Facing and Clinker Brick from Siliceous Raw Material of the Shevchenko Deposit Results of the study of possibilities to produce facing and clinker brick from opoka-like raw materials of the Shevchenko deposit by a semi-dry pressing method are presented. It is determined that only when grinding the gaize to less than 0.25 mm followed by granulation of the mass, the physico-mechanical and decorative properties of samples are significantly improved. It is established that the production of these products of red and yellow colour is possible when introducing correcting additives in the mass. A temperature interval for burn- ing of facing products is 1020–1050°C, for clinker products is 1050–1080°C. To produce clinker brick, high-melting clay of the Vladimirskoe deposit is additionally introduced in the mass composition.

Keywords: siliceous raw material, clinker brick, facing ceramic brick, semi-dry pressing, burning temperature.

Prospects of Microwave Sintering of a Alumo-silicate Composition Using Ceramic Technology Results of the study of sintering possibility of an ash-liquid glass composition produced on the basis of ash of the Thermal Power Station-2 of Kazan, consisting of 70% of glass phase and 15% of amorphous phase and ash of the Novo-Irkutsk TPP with 44% 0f crystal phase and 56% of amorphous phase are presented. Ashes consist of hollow vitrified spheres and contain minerals which are part of the burned ceramic material, quartz and mullite first of all. On the basis of samples produced by pressing from the powder on the basis of ash and liquid glass, results of the comparative analysis of strength of samples after heat treatment in the muffle furnace according to the traditional burning in the ceramic technology up to 1000 °C and heat treatment under conditions of microwave heating in the electric field of ultra-high frequency are shown. Samples past irradiation in the ultra-high frequency field have shown greater strength comparing with the sample after conventional thermal heating. The structure of the sintered material and differences in color of the samples of thermal roasting and heating in the UHF furnace are shown. On the basis of the early conducted study of the effect of UHF field on the alumo-silicate compositions taking into account the difference in content of the active amorphous phase part in the ash and differences in strength indicators, it is assumed that the alumo-silicate structure of (share of crystal and amorphous phases) impacts on its reaction ability during the sintering process.

Keywords: ash, liquid glass, UHW field, hollow vitrified spheres, alumo-silicate.

Porous Ceramics on the Basis of Low-Melting Clays and Slurries Results of the study of possibility to obtain porous wall ceramic materials from the masses on the basis of a composition of low-grade clay raw materials and non-plastic components according to the technology of making the initial raw mix porous and subsequent fixation of the porous structure by burning are presented. Compositions of masses ensuring the obtain- ing of necessary porosity and mechanical strength of a ceramic matrix on the basis of low-melting clays and slurries of different origin have been determined. The need to introduce the aluminum powder into the mass composition as an additional pore-forming additive in an amount of 0.1–1.3% depending on the amount of calcium hydroxide in the mixes is revealed. The reasonability to use the broken glass in an amount of 15–20% for accelerating the process of the ceramic matrix sintering has been determined.

Keywords: porous ceramic materials, anthropogenic waste, drilling slurry, water treatment slurry, method of burnable additives.

Wall Ceramic Articles on the Basis of Fine-Disperse Products of Waste Pile Processing The high perspectivity of production of wall ceramic articles on the basis of fine-grained products of processing of waste piles with high content of a coal component is shown. Characteristics of these materials, which factually are the ready ceramic mixture as well as characteristics of articles produced depending on the burning temperature are presented. The interconnection between various properties of articles produced, compression strength limit of which are 10–19 MPa at low density, is established. Recommendations on main techno- logical parameters of the production are made. It is emphasized that the low cost of products are due to the exclusion of expenditures for raw materials related to the development and content of deposits, the practical absence of expenditures for mass preparation, products drying due to the heat extraction from the kiln, the absence of expenditures for fuel required for burning. It is indicated that when producing wall ceramic articles on the basis of fine-grained products of waste piles processing, additional sources of profits related to the reduction in capital and current expenditures for maintenance of waste piles and the use of surplus heat in different directions appear.

Keywords: wall ceramic, anthropogenic raw materials, waste piles, technology.

Experience of Surface Treatment of Ceramic Materials of Construction Purpose The surface characteristics of various ceramic materials using atomic-force and laser microscopes have been investigated. Among various methods of surface treatment glazes were noted. The boundary zone of the glaze and the ceramic shard with the help of scanning electron microscopy have been investigated. The analysis of polymer coatings of bricks, their elemental composition are shown. Due to the heterogeneity of the structure and low hardness the problematic characteristics of polymer coatings are noted. The possibility of control- ling the color of the surface layer of the face brick by changing the burning atmosphere is shown. Positive experience of enterprises on surface processing of brick were noted. The results of magnetron sputter deposition of a thin film of titanium nitride on ceramic materials have been presented. It was suggested that this method should be used for surface treat- ment of building ceramics.

Keywords: ceramics, surface characteristics, glaze, engobe, polymer coating, mineral composition, magnetron sputtering, titanium nitride

Design and Erection of Metal Structures of Large-Span Unique Buildings and Facilities When designing unique facilities, the problems, going beyond current regulations, arise. The development of modern technologies during the last decades, which determined the appearance of new forms, materials, methods of designing and construction, causes new and complex problems. The consequence of novelty and innovations, when changing even main principles of the traditional design and construction, is failures that are caused by single and combined reasons often without precedents. The novelty of technical solutions requires the deep special knowledge, experience in designing of such facilities from an engineer-designer. To provide the quality and high reliability (safety, functionality, and durability) of large-span unique structures, it is necessary to ensure the scientific-technical support of their design and construction, the complex of works of scientific-methodic, expert-control, information-analytical, and organization character with due regard for the use of non-standard design solutions, materials and structures. Examples of the use of modern spatial systems in the construction practice with some recommendations on their design are presented. Issues of ensuring the safety of large-span structures from an avalanche-like (progressive) col- lapse in case of emergency impacts as well issues of the technical monitoring during their erection and operation are outlined.

Keywords: metal structures, unique large-span structures, scientific support of design, progressive collapse, monitoring, unique large-span buildings.

New in Rating of Steel Fiber Concrete and Calculations of Steel Fiber Concrete Structures Principles of the classification and the system of specified strength characteristics of steel fiber concrete proposed in a draft code of rules “Steel Fiber Concrete Structures. Design Rules” are outlined. Main differences in the methods for calculation of steel fiber concrete structures outlined in the draft code of rules from the provisions of the existing SP 52-104–2006 “Steel Fiber Concrete Structures” are considered. The scheme of the bending test of a steel fiber concrete beam-sample is shown. Diagrams of the deformation of steel fiber concrete in the course of compression and tension, the scheme of forces and the plot of stresses in the section normal to the longitudinal axis of a bended steel fiber concrete ele- ment of rectangular cross-section when calculating its strength with reinforcement and without reinforcement are presented. The attention is focused on the fact that when determining the curvatures under short-term loading, the diagrams of short-time deformation of compressed and tension steel fiber concrete are used for calculation; when determining the curva- tures under long-term loading, the diagrams of long-lasting deformation of steel fiber concrete with calculated characteristics for limit states of the second group are used.

Keywords: steel fiber concrete, strength, limit force method, non-linear deformation model, fiber concrete structures, bending elements strength, tensile and compressed zones, rod reinforcement, calculation methods.

Calculation of Dimensions of Self-Stressing Concrete Inserts When Constructing Jointless Reinforced Concrete Structures of Great Length

When erecting the structures of great length made of Portland cement concrete, temperature-shrinkage joints are executed. The large number of joints in structures over 100 m is not technological when foundation slabs of ceiling floors are used in such facilities as warehouses, shopping centers, hotel complexes. That’s why the technology of erection of jointless structures of large length has been developed. The whole surface is divided into hooks and inserts. Hooks are strips of 30–50 m width and inserts are made of self-stressing concrete. After stabilization of shrinkage deformations of conventional concrete, inserts are concreted. When inserts are enlarging, the elastic compression of hooks concrete takes place that pro- vides the seamlessness and crack resistance of the structure as a whole. The magnitude of shrinkage and enlargement deformations depends on many technological and structural fac- tors. Methods for calculation of the required size of inserts with due regard for these factors impact has been developed.

Keywords: concrete, shrinkage, reinforcing, temperature-shrinkage joints, deformation, jointless reinforced concrete structures, stabilization of shrinkage deformations.

Improving the Efficiency of the Use of Composite Glass Plastic Fiber in Concretes Results of the research in improving the properties of fiber concretes disperse reinforced with composite glass plastic fiber are presented. Improving the efficiency of glass plastic fiber is reached due to the modification of a concrete matrix with an expanding additive up to 15% and water soluble resin up to 2% of the cement mass. The efficiency of additives introduc- tion is assessed according to values of the extraction load of some fibers from the concrete matrix; these values are determined according to the specially developed methods. The interrelation between numerical values of loads of fiber extraction and strength characteristics of fiber concrete has been established. It is determined that the maximum load in the course of extraction of composite glass plastic fiber is increased by 75% when the cement matrix is modified with the expansion agent RD and water soluble resin DEG-1 that leads to improving the tensile strength, when the fiber concrete is bended, by 31.1%.

Keywords: composite glass plastic fiber, extraction load, concrete, expansion agent, water soluble epoxy resin.

Assessment of Flame Ability to Spread on the Surface of Paint-and-Lacquer Coating Methods for assessing the flame spread on the surface of paint-and lacquer coatings (PLC) relating to construction materials according to domestic normative documents and foreign standards are considered. Experimental assessment studies of a flammability group, flame spread index and linear speed of flame propagation (LSFP) on the surface of various types of PLC used as finishing and protective coatings in buildings and structures have been conducted. An analysis of test results has been made, dependences of fire danger indicators on the composition and thickness of coatings have been established, the most fire dangerous composite PLC used for finishing of premises of buildings and structures have been revealed. The necessity to determine LSFP for conducting calculations of fire development dynamics in premises of buildings and structures as well as for the calculation of forces and means for fire distinguishing is shown.
