards to ensure the air entrainment in the course of production of frostresistant road and hydraulic concretes are
not always effective for highstrength concretes. It is established that to ensure the frost resistance of highstrength concretes without air entrainment, the low watercementratio and
the use of active mineral additives which favour the formation of lowbasic calcium hydrosilicates of the gellike structure resistant to leaching are necessary.
Keywords: road concrete, hydraulic concrete, frostresistance, cyclic freezing and thawing, air entrainment, ice formation, porosity, deformation, active mineral additives.

An analysis of requirements to properties of modern reinforced concrete structures operating under the influence of reversal and dynamic loads shows that low tensile strength of con
cretes is a system shortcoming which predetermines their limited operating reliability. The most modern method of reducing negative sequences of this shortcoming is dispersal rein
forcement of concretes with fibers. Results of the experimental studies of the influence of dispersal reinforcement with synthetic fibers on the bond strength of bar metal and glassplas
tic armature with concrete and fiber concrete are presented. It is shown that in spite of the fact the incorporation of conglomerate structure of synthetic fibers into the concrete compo
sition leads to reducing its compression strength the bond between bar reinforcement and fiber concrete increases. This result makes it possible to predict the increase in energy
consumption for destruction of building products made of fiber concrete reinforced with bar reinforcement.
Keywords: concrete of conglomerate structure, fiber concrete, bond strength, metal bar reinforcement, glass plastic bar reinforcement.

The use of Expanding Additives in Steel Fiber Concrete
Results of the study of influence of expanding additives on deformations and strength properties of steel fiber concrete are presented. It is established that the introduction of various
expanding additives multidirectionally influences on deformations of steel fiber concrete depending on the matrix strength and reinforcement coefficient and makes it possible to pro
duce the composites with their own deformation within the limits from 0.084 up to 0.271 mm/m at the age of 28 days. Dependences of strength properties of steel fiber concretes with
expanding additives on the values of finite deformations are determined. The optimal complex use of expanding additives (10% of cement mass) and steel fiber in composite composi
tions makes it possible to increase additionally their compressive strength up to 18.4% and the bending tensile strength up to 16.3%. The effect obtained is explained by the occurrence
of a prestressed fiber frame in the matrix of composite material, formation of which is possible under certain conditions.
Keywords: steel fiber concrete, expanding additive, deformations, prestressed fiber frame.

At present foamed polymer materials occupy an extensive sector at the world plastic market, they total up to 10% of the total volume of polymer resins consumption. The world market
of foamed materials continues to actively develop, at that foam polystyrene is one of the most popular foamed plastics after foam polyurethane. Its part is a quarter of the world
demand. A change in operational properties of foam polystyrene, which is widely used in construction, can take place as a result of photooxidative and thermaloxidative processes
leading to change in the molecular mass and molecularmass distribution. In addition, the reason for changing operational properties can be structural changes which occure during the
time and under the effect of relatively low temperature. The successful use of any polymer material under various conditions depends on its ability to preserve its operational properties,
i.e. on its durability.
Keywords: foam polystyrene, polymer heat insulation, oxidative destruction of polymers, thermaloxidative destruction.

Condition of Lightweight Concrete Walls Operating in the North
Data on the condition of lightweight concrete in enclosing structures of buildings on expiration of their design life are presented. Monitoring and taking of readings of temperature and
humidity in the wall structure were made during 10 years. A significant increase in air humidity inside the every structure and appearance of condensate in cold winter months even in
the structure of material little absorbing the moisture is revealed. Changes of an enclosure structure on the test stand shows that the homogeneous structure of ceramsitegas concrete
more meets its purpose under conditions of the North. Comfort conditions for living are saved in apartments during decades. This material can be used for manufacturing enclosing
structures. Variants are offered, if necessary, to reduce the density and increase the heat resistance of walls.
Keywords: ceramsitegas concrete, heat resistance, foam polystyrene, microfiller, moisture content, condensate.

Simulation of Heat-Mass Transfer in the Gas-Solid System at Dowel Joints of Timber Structures Elements.
Part 2. Dynamics of Temperature Fields at Arbitrary Law of Changes of Air Environment Temperature
Physical and mathematical models of heat transfer in the timber of dowel joint are presented. The physical model is based on the idea about timber as a colloid capillaryporous body. It
is shown that due to the significant difference of thermophysical properties of a metal dowel and timber (above all, the coefficients of heat conductivity and temperature diffusivity dif
fer by an order and more) the change of dowel’s temperature takes place in accordance with the change of operational air environment; at that, temperature profiles determined by the
thermal conductivity law are formed in the wood. The mathematical model is based on the nonlinear differential equation of heat conductivity of parabolic type with the nonlinear
boundary conditions of the first and second kind and on the general function which determines the initial temperature distribution. In case of the use of the “microprocesses” method
the problem is linearized, its numericalanalytic solution becomes possible. Graphic illustrations of model calculations are presented.

Producing of Synthetic Gypsum from Dolomite and Sulfuric Acid and Its Recrystallization in α-CaSO4∙0,5H2O
in Magnesium Sulfate Solution
An analysis of the raw materials base for producing gypsum binders in the Republic of Belarus is presented. In connection with the absence of natural raw material in Belarus and diffi
culties of technical and economical character of phosphogypsum processing in gypsum binder the reasonability and prospectivity of producing the synthetic gypsum from dolomite by
means of its sulfuric acid decomposition with obtaining of high quality CaSO4∙2H2O and MgSO4 solution is substantiated. Availability of high quality dolomite and cheap sulfuric acid
makes it possible to produce from them synthetic СaSO4∙2H2O and magnesium sulfate which is used for magnesia cement preparation. In the course of structurally controlled synthesis,
parameters of the process ensuring the production of desired product of required morphology have been developed. Values of Н2SO4 concentrations, the order of reagents discharge,
temperaturetime parameters of the synthesis are optimized. Technological parameters of the process ensuring the recrystallization of gypsum into αCaSO4∙0,5H2O in 25% solution of
magnesium sulfate with obtaining the desired product of G8–G10 mark suitable both for construction and medical application are presented.
