The situation analysis of production of wall silicate products as of the first half of 2016 is presented. It is noted, as a disturbing trend, not only the significant reduction in production
output but also reduction in the number of operating enterprises of the industry. It is also revealed that in 2015–2016 silicate wall materials show the most serious decrease in produc
tion rates among the single-piece wall materials. The most significant drop in production volumes is recorded in the Northern Caucasus, Ural, and Siberia Federal Districts. In January–
June of 2016 the growth in the output of silicate wall materials was observed only at three factories from 67 really operating.

Kazan State University of Architecture and Engineering (1, Zelenaya Street, 420043, Kazan, Republic of Tatarstan, Russian Federation)
Due to the increasing competition at the market of wall materials manufactures, the problems of improving the quality of products can’t be solved without re-equipment of factories.
Replacement of operational equipment which don’t provide an adequate level of contemporary technology and selection of the new import equipment widely presented at the mar
ket, raise the problem of compatibility with local materials, one of which is lime. Replacement of the press equipment only which in turn needs the molding mixture of stable com
position can’t be considered as re-equipment. The analysis and results of the study of the influence of quick-slaking lime on the equipment operation in the processing chain are
presented. Data on the influence of lime activity, a binder and their content in the mixture on the quality of molding mixture and conditions of mixing in the course of mixture prepa
ration are presented. The correct placement of modern equipment in the processing chain with due regard for the quality of raw components is the key to successful operation of
the entire production.

Belgorod State Technological University named after V.G. Shukhov (46, Kostyukova Street, 308012 Belgorod, Russian Federation)
The possibility to expand the traditional raw material base of autoclave silicate materials due to clay rocks of unfinished stage of mineralization, which are widespread in the Russian
Federation and in many countries of the world as well as in large quantities get in the zone of mining operations when extracting minerals, has been established. The use of these rocks
makes it possible to control the processes of structure formation of autoclave materials of a new generation. In this case, new formations of different compositions and morphology,
which form cementing compounds of optimal composition that ensures high physical-mechanical properties of products, are synthesized. The nomenclature of efficient autoclave prod
ucts including wall, finishing, structural-heat insulating, heat insulating, and acoustic materials is proposed.
Keywords: clay rocks, raw base, autoclave silicate materials.

Problems of the efficiency of micro-, nano-modification of the hydrothermal-synthesis hardening system and the structure of silicate stone are considered. The interconnected and joint
regular manifestation of actions of nano-technological principles “top – down” and “bottom – up” during the structure formation of silicate autoclaved materials is shown. Kinetic char
acteristics of the heterogenic process of formation of the hydrothermal-synthesis hardening depending on technological factors are studied and quantitative assessed. The comparative
analysis of the efficiency of micro- and nano-modifying process of structure formation, when regulating main technological factors, shows that at rational combinations and values of
factors related to the principle “top – down” and “bottom – up”, the synthesis of cementing substances can be accelerated by two-three times. The systematics of means from the
“nano” arsenal for possible improving the efficiency of processes of silicate stone structure formation according to criteria Е, τ, R is presented.
Keywords: hydrothermal-synthesis system of hardening, micro- and nano-modification, efficiency of structure modification.

Theoretical and experimental studies for revealing the factor of influence of natural carbonization (under the impact of atmospheric carbon dioxide) on the long-term deformability of
bending reinforced concrete elements made of gas-ash concrete of autoclave hardening are presented. It is established that the main reason for increasing long-term deflections of car
bonized bending elements comparing with non-carbonized ones is a significant influence of the carbonization factor on the value of concrete creep in the compressed zone. It is shown
that in the case of the long-term loading the method of Professor I.I. Ulitsky based on the theory of aging can be used for determining deflections of cellular concrete bending elements
at any moment of time and predicting their maximum values with due regard for carbonization, if the values of creep characteristics obtained on concrete prisms are known. It is recom
mended to take into account the influence of natural carbonization when calculating the long-term deformability of cellular concrete bending elements by adopting the value of the fac
tor ν, characterizing the concrete creep in the compressed zone, as equal to 0.1 instead of 0.2 at relative humidity of the environment of 40–75%.
Keywords: autoclave cellular concrete, carbon dioxide, carbonization, creep, bending elements, long-term deformability.

The problem of receiving the key component of foam concretes production – a foaming agent – is considered. Two approaches to its solution are proposed. The first one is the use of
mycelial waste of the bio-chemical industry containing large amounts of proteins of a microbic synthesis. Waste of antibiotics production is used as mycelia waste. The second one is a
synthesis of proteins with the help of microorganisms on the food industry waste. These wastes are curd and cheese whey, distillery stillage. For enrichment of these wastes with pro
teins, microorganisms were selected and conditions of their cultivation on wastes were developed. The base of the foaming agent is a protein hydrolysate of microbic synthesis.
Conditions of the protein hydrolysis are shown. Properties of foaming agents have been studied. Foam expansion ratio of these foaming agents is 18–23, water segregation per an hour
– 0%, the foam stability factor in the cement mortar – 0.9–0.92. The quality of the developed foaming agents is not inferior to the existing analogues, but cheaper. Compositions of
foam concretes on the basis of these foaming agents have been developed, and their properties have been investigated. It is established that qualities of foam concretes on the basis of
foaming agents obtained are not inferior to foam concretes produced on the basis of the foaming agent “Penostrom”.
Keywords: foaming agent, microbic protein, hydrolysis, foam concrete.

The Use of Micro-Disperse Additives for Accelerating Cement Hardening
Yu.R. KRIVOBORODOV, Doctor of Sciences (Engineering),

Dmitry Mendeleev University of Chemical Technology of Russia (20, Geroev Panfilovtsev Street, 125480 Moscow, Russian Federation)
Results of the influence of artificially synthesized micro-disperse additives of crystalline hydrates on the basis of calcium sulfoaluminetes on the properties of cement stone are present
ed. The efficiency of using the rotary-pulsation apparatus (RPA) as an activator-homogenizer for obtaining micro-disperse additives is revealed. The possibility of accelerating the hard
ening of cement stone by means of introducing micro-disperse additives in its composition is shown. It is established that in the presence of micro-disperse additives of crystalline
hydrates in cement stone, the phase composition of hydrate new formations changes in the direction of increasing the amount of calcium hydro-silicates. This fact is confirmed by
increasing the degree of cement hydration, the amount of bound water in all periods of stone hardening. It is proposed to use micro-disperse additives, which play the role of seeds for
crystallization of ettringite and calcium hydro-silicates, for increasing the strength of cement stone at early stages of hardening.
Keywords: cement, hydration, hardening, additives, strength.

Results of the study of physical-mechanical characteristics of disperse-reinforced fine concretes with poly-functional modifying additives are presented. Methods for complex disperse
reinforcement of fine concretes with non-metallic fiber of different types are proposed; they make it possible to directionally form the structure of such composites at various scale lev
els. The influence of fibers of three types has been studied. They are polypropylene multifilament and polyacrylonitrile synthetic specially processed fibers with the cutting length of
12 mm, as well as basalt microfiber modified with astralenes with the length of 100–500 microns. As modifying additives, micro-silica condensed and compacted, high active metaka
olin, and a hydro-isolating additive in the concrete mix are used. An analysis of the study of the saturated D-optimal plan is made with the help of three-angle diagrams of Gibbs-
Rosebom built according to polynomial models of “mix I, mix II, technology-properties” types which make it possible to trace the influence of 6 variable factors in the two-dimensional
space The feasibility of the complex use of modifying additives and disperse fibers, including nano-modified, for improving the properties of fine concretes is substantiated.
Compositions with the best complex of elastic-strength characteristics are identified.

The review of methods for manufacturing nano-concretes in the nowadays building industry is presented. The first method is a finish grinding of traditional Portland cements until nano
size values and producing nano-cements. The technology of producing this nano-cement is based on the combination of mechanical-chemical activation of Portland cement grains in
the presence of modifiers with the grinding of materials until the nano-size state. The second method is introducing nano-particles in Portland cement. Micro-silica is produced as a by
product in the course of producing the elemental silicon and silicon-containing alloys and provides the creation of super-strong and durable concretes. Introduction of the carbon nano
tube dispersion accelerates the hydration process, regulates the porous structure of nano-concrete. The presence of nano-particles suitable for modification of concretes is detected in
some natural minerals and industrial waste. The third method is the synthesis of nano-particles directly in concrete mixes with the use of initial substances – precursors. Nano-particles
of the silicon dioxide obtained by the so-called sol-gel technology show high efficiency.
Keywords: nano-concrete, nano-cement, nano-particles, precursor, sol-gel technology.

A binding capacity of environment friendly high-disperse saponite-containig waste (SCW) of enrichment of kimberlite ores of the diamond-mining industry (the Lomonosov diamond
mine, Arkhangelsk Oblast) as a binding substance for mineral wool heat insulating materials is analyzed. An express-method for determining the activity of a binder (A) with the help
of the functional dependence of the binder activity on the value of heat effect of the hydration reaction is proposed. The rectilinear functional dependence of А=f(∆H) type obtained has

The perspectivity of processing of wood containing the heart rot in building materials is substantiated. The subject of the study is methods for processing of wood with heart rot. The
shortage of hardwood and softwood demands to treat the unmerchantable wood. Most often, wood with heart rot is sawn for firewood and sold the population as fuel. Differentiated
approach to the choice of the method for processing of wood with heart rot is the substantiation of the type of the obtained materials and products of various functional purposes
depending on the size of heart rot. To ensure the competitiveness, products made of wood with heart rot must have higher performance characteristics in comparison with existing
materials and products. Therefore, the methods of producing need to be connected with specific materials or products. Wood with heart rot of a diameter of up to 50 mm is the most
appropriate to use for the production of rounded logs. For processing of wood with heart rot of diameter of 50–100 mm, the best method is a rotary cut of healthy wood for subsequent
bonding of plywood products. From wood with heart rot of a diameter of 50 mm and more, square-edged sawn timber of small sizes (pallets) can be obtained.
Keywords: wood, heart rot, processing, plywood, rounded logs, defects.
