“…New factories are being built, the product range is being expanded, but this happens overwhelmingly due to the supply of imported technological lines of plastic molding, while construction of semi-dry molding plants is rare cases. However, according to the domestic and foreign experience, as well as the technical and economic analysis, compression molding technology has a number of advantages and becomes widespread in Russia and in Western Europe [1][2][3][4].…”

This work presents the results of the laboratory research on the impact of grain size composition of raw mixtures on properties of heat processed products when implementing the compression molding method. We have analyzed opokas of several fields: Zhuravksy, Shevchenkovsky and Bekeshevsky. Grain size composition of ground materials was characterized by a greater grain size of 0,315; 0,63; 1,25 and 2,5 mm. The link between degree of grinding and caking index, water absorption, mean density, compression and bending resistance was established. The conclusions based on the research results revealed the impact of grain size composition on properties of ceramic products and application potential of opokas as a feedstock in the ceramics industry.

“…Mineralogy of argillites is featured by two types of hydra micas: an isometric one being allothigenous constituent and a bladed one being the transformation product of montmorillonite underwent catageneses. Also argillites always contain kaolinite, chlorite, glauconite, quartz, plagioclase [5,6].…”

The article provides an overview of the argillites raw material of Russia. It describes chemical and mineralogical characteristics of argillites and their main properties. It indicates that argillites chemistry has some peculiarities like high content of A2O3 – from 17 to 23 %, К2О – from 2,5 to 4,3 % and iron oxides from 4 to 7 %. Mineralogy of argillites includes two types of hydra micas: an isometric one being allothigenous constituent and a bladed one being the transformation product of montmorillonite underwent catageneses. Also argillites always contain kaolinite, chlorite, glauconite, quartz, plagioclase. The article contains the main requirements for paving clinker and ceramic tile and major trends of their production. Information about dependence of the effect of argillites reduction ratio and firing temperature on strength, absorption capacity and density of the samples is provided. Influence of their interconnected nature on the properties of the product is described. It is specified that due to finer argillites reduction in the size range of 0-0.16 – 0-1.25 mm, the samples strength increases 1.5-2.5 times. Higher firing temperature in the range from 900 to 1100 °C allows increasing strength 2-4 times. In given intervals of reduction ratio and firing temperature the index of water absorption capacity of less than 5 % needed for ceramic tile is achieved by size reduction of 0 – 0.315 mm and firing temperature of 1000 °C and higher. The water absorption capacity of less than 2.5 % needed for paving clinker is achieved by size reduction of 0 - 0.315 mm and firing temperature of 1050 °C and higher. Rationale for production perspectiveness of paving clinker and ceramic tile of low-temperature sintering based on argillites is provided.

The energy efficiency concept incorporates energy conservation and durability components involved in the operation of buildings and cost considerations pertaining to the manufacturing and installation of materials. Ceramic brickwork offers the highest reliability and durability category, is not combustible and in terms of these parameters has advantages over other insulated facade cladding systems. Improving the thermophysical properties of masonry made of calcined ceramic products is possible through the use of heat-efficient ceramics and, in particular, porous ceramic stones. It is notable that the use of combustible additives does not enable the uniform distribution of porosity across the material while the high ash content of some additives reduces the quality of the ceramic crock. In this connection, it was decided that the use of exfoliated vermiculite of up to 0.5 mm fraction would be reasonable. A completed experiment made it possible to establish the optimal density of exfoliated vermiculite and a methodology based on the correlation between the properties of ceramic-vermiculite products and consumption of exfoliated vermiculite and ceramic product calcination temperature.
