The regularities of the formation of matrix structure and its influence on the properties of ceramic wall materials made from non-sintering stiff technogenic and natural raw materials
have been discovered. It was found that the granulation of fine-dispersed technogenic raw materials with the application active sintered clay on the granules and pressing ensures the
formation of an ordered framework in the material. The scheme of formation of the matrix raw structure, which allows to increase the number of low-quality raw materials in the furnace
charge up to 80 wt.%. The features of transformation of raw molded structure into ceramic matrix composite after firing, while liquid melt is formed at the interface of granules, which is
introduced in the peripheral core region and form a matrix structure, enhancing the strength shard up to 30% after crystallization. It was shown that the formation of the matrix reduces
consumption of clay component up to 20–25 wt.%, this allows to reduce the content of clay minerals up to 6–8% in the composition of the charge, as contrasted with necessary amount
of 12–15% during plastic molding and 8–10% during semi-dry pressing. The resulting system from cores of non-sintered material and tightly sintered cover provides high strength and
performance characteristics of wall ceramic.

Influence of Dispersions of Multilayer Carbon Nano-Tubes on Physical-Mechanical Characteristics
and Structure of Building Ceramics

étekio al., LT–10223, Vilnius, Lithuania)
Main results of the study of influence of dispersions of multilayer carbon nano-tubes (MCNT) Masterbatch CW 2-45 on the physical-mechanical characteristics and structure of building
ceramics are presented. Dispersions obtained at the high-speed homogenizer and treated by ultrasound were used in studies. It is proved that the introduction of these dispersions in
the charge for manufacturing the building ceramics contributes to improving the homogeneity of ceramic matrix structure and reducing its porosity. The change in the structure of a
ceramic crock leads to improving mechanical indicators of ceramic samples before and after burning. It is established that introducing the optimal percent of MCNT in the amount of
0.001% of the mass formed makes it possible to modify the ceramic matrix, improving its physical-mechanical characteristics by 28–32%.

The studies for obtaining acid-resistant brick of common mineral resources, in particular from the brick-tile raw material deposits of the Republic of Tatarstan have been carried out. The
information about the stocks in the Russian Federation of the traditional raw material for acid-resistant ceramics - refractory clay have been given. To control the microstructure of the
ceramic, and thus the regulation of its density two methods are used: mechanical activation processing of raw materials and efficient use of modifiers. The suitability of the local brick
and The Republic of Tatarstan tile clay to produce new products have been demonstrated, such as acid-resistant ceramics for the chemical industry. As a result of pilot tests the prod
ucts which correspond to the direct acid-resistant brick, arch, radial classes A, B and C, mold classes A and B by parameters such us acid resistance, compressive strength, water
absorption, water permeability, thermal stykost have been obtained.
Keywords: brick-tile raw materials, acid-resistant ceramics, deposits, processing adds, pilot tests.

Development of Rational Parameters of Components of Foam Concrete Composition
A series of articles, devoted to Professor Gorchakov, development of his concept about the dependence of the structure, porosity and properties of building materials on the composi
tion continues. The development of the foam concrete of higher quality with a grade of average density of D400 is theoretically substantiated. This is achieved through the use of a
foaming agent with high-expansion foam and a high coefficient of application, multi-component modifiers of mineral and chemical nature in its composition. Special attention is paid to
obtaining the rational parameters of components due to the three-level optimization of the disperse composition of the foam concrete. The authors analyze the complex application of
micro-silica modifiers, super-plasticizer, hardener, fine-disperse slag, and modifier of MB group. It is shown that the three-level optimization is needed for ensuring the action of modifi
ers with synergy effect for improving the strength, reducing the shrinkage and heat conductivity of the foam concrete.
Keywords: foam concrete, optimization of disperse composition, mineral and chemical modifiers, porosity, foam expansion ratio.

Glued Wood Concrete from Timber of Soft Broadleaved Species
A.A. LUKASH, Candidate of Sciences (Engineering) (firstname.lastname@example.org)
Bryansk State Engineering-Technological University (3, St. Dimitrov Avenue, Bryansk 241037, Russian Federation)
The necessity of involvement of little-used wood of soft broadleaved species in recycling for expanding the raw material base of the construction industry is substantiated. Difficulties in
the production of wood concrete connected with the presence of extractive substances in the wood of soft broadleaved species that hinder the hydration of cement are outlined. On the
basis of the results of studies conducted, it is established that the use of known types of chemical additives doesn’t make it possible to produce the arbolite of required strength from
the wood of soft broadleaved species. The proposed cardinal solution for producing the wood concrete from the timber of soft broadleaved species makes it possible to replace the
binding cement with the water-resistant carbamide-formaldehyde glue on which extractive substances, containing in soft broadleaved wood, don’t have a negative effect. Maple syrup
and d-erythrose, containing in hogged birch chips, were identified by the method of IR-spectrometry. Regressive dependences, which determine the influence of wood and glue con
sumption on the compression strength of the laminated wood concrete, have been obtained.
Keywords: construction, arbolite (wood concrete), glue, production, strength.

The field of economic application of various types of fillers is expanding all the time due to permanently changing requirements for concretes concerning their operating qualities, appli
cation fields, physical-technical properties, durability conditions etc. Numerous studies have established that the most rational use of various types of fillers in the concrete greatly influ
ences on the technical characteristics of the concrete of building structures. Results of the studies of the concrete prepared with crushed fluxing limestone, which is a secondary prod
uct of metallurgical industry, are presented. On the basis of the study conducted, it is shown that the fluxing limestone can be used for products and structures of heavy-weight concrete
along with such fillers as granite macadam and natural gravel.

At present, a lot of hyper-plasticizers and super-plasticizers of various brands are presented at the Russian market of plasticizing additives. But the efficient use of these additives is
announced by the producers for compositions on the cement base mainly. This raises the need to study the work of modern plasticizing additives and their complexes in gypsum-
cement-pozzolanic compositions. The studies conducted make it possible to determine the effect of plasticizing additives and complexes on their basis on the rheological and physical-
mechanical properties of a composite gypsum-cement-pozzolanic binder, as well as to determine the optimal content of plasticizers in the composition of the complex additive. It is
shown that the introduction of plasticizing additives and their complexes makes it possible to improve the operating properties of products on the basis of gypsum-cement-pozzolanic
binders that results in improving the flexural strength by 70.3%, compression strength – by 82.7%, as well as improving the water resistance by 66% at slowing the kinetics of initial
structure formation. These results are achieved through the formation of the more dense porous structure of samples on the basis of the gypsum-cement-pozzolanic binder modified
with plasticizing additives. Thus, the total volume of pores is reduced by 9%, open capillary pore is reduced by 16.8%, open non-capillary pores is reduced by 1%, the volume of condi
tionally-closed pores is increasesd by 8.8%, an index of micro-porosity is increased by 0.38. This makes it possible to significantly expand the application field of products on the basis
of the modified composite binder when producing a wide range of building products.

Issues related to the development of high-quality concretes are considered. As a base of producing such concretes, the use of efficient chemical modifiers improving the rheological
properties of concrete mixes and reaction-active fine mineral mineral components of natural and anthropogenic origin facilitating the improvement of their physical-mechanical charac
teristics. A special attention is paid to the filler: the strength of coarse filler must be higher than the concrete strength by not less than 20% and maximum filler size should not exceed
8–20 mm. At present, significant experience in production of high-quality concretes is accumulated and it is necessary to implement it in practice. Results of the study conducted show
that the raw material potential of the Chechen Republic makes it possible to produce high-quality concretes of B 40 class, and if to expand the geography of North Caucasian Federal
District it can be possible to produce concretes of more high strength.
Keywords: high-quality concretes, composite binders, reaction-active mineral components, volcanic ash, ash of TPP, fractional filler.

Work of the Uralasbest plant shaft furnaces intended for drying asbestos ore and with different movement scheme and flows of gas-air material are considered. Some furnaces operates
countercurrent scheme and the other furnaces on the combined scheme when part of the gases from the furnace is fed through the bypass to the top of the shaft. On the basis of the
information obtained in the course of industrial research in shaft furnaces, the temperature distribution in the gas-flow and material flow adjustment shafts, data speeds and coolant flow
rate, humidity changes ore the thermal balance in the shaft furnaces ore with different moisture contents are compiled and analyzed. It is shown that the ore humidity less than 6% is
sufficient for the drying quality by supply of heat to only one horizon (the furnace is working on countercurrent scheme). At higher humidity heat input is required to at least two hori-
zons layers: top-filtered coolant down and bottom-up filtering coolant (the furnace works on the combined scheme). Shaft furnace disadvantages are noted and recommendations,
implementation of which will allow to optimize the drying process, and to obtain high quality final product with minimal cost of fuel and electricity.
