Improvement of Shaft Counterflow Lime-Burning Kilns
On the basis of the analysis of exploited units operation as well as on the basis of results of many model tests, a new design of chargingdistributing device for round and circular kilns
operating under the pressure has been developed and patented. In comparison with all analogues used now it makes it possible to uniformly distribute the charge according to the size
of a piece of charge in the kiln’s shaft regardless of its diameter. A new design of the company – peripheral tuyeres with the diameter reduced up to 90–125 mm and the weight reduced
up to 50–70 kg – is described. For cooling casings it is provided to use the cooling liquid OZh40 instead of technical water.

Energy-Technological Efficiency of Fine Lime Production
The most rational schemes of the organization of process of carbonate raw burning and lime recycling in cyclone cascading kilns at various compositions and moisture levels of the par
ent stock with due regard for costsaving and quality of finished products and possibility of control over the thermal performance of the unit are analyzed by calculation with the help of
a mathematical model. The choice of the most rational design was made using the method of directional improvement of the thermaltechnological scheme that in the process of lime
burning and recycling for each level of free moisture content made it possible to define the design and thermal behavior of the unit which are optimal according to the criterion of heat
efficiency. Results of the mathematical simulation show that the optimal topology of the operating space of cyclone cascading furnaces is determined by the composition and moisture
content of the carbonate raw. Cyclone cascading kilns are not inferior to shaft kilns for thermal efficiency and technical properties of the lime obtained and at that less demanding to the
quality of raw materials used.

Modernization of Shaft Mixed Feed Kilns for Limestone Burning
Modernization of a shaft mixed feed kiln for limestone burning on the basis of modern methods of limestone burning and kiln designs is considered. Shaft mixed feed kilns for lime
stone burning built in the XX century have a lot of shortcomings in the field of lining, gas tightness, dozing, gas purification, and automation. These shortcomings have been overcome
by modifying the design of the kiln, the use of modern materials and automation. The kiln drawing is attached.

Impact-Centrifugal Mills in Production of Building Lime
It is known that ground quicklime, as a binder, has a number of advantages in comparison with slaked lime. High dispersion of quicklime favours the improvement of technological pro
cesses of building materials and products manufacturing, improvement of the quality of finished products. Favorable criterion of grinding fineness of quicklime is the absence of residue
on the sieve № 02 and a small residue on the sieve № 008 (not more than 4–6%). A comparison of the technicaleconomical characteristics of the ball twochamber mill 1456A and the
impactivecentrifugal mill “TRIBOKINETIKA” is made; schemes of grinding plants with ball and impactcentrifugal mills are given.

Optimization of Production Process of Silicate Brick on the Example of the Factory in the City of Kaluga
OOO “INVESTTECHNOLOGY” is specialized in the manufacture and supply of equipment for silicate brick factories. A new step in the company’s development is the turnkey construc
tion of a production line at Kaluga building materials factory (productivity of 100 mil. conventional bricks per year). In the course of executing this project, the engineers of “INVEST
TECHNOLOGY” Co. are based on the more than 20 year experience in designing silicate brick factories and other technological equipment. As a result, a technological line, main param
eters of which exceed traditional technological schemes designed at present, has been developed. One of the most important advantages of the new technological line is its compact
ness that makes it possible to realize the profound automation with the use of transmission bridges of relatively small overall dimensions; it reduces the price, simplifies the
maintenance and reduces the operating costs.

Role of Technological Factors in Formation of Colour of Silicate Coloured Brick
The conversion of an operating line for production of silicate noncoloured brick for producing coloured brick has its own peculiarities; neglect of them leads to the offgrade brick out
put. The originality of the technological process, workshop layout, the presence of draughts and cold season lead to the loss of color on the surface of the brick. The article contains the
study of reasons for formation of white runs on the brick produced according to the technology of volumetric coloration of a slaked molding mix. The influence of climatic conditions in
workshop premises on the temperature of the molding mix and adobe brick stagebystage and the temperature change during the time are shown. Results of the study and the role of
temperature of colored adobe brick, lime, steam condensate in the autoclave at the first stage of steam curing of colored adobe brick are presented.

Polyvinyl-Acetate Binding Materials Modified with Alkoxysilane
Issues of improving operation characteristics, including moisture resistance, of polyvinylacetate binders due to their modification with organosilicone compounds – alkoxysilanes, tet
raethoxysilane among others are considered. The mechanism of interaction of tetraethoxysilane with a polymer binder is considered; dependences of changing the properties of a
polyvinylacetate binder on the concentration of tetraethoxysilane introduced into the composition are studied. It is shown that the introduction of 20–25% of tetraethoxysilane in the
polyvinylacetate composition significantly improves the adhesion characteristics and moisture resistance of the binding material. Taking into account that tetraethoxysilane is toxic,
research in determining the toxic index of developed polymer materials modified with an organosilicone compound has been conducted. The research shows that developed materials
with 20–25% of tetraethoxysilane in the polyvinylacetate binder have low toxicity.
Keywords: polyvinylacetate binder, tetraethoxysilane modifier, index of toxicity.

Part. 3 Dynamics and kinetics of moisture transfer during moisture condensation and evaporation
Physical and mathematical models of heat transmission in dowel connection wood are presented. The physical model is based on the idea of wood to be a colloidal capillaryporous
body. It was shown that under the changing parameters of the ambient temperature the dowel connection being maintained under (cooling to dewpoint temperature) there occurs con
densation of the condensed moisture by the Shchukarev’s law. The mathematical model is based on the nonstationary differential equation of hydraulic conductivity with boundaryval

New Ideas about Action Mechanism of Superplasticizers Grinded Jointly with Cement or Mineral Rocks
Physicalchemical processes of the impact of superplasticizers (SP) on the dilution of cementwater and other mineralwater suspensions in the course of manufacturing of selfcom
pacting concretes of the new generation are considered. It is shown that the process of plasticization of the suspension from cement and mineral powder jointly milled with dry SP is the
most efficient as significantly reduces the viscosity and yield point. It is established that preadsorption dry putting of SP on the mineral surface of microparticles in the process of
grinding and following mixing the suspension with water fundamentally changes the adsorption mechanism. It makes it possible to formulate a new idea in the adsorption mechanism:
“adsorption of molecules of the adsorbent in the course of its dissolution on the adsorbate surface” unlike conventional classical idea: “adsorption of molecules of the adsorbent from
the solution on the surface of the solid phase”.
