The results of laboratory studies to determine the suitability of clay raw materials of the Klyuchevsky Sandstone field for the production of ceramic bricks by plastic molding are presented. It is established that the introduction of the composition of the batch of associated lithoidal rocks as emaciated additives, coal and kaolinite-hydrologist Vladimirovskaya raw material fields, as well as adding the modifying additives that increase frost resistance, it is possible to obtain ceramic samples that meet the requirements of GOST.

Due to the depletion of the natural base of non-metallic minerals used for the production of high quality aggregates for concrete, and also because of the significant damage to the environment when working sartirovochnyh crushing plants becomes relevant greater use of fine-grained concrete on local , not always of high-quality materials. Rostov region has large reserves of river small and very fine sand , not suitable for the preparation of concrete mixes. The article suggests ways to improve the quality of fine concrete local fine sands with the introduction of their composition from fine mineral filler (the TMN ), the role of which carry waste production and processing opal - carbonate- kristabolitovyh kremnizemistyh flasks Maslovskoye deposit Rostov region. Chosen route of administration mikronaponitelya and optimal dosage , to analyze the impact of THM on Water-solid, water-cement ratio and the strength of concrete .

Results of researches on joint influence of specific pressure of pressing and firing temperature on physico-mechanical properties of laboratory samples on the basis of atyukhtinsky clay raw materials is shown. For the purpose of increase of frost resistance of the burned samples into structure of masses entered a carbonat containing modifying additive in an amount of 5%. For a quantitative assessment of influence of the specified factors on the main indicators of the burned samples researches with application of mathematical planning of experiment and computer processing of results were conducted. Specific pressure of pressing varied within 20±5 MPa, firing temperature – 1000±50 0C. By results of experiment the regression equations are received. It is defined that at increase of value of both varied factors, frost resistance and durability of samples increase, and water absorption – decreases. It is shown that, operating even with two technology factors – the specific pressure of pressing and firing temperature – it is possible to change significantly properties of finished products, and, using the received equations, it is possible to predict future properties of products at a stage of their production.

  In article are offered results of research of sinter ability clayey silica clay. It is shown that the ceramic shard based on the silica clay have a low average density, increased firing shrinkage, porosity and water absorption. Increasing the firing temperature to a large extent determines the increase in shrinkage and reduced water absorption. At least increase the density. The data presented in the paper can be a useful technology of brick factories, employees testing laboratories and design companies, geologists studying nonmetallic raw materials, as well as undergraduate and graduate students specializing in this field.

  The paper presents the results of a study of powdered ceramic materials based on silica clay the production of bricks method of compression molding. It is shown that the press powders based on silica clay pressed in a wide range of moisture content, the maximum compatibility in terms of the solid phase is achieved at a certain humidity in the range of 15–30 MPa compaction pressure (depending on the type of molding boxes and humidity), the density of compacts in terms of solid phase begins to exceed the average density of the material (density in the piece), for pressing molding powders with a moisture content below the optimum, almost regardless of the specific pressure extrusion, different-density compaction can reach 4–6%.

  In article are offered the main problems arising at release of a figured brick are shown and versions of their decision. Prospects of production of a figured ceramic brick on the basis of siliceous breeds – silica clay the description of technological decisions is given by production of products by way of compression formation. Offered classification of a figured brick by a form and appointment, and also design of the most demanded forms of an obverse brick is given.
