Modification of Materials on the Basis of Cement with Hydrothermal Nano-Silica
The influence of silica nano-particles obtained from hydrothermal solutions concentrated at the Mutnovskoye deposit of the South Kamchatka on the properties of the cement-sand mor-
tar and heavy concrete has been studied. The ultra-sound treatment of the solution was used for more efficient distribution of particles in the liquid volume. It is established that the
nano-silica extracted from the hydrothermal solution in the form of sol and nano-powder actively influences on the density: improves it due to the filling of micro-pores of the cement
stone with additional newgrowths obtained as a result of active interaction of the powder; on the rate of strength gain at early stages of hardening; the ultimate strength when compress-
ing materials on the basis of cement, depending on the mass percent of the nano-additive introduction. The most pronounced effect is observed when introducing this additive paired
with a superplasticizer.
Keywords: hydrothermal solution, nano-modifiers, nano-silica, heavy concrete, ment materials.

Comparative Analysis of Influence of Nanomodification and Micro-Dispersed Reinforcement
on the Process and Parameters of Destruction of High-Strength Lightweight Concrete
The paper presents a comparative analysis of the impact of nanomodification and microdispersed reinforcement technologies on the process and parameters of destruction of high-
strength lightweight concretes with hollow microspheres. It has been established that the introduction of microfiber is the most justified in terms of indicators of physico-mechanical
properties and parameters of acoustic emission. Introduction of polypropylene fiber reduces the defectiveness of the structure of the composite, changes the nature of destruction and
leads to an increase of strength characteristics. The use of hollow microspheres with a nanoscale modifier grafted on the surface also contributes to a change in the nature of the frac-
ture and increases the strength of high-strength lightweight concrete. The effectiveness of this method is determined by a smaller amount of modifier (0.01% by weight) compared to
the amount of microfiber, but is limited by the specific strength of high-strength lightweight concrete to 40 MPa.
Keywords: high-strength lightweight concrete, nanosized modifier, nanomodification, fiber-reinforced concrete, defectiveness, fiber, hollow microspheres.

Silicate Filler Obtained by the Method of Thermolysis of Modified Cement Hydrosilicates
It is revealed that the thermolysis of cement hydrosilicates of tobermorite series modified with sucrose is accompanied by the destruction of tobermorite structures and the formation
of silicate particles with a wide range of sizes. Curves of the distribution of particles in micron, submicron and nano-ranges have been determined by the methods of dynamic light scat-
tering and direct measurement of particle sizes. It is also discovered that the type of particle distribution curve depends on the content of modifying carbohydrate and is of non-mono-
tonic character. This is presumably due to the effect of differently directed factors: enhancement of coagulation effects and growth of defectiveness of tobermorite structures. The ther-
molysis of modified cement hydrosilicates is accompanied by the effect of occlusion of carbohydrate in the silicate matrix and the formation of water-insoluble compounds. This makes
it possible to consider the products of thermolysis of modified hydrosilicates as efficient fillers for cement concretes, including high-strength concretes.
Keywords: modified tobermorite, thermolysis, nano-particles, curves of particle distribution, cement concretes.

Thermal Efficient Foam Concretes of a New Generation for Low-Rise Construction
The analysis and integration of results of the study complex of foam concretes ρ=800–1600 kg/m
of various modifications, system study and evaluation of their functional properties –
thermal-physical, strength and stress-related characteristics – are presented. Efficient ways of the use of foam concrete of various modifications in the structures of thermal efficient
low-rise houses are shown. Characteristics of foam concretes have been established for calculation of design of structures on their basis with due regard for the influence of long-term
processes. The author’s technology “Monopor” based on the use of normally hardening foam concretes with various types of fillers providing the maximum autonomy, mobility of the
low-rise monolithic construction is characterized. The perspectiveness of this technology determined by its flexibility and universality is substantiated as its realization ensures the pos-
sibility of construction of various types of low-rise buildings with the use of the same range of material and equipment set. The efficiency of the use of this technology when construct-
ing low-rise buildings is shown on the basis of the technical-economic assessment.
Keywords: foam concrete, deformability, technology of monolithic low-rise construction.

A Dry Mix for Producing Refractory Foam Concrete
The composition of the dry mix on the basis of a two-component binder (aluminous cement and clay of “Kustikha” deposit), mineral additives (metakaolin, sulfoaluminate modifier
RSAM, waste of basalt fiber), foaming agent Ufapore, and accelerating and plasticizing additive “Citrate-T” has been developed. When mixing the mix with water at the water-solid ratio
of 0.45–0.7, subsequent mechanical blowing out and hardening of foam mass, refractory foam concretes of 300–650 kg/m
density (depending on WATER/AGGREGATE (W/A) ratio,
compression strength of 0.2–2.5 MPa before heat treatment, are formed. These compositions obtain the initial strength due to the processes of hydration hardening of aluminous
cement that provides the formation of porous structure of foam concretes. The final strength of 0.3–3.2 MPA they gain after burning at 1000
C. Due to the processes of solid-phase sin-
tering of clay with other components of the dry mix during the heating up to 1000
C, the strength is improved, unlike foam concretes on the basis of Portland cement and aluminous
cement. Introduction of the accelerating and plasticizing “Citrate-T” to the dry mix leads to improving rheological properties of the foamed mass and reducing the time of its setting and
hardening. The significant role of W/A when producing foam concretes is established: increasing W/A from 0.45 to 0.7 increases the volume of foam mass after blowing out, inhomoge-
neity of pores and their sizes that leads to reducing the density of foam concretes and compression strength.
Keywords: dry mixture, refractory foam concrete, mineral additives, foam former, accelerators, plasticizing additive.

Strength and Deformability of Stone Masonry Made of Cellular Concrete Blocks
of Autoclaved Hardening with Polyurethane Joints. Part 2. Bending Tensile Strength
Results of the experimental study of bending tensile of the samples of stone masonry made of cellular-concrete blocks with thin-layer polyurethane joints are presented. On the basis of
experimental studies, peculiarities of the destruction of experimental samples have been revealed, values of bending tensile strength of stone masonry along bound and unbound sec-
tions have been obtained. The level of anisotropy of bending tensile strength of the masonry with polyurethane joints has been determined. It is established that when the bending
moment acts perpendicular to the plane of the masonry with polyurethane joints, its destruction is due to the exhaustion of tensile strength of block’s material. The comparison of
results obtained with results of the experimental study of the stone masonry made of cellular concrete blocks with thin-layer glue polymer-cement joints has been made. The difference
in the destruction nature of masonry samples on polymer-cement glue solution and adhesive foam as well as their strength characteristics at tensile bending are shown.
Keywords: stone masonry, cellular-concrete blocks, polyurethane glue, ending tensile strength, bound section, unbound section.

Effect of Water-Retaining Admixtures on Some Properties of Self-Compacting Concretes
Part 1. Rheological Characteristics of Cement Compositions
An analysis is made and the development of a single method for assessment of compatibility of superplasticizers and cement according to the rates of bleeding of cement with additives
and critical shear stress of cement suspensions is attempted. It is established that the value of bleeding coefficient of cements with superplasticizers and water-retaining agents is differ-
ent but the character of bleeding is the same. The introduction of water-retaining additives makes it possible to reduce the bleeding of cements. The use of water-retaining and stabiliz-
ing substances leads to increasing the dispersity of a solid phase and the molecular interaction between the particles. This causes the appearance of many contacts between them and
leads to the creation of a spatial structural grid that provides the high water-retaining capacity. Selection of the dosages of superplasticizers and water-retaining agents for a particular
cement can be assigned according to the value of limit shear stresses of cement suspensions. The increase in ultimate shear stresses of cement compositions with a superplasticizes
and water-retaining additive indicates an increase in their water requirement. This factor is necessary to take into account when designing the composition of self-compacting mixes,
especially pumped with the use of concrete pumps.
Keywords: bleeding of cement, superplasticizers, water-retaining additives, rheological compatibility of additives and cement, ultimate shear stresses of cement suspensions.

Composition, Properties, and Microstructure of Modified Self-Compacting Concrete for Water Proofing of Flat Roofs of Buildings
Issues of improving the durability of flat roofs of buildings due to the use of modified self-compacting concrete (SCC) are considered. When modifying SCC, a complex modifier has
been developed and the optimization of the composition of the complex modifier with the help of the three-factor experiment has been made. Physical-mechanical properties of SCC
obtained have been determined. The microstructure and phase composition of the modified cement stone were studied. On the basis of the research conducted, namely X-ray phase
analysis and electronic microscopy, it is concluded that the reduced content of calcium hydroxide in samples with complex modifier is due to adsorption of calcium hydroxide with
high-disperse particles and interaction reaction with meta-kaolin that also contributes to reducing the content of calcium hydroxide in the cement stone. The data obtained make it
possible to speak about high operational characteristics of SCC. When the flow class is P5, the modified SCC is of compression strength B50, high frost resistance (F600), and water-

Principles of Design of Fine Carbonate Concretes with Improved Crack-Resistance
Principles of the creation of efficient fine carbonate concretes with improved crack-resistance with the use of local anthropogenic raw materials –wastes of carbonate rocks crushing
both as a filler of the optimized grain composition and as a fine-disperse mineral additive, as well as the role of joint application of a limestone filler and the superplasticizer in improving
the operational properties of these concretes are considered. The limestone filler and superplasticizer in the composition of a complex additive promote the uniform distribution of the
cement inside the mineral matrix of the concrete that positively influences on the process of concrete hardening and formation of its structure and properties. The complex additive
reduces the capillary porosity of the composite, at that the fine-disperse limestone filler provides reinforcement of the cement matrix at the micro-level. For qualitative assessment of
the concrete crack-resistance, the coefficient of crack-resistance is proposed in a simple and convenient form for analyzing.

Efficiency of Modifiers When Regulating Properties of Concrete Mixes
The use of chemical additives of multifunctional action on the basis of polymers and various salts makes it possible to regulate rheological and technological properties of concrete
mixes due to phenomena of adsorption modification of cement grains and product of its hydration. Two types of complex additives of multifunctional action have been developed on the
basis of a modified product of the coke chemistry. SAS-2 Additive contains 50–60% of an active binder, 20–25% of salts of uncondensed sulphonic acid, and 20–25% of sodium sul-
fate. SAS-3 Additive additionally includes the nitri-lotri-methyl-phosphonic acid. Results show that SAS-2 prolongs the safety of mobility of the concrete mix from an hour up to an hour
and a half, SAS-3 – up to 3 and more hours. It is established that SAS-3 is not very sensitive to the mineralogical composition of cements. Despite of slowdown of the initial structure
formation concrete with SAS-3 intensively increase the strength in later periods of hardening. The stable effect is provided within a wide range of cement content (350–500 kg/m
at different initial mobilities of the concrete mixes.

Innovative Screens for Building Materials Industry
Along with the crushing units, vibrating screens are key process equipment for producing the crushed stone. The quality of the finished product and also the economy of the production
process depend on the perfection of their designs, reliability, and repairability. REC “Mekhanobrtekhnika” develops and produces a wide range of vibrating screens with different
designs of boxes, vibration exciters, and sifting surfaces. A standard series of universal inertial screens of GIS type with circular trajectory of vibration of a screen box with an adjustable
level of accelerations amplitude in the range of 2.5–5g is presented. A vibration exciter of a block type, the use of which makes it possible to choose the optimal technological mode of
the screening process and provide the possibility to efficiently separate the hardly screened and wet materials, is described. An example of the substitution of imported screens with the
screens GIS-54 and GIT-72 at the enterprise “Granit-Kuznechnoye” (“LSR-Base Materials-North-West”), which reliable and efficiently operate several years already, is presented.

About Production of High-Quality Cubiform Crushed Stone
It is shown that the volume of crushed stone consumption as a main component for road construction and production of building structures made of concrete are constantly growing
both in Russia and the whole world. At that, requirements for the quality of products, cost efficiency and sustainability of the production are increased. One of the new requirements for
crushed stone is a minimal content of platelet-shaped and needle-shaped grains. A comparative analysis of technical characteristics of various crushing units and techniques on their
basis for producing the cubiform crushed stone is presented. It is shown that the most efficient units for producing the cubiform crushed stone are cone inertial crushers developed at
Research and Engineering Corporation “Mekhanobrtekhnika”. The scientific basis of vibration crushing technique is revealed. Examples of the successful operation of the cone inertial
crushers and vibrating screens at the enterprises of Kazakhstan, where two-stage and one-stage crushing schemes were realized, are presented.

Influence of Activation Methods on Properties of Composite Binding Materials
The influence of activation methods on the properties of composite binders with the addition of basalt has been studied. It is established that the mechanical mixing of components
doesn’t contribute to obtaining the cement stone with high strength properties. When the raw charge is mechanically activated, the high developed chemically active surface of the treat-
ed material is formed and the process of its hydration is accelerated. Physical-mechanical characteristics of materials obtained reach the highest values. The samples of binders
mechanically activated during 15 minutes and containing 30% of basalt have the best indexes. The process of hydro-mechanical activation depends on the amount of the liquid phase
and content of the additive, optimum values of which are 30% and 20% respectively. Ultrasound treatment of the raw charge leads to the instability of the formed spatial structure of
the binder. It is confirmed by the low hydration activity and, consequently, low strength values.

An Aluminum-Silicate Binder on the Basis of Saponite-Containing Waste of Diamond Industry
Results of the experimental study of products of the hydration reaction of saponite-containing wastes separated from the circulating water suspension of the kimberlit ore enrichment
process are presented. Preliminary the saponite-containing material was subjected to mechanical activation till the specific surface of over 35000 m

established by the methods of IR-spectroscopy and scanning electronic microscopy that sub-microcrystals of hydrosilicates of tobermorite group are present in the experimental sam-
ples of the binder with a mineral additive of high-disperse saponite-containing material. It is proved that the mechanical activated saponite-containing material is able to form hydrosili-
cates of additional generation in the process of concrete hardening. The data obtained make it possible to consider the saponite-containing material not only as a sorbent optimizing the
structure formation by means of sorption of the water phase in the process of concrete hardening but also as an active mineral component in binder compositions of a hydration type of

The introduction of fibers and threads into the composition of composite asphalt concrete mixes is a method for improving the stability of asphalt concrete to external loads according
to domestic and foreign sources. The introduction of long length elements – threads, fibers or wire – at fulfillment and consistency of quality indicators as well the convenience of its
use is an insolvable problem at present. The introduction of small size (discrete) elements makes it possible to achieve their uniform distribution (dispersion) in the mixture and to
obtain a “composite” material with higher physical-mechanical properties in the finished structural element. In the course of work, experimental compositions of composite disperse-
reinforced asphalt concrete mixes were selected, the influence of the method of introducing the basalt fiber into the mix on their properties was determined; experiments on fine-tuning
of conditions of preparation and introduction of the fiber into composite asphalt concrete compositions were conducted. The study conducted makes it possible to determine the effi-
ciency of the method for introducing the preliminary prepared basalt fiber into the asphalt concrete mix for improving indicators of physical-mechanical properties of asphalt concrete in
pavements of highways.
Keywords: composite material, technology of production of disperse-reinforced asphalt concrete mixes, basalt fiber, waste basalt fiber, fibers.

Analysis of Efficiency of Two-Layer and One-Layer Heat Insulation of Ventilated Facades
Two variants of the heat insulation of one of the most efficient solutions of heat insulation of an enclosing structure, suspended ventilated facades, are compared. Two variants of the
arrangement of a heat insulation contour, a mono-layer, when the heat losses through the junction joints of heat insulation slabs are unavoidable, and a two-layer where the upper layer
of slabs overlaps the junction place of the lower layer slabs, are considered. The calculation method with the use of the specialized software HEAT 3D shows, on the example of an
objects located in the city of Novosibirsk, that from the point of view of heat insulation of buildings, the two-layer heat insulation of ventilated facades is more efficient than the one-lay-
er as makes it possible to improve the thermal-technical homogeneity by 37% and reduce the heat losses through the slab joints by 10 times.
Keywords: energy saving, heat insulation, suspended ventilated facade, energy efficient solution, thermal-technical homogeneity.
