Formation of the Phase Composition of Ceramic Stone with the Use of High-Calcium Drill Cuttings Results of producing the wall ceramic on the basis of the composition of low-melting clay raw materials-loam- and a high calcium component – drill cuttings (СDС) in the amount of 30% are presented. The research conducted made it possible to establish the influence of chemical-mineralogical composition, fineness of raw material grinding on the conversion of initial components in the course of burning and formation of the phase composition of ceramics. It is revealed that the thermal processes, occurring in the ceramic product with different content of CaO and Fe2O3, impact on the mechanism and intensity of the formation of crystal phases, structure and properties of ceramic bricks. At this, the temperature of new formations reduces due to the fact that, when CDC dissociates, CaO, which is actively involved in the crystallization of anorthite- and wollastonite-like phases, is formed. Phase and structural changes described make it possible to produce the ceramic brick on the basis of the calcium-containing additive, drill cuttings, with standard physical and mechanical properties.

Keywords: ceramic brick, decarbonization, crystal phase, drill cuttings, new formations, calcium carbonate..

Prospects of the Use of Siliceous Opoka-Like Rocks for Production of Paving Clinker of Low-Temperature Sintering Results of the study of possibilities to produce the paving clinker on the basis of siliceous opoka-like rocks are presented. The general characteristic of these rocks and their carbonateclayey types is given. It is shown that the introduction of mineralizers in the amount of 1% makes it possible to produce products with water-absorption less than 2.5% at a burning temperature of 1050–1100оC. The products obtained meet the requirements of normative documents and have a yellow or dark-yellow color. It is established that the main technological factors when producing the clinker brick are the burning temperature of products, the degree of grinding of the initial rock and the amount of mineralizing additive. Taking into account the properties of clay-carbonate flasks, the method for producing products can be both as an extrusion and compression. Technical-economic calculations show a high efficiency of investments in the production of road clinker brick on the basis of flasks.

Keywords: paving clinker, opoka, mineralizer, grain composition, burning, strength, water absorption.

Perspective Direction of Development of Building Ceramic Materials From Low-Grade Stock* The necessity of expansion of the raw material base of building ceramic materials through the use of low-plastic loam, opal-cristobalite, other silica-containing rocks and mineral industrial wastes is shown. It is necessary to develop new ways of preparing raw materials and molding products with the use of tripolite, diatomite, loess soils, coal waste, ash, etc. The reasons for the decrease in the flexural strength and frost resistance of semidry molding products are compared with plastic molding. Prospects for the development of construction ceramics technology from low-grade technogenic and natural stock are indicated. Various schemes for the formation of spatially-organized structures of ceramic composite materials are considered. Examples of construction ceramics of a matrix and cellular structure from granulated batch based on slime iron-ore waste and granulated foamglass from siliceous rocks are given. The principles of structural coloration of ceramic matrix composites are presented and examples of decorative construction ceramics of the matrix structure are given.

Keywords: technogenic raw materials, construction ceramic materials, matrix and cellular structure, structural coloration, decorative ceramics.

Relationship of Water Absorption and Water Resistance of a Ceramic Tile from Argillith-Like Clays The results of experiments to determine the relationship between water tightness and water absorption of ceramic tiles obtained because of argillite-like clays, which are widespread in southern Russia, are pre-sented. It is shown that with decreasing water absorption the water permeability of the shard is regularly reduced. It is established that with 5% water absorption, the tile can be considered guaranteed waterproof. This figure does not depend on the thickness of the shingles. It is proved that it is possible to reduce water absorption and increase the ultimate strength due to shingles based on argillite-like clays, due to fin-er grinding of the feedstock or an increase in the firing temperature. The justification is given that the production of a ceramic shard with high strength and low water absorption makes it possible to produce tiles with a smaller thickness and weight, as well as lesser probability of bio-logical corrosion.

Keywords: : tiles, argillite-like clays, strength, water absorption, water tightness, firing, grinding.

Influence of Surfactants on Humid Shrinkage of Concretes

The humid shrinkage is the most important and problematic property of contemporary concretes of modified structure reducing their quality. The article shows that the main component of the modifier of concrete structure – an additive-super-plasticizer stimulates the increase of shrinkage phenomena. Features of the structure and composition of additive-plasticizers used at present are revealed. Four trademarks of additive-super-plasticizers with different compositions and structures of macro-molecules are studied. The influence of selected additive- plasticizers on the processes of early structure formation of cement systems (beginning from the moment of components mixing), on the balance of internal (film splintering and capillary retracting) forces in the system in a wide range of water-cement ratios is studied. Further the influence of these additives on the shrinkage indicators is researched. The results obtained already provide the necessary guidelines for specialists and consumers of these additives.

Keywords: humid shrinkage, early structure formation, cement system, additive-super-plasticizers, concretes.

Concrete Mix Structure and Role of Water in Its Physical-Chemical Transformation in Concrete

The concrete mix structure is considered: the subsystem СаО–SiO2–Н2O, basic and acid adsorption centers by Lewis, interaction of water molecules with them with proton transfer, hydrolysis of non-stoichiometric, unstable silicate minerals and formation of the nano-structure in the concrete mix, consisting of their nano-gels SiO2, Са(ОН)2, interaction of the nanostructure with water with formation of intermediate active particles Н+, ОН–, Н*, ОН* leading to the setting. Intermediate active particles interact with adsorption centers and between themselves. Recombination of water molecules takes place but by the law of preservation, charges on the surface of nano-particles are retained, as a result of which the setting occurs. Oversaturated unstable solid solutions (calcium hydrosilicates) are formed, they are subjected to the spinodal decomposition with the formation of nano-clasters of hydrosilicates very active at the moment of release which leads to hardening. It is shown that setting and hardening is the dimensional and chemical effect of nano-particles, calcium hydrosilicates and other particles leading to setting and hardening. The main and initial condition for realizing these processes is an irreversible exothermic reaction of water decomposition into radicals Н*, ОН*with compensation equal to 25 kJ/mol.

Keywords: concrete structure, concrete mix, water, adsorption, cationic and anionic polyhedrons, hydrolysis of minerals, nano-particles, calcium hydrosilicates.

Granite Crushing Screenings as a Component Factor of Concrete Structure Formation. Part 1. Problem Definition. Identification of Screenings as a Component Factor of Structure Formation

The problem of consideration of stone crushing screenings as a component factor of the formation of macro-, micro-, nano-structures of conglomerate building composites is formulated. On the example of structure formation of traditional and high-tech cement concretes, the substantiation of mechanical, mechanical-chemical and physical-chemical role of fraction differences of granite crushing screenings is made. In this context, data on the genesis of screenings and their structurally significant identification characteristics are presented. In addition, ordinary screening, enriched screening, individual fraction differences separated from the ordinary screening, a dust-like part of screening separated from the hydro-removed pulp by drying are considered. A priory, the projected manifestation of the role of types of screenings in the formation processes of the frame component (grains of macro- and meso-fractions) and the matrix component (grains of macro- nano-fractions of screening and products of concrete hydration) of the concrete structure..

Study on Stability of Water-Based Siloxane Hydrophobic Emulsions*

Stability of emulsion structure has to be considered and well controlled during synthesis of hydrophobic water-based emulsions. Due to its critical impact on covering ability and adhesion of hydrophobic coating to the top layer of concrete surfaces. Therein, emulsion composition design, as well as proportion of selected raw materials, are the parameters responsible for the achievement of high emulsion stability. Theoretical computations of hydrophilic-lipophilic balance (HLB) were completed in this research to evaluate the stability of water-based emulsion with incorporated emulsifying polyvinyl alcohol (PVA) and silicone hydrophobic agents (SHA). Using Davies’ method, which considers calculating a value based on the chemical groups of the molecule, PVA and SHA meet all requirements to produce highly stable emulsions. Griffin’s method is based on calculating values for different regions of the molecule and demonstrates that the highest stability of “oil in water” emulsion can be achieved using low molecular weight PVA (up to 15000). As the molecular weight of PVA increases, the HLB drops, which results in reduction of emulsion stability and lifetime. ξ-potential ranges were calculated for the investigated emulsions, prepared using different approaches. The results showed that the emulsions with ξ-potential range of < –35 mV and > 50 mV have the highest stability of emulsion structure.

Keywords: water-based emulsion, hydrophobicity, adhesion, emulsion stability, hydrophilic-lipophilic balance (HLB), zeta potential, concrete.

2 OOO “TEPOFOL” (88, Moskovskaya Street, Bronnitsy, Moscow Oblast, 140170, Russian Federation) Features of Realization of Insulation Systems under Conditions of the Far North Features of the realization of insulation systems under the extreme climatic conditions, including the conditions of significant negative and freeze-thaw temperatures, high wind speeds etc. are outlined. It is noted that the adaptation of building systems to such conditions of operation imposes special requirements and to heat insulation materials concerning their resistance to mechanical and climatic impacts as well as to the stability of properties for the whole operation period. Results of the study of operational durability of non-cross-linked polyethylene foam, which confirmed the inertness of the material to humidity and temperature impacts within the interval from -60 up to 80оC, made it possible to recommend the products on its base (mats and rolls) as insulation for objects of the Arctic Circle. In particular, the project of insulation of the residential module of the two- link tracked transporter was realized. Tests conducted during the Arctic expedition in 2017 in the Republic of Saha (Yakutia) show that the heat insulation on the basis of non-cross-linked polyethylene foam makes it possible to provide the sustainability of the living module during two months at an ambient temperature of -45оC in strong winds with gusts up to 30 m/s.

Keywords: expanded polyethylene, climatic tests, insulation system, welding of polymers, Arctic expedition.

Heat Protection Properties of Coverings on the Basis of Dry Building Mixes of a New Generation

Reducing the energy resources consumption, including for buildings with a significant time of operation means, first of all, the arrangement of the efficient heat protection of external enclosings. Modern methods for heat insulation of building structures characterized by industrial technology of erection often can’t be used, when conducting capital repairs, for architectural monuments especially. In these cases, the suitable way for improving the energy efficiency of buildings is faсade plastering with compositions of a new generation. The wide choice of dry building mixes on the basis of heat protection fillers presented at the Russian market makes it possible, without changing the exterior finish of buildings under reconstruction to execute the protection of external walls not only from negative effects of weather factors but also from excessive losses of heat in the cold period of the year and overheating in the summer period. The analysis of characteristics of the used energy saving fillers and plasters on their base shows that the compositions which include the granulated foam glass have the best heat insulation properties. The obtained dependence of the heat conductivity factor on the density of the plaster layer makes it possible to assess preliminary the energy saving properties of new mixes when varying quantitative ratios of the components used and their qualities. Possible trends in the creation of plaster coatings with unique properties, appropriate indicators of heat protection and strength characteristics are forecasted.

Keywords: energy saving, heat protection, dry building mixes, granulated foam glass.
