Rational Methods for Raw Material Preparation in the Wall Ceramics Technology of Compression Molding*
The rational methods for raw material preparation in the wall ceramics technology of compression molding are formulated. It is established that for the low-quality clay raw materials and industrial waste the grinding up to class -0.3 +0 mm is required. The best packaging of the fine-dispersed raw material during the molding is achieved through its preliminary aggregation in the mixer-granulators of intense action. It is found that at optimal molding pressures in the process of adobe compaction before the plastic deformation of granules at their boundaries the concentration of the liquid phase takes place due to the squeezing moisture out of the granules that contributes to sintering of the product during burning. In the industrial conditions the possibility for production of an effective facing ceramic brick by compression molding from low-quality raw material and industrial wastes with an optimal stricture, high mechanical and decorative qualities is confirmed.

Keywords: rational raw material preparation, ceramic brick, compression molding, granulation, optimal structure

Energy Efficient Technologies of Ceramic Products Burning in Chamber Kilns
Technical solutions, which make it possible to manufacture chamber kilns of periodical action for ceramic products burning meeting the complex of technological and energy-environmental requirements, are considered. It is shown that the manufacture of chamber kilns for small enterprises which produce from 5 to 15 million pieces of equivalent brick per year and especially use the method of compression molding is very actual one. It is possible to execute the reducing firing in gas-tight chamber kilns. The design of the chamber kiln with recirculation contours makes it possible, with the use of high-speed recuperative burners, to obtain the high uniformity of the temperature field on the surface of heated products and for the whole volume of kiln space as well as to reduce the fuel consumption by up to 40%.

Optimization of Tunnel Kilns
Optimization of brick burning in tunnel kilns by means of organizing the zones of heat carrier recirculation with the use of flame blower of a new type is proposed. Overheating of the ventilator shaft and motor is provided by the simple and reliable clutch. The design of clutch has spokes made in the form of blades which rotate in surrounding air and are cooled by it. Introduction of this method can increase the productivity of the kiln by up to 10% or improve the quality of ready-made products.

Capabilities of Façade Clinker Brick of «LSR» Brand to Substitute Import
The development of production of clinker products in Russia is analyzed. It is shown that after reaching the design capacity by the clinker line of the Nikolsky brick factory of LRS Group, the confident import substitution of this production type has started. On the example of the Housing Cooperative «ZILART», possibilities to use the clinker ceramics for façade finishing are demonstrated. New structural decisions and new options of masonries are presented.

Keywords: import substitution, energy saving, clinker brick, suspended façade, Nikolsky brick factory, HC «ZILART».

Design of Non-Bearing Three-Layered External Walls with Brick Facing in Civil Buildings with Increased Number of Storeys
On the example of the Moscow climatic region, three types of non-bearing external walls of three-layered design from small piece materials with a brick facing layer, ventilated air gap, efficient heat insulation and variants of the internal later – from cellular concrete blocks (type 1), brick masonry (type 2) and masonry made of ceramic stones of 140 mm height (type 3) to use in frame buildings of 50, 75, and 100 m height are considered. Requirements for calculation and design of three-layered external walls, fulfilling of which makes it possible to ensure the reliability of solutions considered at the stage of project development, are presented. As an example, results of the calculation of fragments of walls with one and two openings located in the pitch of bearing structures of 4.4 and 6 m respectively are also presented. The dependence of the facing layer on the height of the building, length of calculated fragments and conditions of fastening to bearing structures is determined.

Keywords: three-layered external walls, ventilated air gap, reliability and safety, vertical temperature-deformation joint.

Influence of Efflorescence in Masonry on The Destruction of the Polymer Coating
This article discusses the causes of salt appearance on the brick building facades and their influence the destruction of the ceramic bricks polymer coating in the operation of buildings. One of the reasons for the formation of efflorescence is brick’s humidity that occurs when unobstructed exposure of atmospheric moisture on masonry because of violations of construction technology of curtain walls. The absence of air gaps in the masonry, between brickwork and insulation, leads to additional moistening of walls at their operation. Discovered that mechanism of efflorescence is initiated by the mortar components. Infrared spectral analysis showed that the reason of efflorescence is sodium sulfate and calcium carbonate, which is formed from sodium oxide and calcium hydroxide. Thus, in accordance with the technical specifications for mortars sodium oxide content, for example, is limited to 0.6%.

Keywords: efflorescence, ceramic bricks, sodium sulfate, calcium carbonate.

Research in Influence of Powder and Granular Aluminum Gas-Forming Agent on Properties of Cellular Concrete
The phase composition and properties of cellular concrete produced with the use of a powder and granular gas-forming agent on the basis of aluminum powder of RA20–RA60 brands has been studied. The granular aluminum gas-forming agent has a high content of active aluminum, 88-90%. Granules possess a low degree of dusting and delay of gas emission in the first minutes in comparison with a powder gas-forming agent. Cellular concrete, produced with the use of granules of aluminum powder, has elevated, by 6–10%, values of compressive strength.

Keywords: cellular concrete, aluminum powder, granular gas-forming agent.

Theoretical and Experimental Substantiations of Calculation of Forces for Pull-out of Anchors from Gas Concrete
Methods for calculation of forces required to pull-out profiled anchors from gas concrete are presented with theoretical and experimental substantiations. It is theoretically substantiated that the growth of limit value of the force required to pull-out an anchor is close to the directly proportional dependence on the depth of its anchoring. A limit force of anchor pull-out from gas concrete is the total resistance of forces preventing it because the shear stress diagram is close to the rectangular one. Presented formulae of calculation of forces required for anchor pull-out make it possible to calculate the forces of anchor pull-out from gas concrete with due regard for its density grade and cubic strength or the class B of compressive strength, characteristic of their profile (thread). When calculating forces, it is necessary to take into account the destruction of gas concrete under the profile picks in the form of shear or cutoff as well as its compaction by fractured particles of cement-sand stone formed in the process of screwing of the anchor. Forces of anchors pull-out obtained by calculation or experimentally are compared.

Keywords: anchors, gas concrete, force of anchor pull-out, cement-sand stone.

Marble Imitations
Imitations of marble are materials obtained by the modification of air binders (gypsum and lime). The development of technology of modified gypsum and lime is aimed at achieving the final strength of products comparable with natural stone and at improving their water resistance. Domestic developments on the basis of the technology of artificial water resistant «stone» for façade works became the base of new methods. For example, a group of materials on the basis of gypsum has been created – polymer-gypsum finishing materials. These materials are manufactured either by molding or by press technology.

Keywords: marble, structure, decorativeness, carbonic calcium gypsum, artificial marble, lime, gypsum.
