Much industrial waste has mineralogical, chemical and physical characteristics similar to clays used in ceramic materials, enabling the reuse of these as raw materials in the ceramic industry. The ashes are a type of waste containing metals, which can cause air pollution, responsible for serious respiratory problems in the affected population. This study investigate the use of waste derived from the carbonization of a solid fuel (wood) in ceramic paste used for the manufacture of rustic floors, aiming its incorporation into the mix, partially replacing (lessening the environmental problem) the usage of raw material (saving clay), enabling the analysis of certain variables of sample preparation (characterization and formulation) and their influence on the final properties of the material. Results indicate that the partial replacement of clay by ash is feasible in the chemical and mineralogical aspects in the formulation of ceramic paste in the manufacturing of rustic floors.

The sugarcane industry generates huge amounts of sugarcane bagasse ashes (SCBA). This work investigates the incorporation of a SCBA waste as an alternative raw material into a clay body, replacing natural clay material by up to 20 wt.%. Clay ceramic pieces were produced by uniaxial pressing and fired at temperatures varying from 700 to 1100 ºC. The technological properties of the clay ceramic pieces (linear shrinkage, apparent density, water absorption, and tensile strength) as function of the firing temperature and waste addition are investigated. The phase evolution during firing was followed by X-ray diffraction. The results showed that the SCBA waste could be incorporated into red ceramics (bricks and roofing tiles) in partial replacement for natural clay material. These results confirm the feasibility of valorisation of SCBA waste to produce red ceramic. This use of SCBA can also contribute greatly to reducing the environmental problems of the sugarcane industry, and also save the sources of natural raw materials used in the ceramic industry.

The article deals with the manufacture of modern structural ceramic materials from clay and loam deposits of the Republic of Sakha (Yakutia). The importance and relevance of the development of the production of building materials from local raw materials is emphasized, since this will certainly affect the effectiveness of the construction complex as a whole. The successful development of the construction complex is capable of not only stimulating growth in all sectors of the economy, but also contributes to solving the most pressing social problems. Today, Yakutia has huge reserves of mineral raw materials for the production of a wide range of building materials and products. Of practical interest are wall materials made from clay soils. Given the features of the region’s raw material base, this work focuses on additional processing of traditional material. Controlling the complex physicochemical and structural-mechanical transformations that occur during heat treatment, a methodology has been developed for creating a composite material that will allow competitive innovative materials with enhanced strength properties to be produced with a reinforcing element with a glassy phase matrix of mullite crystals. The fabricated samples have a wide range of physical and mechanical properties and allow using it as a high-quality structural building ceramics, as well as industrial floor technical tile.

Red mud is the main solid residue generated during the production of alumina by means of the Bayer process. In order to expand the comprehensive utilization field of red mud and develop new ceramic products with low radioactivity utilizing red mud, the exploration of preparing self-releasing glaze ceramic materials using red mud as raw material was carried out. During the exploration, the self-releasing glaze ceramic materials with low radiation level were produced by normal pressure sintering process using the main ingredients of red mud, red sandstone, barium carbonate and ball clay. The properties of the self-releasing glaze ceramic samples were investigated by the measurements of mechanical properties, X-ray diffraction (XRD), scanning electron microscopy (SEM) and radiation measurement. The results show that the self-releasing glaze ceramic materials have good mechanical properties (the bulk density, 3.10 g/cm3; the compressive strength, 78.00 MPa). Adding barium carbonate to the raw materials and then calcine them to ceramics, which can extend the sintering temperature range and the radioactivity level of the self-releasing glaze ceramic materials can be reduced to that of the natural radioactive background of Guilin Area, Karst landform (the average 60 Total/Timer).

research by some scientists shows that the most expensive element in the manufacture of construction ceramics are clay materials, in particular kaolins. They allow getting products with high strength, but at the same time increase significantly the mass refractoriness. In this connection, a significant amount of melt is added or the firing temperature is increased. Of course, this leads to an increase in the cost of products. In Russia, the reserves of these raw materials are insufficient and it is advisable to look for new non-traditional types of raw materials. There is a need to adjust the component composition of ceramic masses and use non-plastic raw materials. An example is natural wollastonites or their analogues in the form of diopside, which are a little-used type of mineral raw material. In the Siberian region, there are several deposits of non-plastic varieties of raw materials for the production of fired construction products. The most famous are the deposits of the Slyudyansky and Sayan districts. The authors present the results of analysis of diopside rocks, where the chemical, mineral compositions and behavior of samples under heating are studied. The absence of alkali and alkaline earth metal oxides in diopsides was determined. The content of iron oxide in the amount of 0.1% indicates the purity of the raw material. More than half of the composition is occupied by silica, which is 53% and 58% in the rocks of the Burutuysky and Sayan deposits, respectively. The basis of the mineral composition of the samples is diopside, with the presence of quartz, calcite, mica and magnesium carbonate. This range of minerals is traditional in many charges of ceramic materials. Therefore, the possibility of using diopside rocks in the production of building ceramic materials is quite high.

The article considers the use of Jerusalem artichoke processing products in technology flour yeast products. In terms of productivity, Jerusalem artichokes significantly exceed potatoes, sugar beets, corn and other crops of intensive type, but grow it on small area mainly for fodder purposes. Recently, in the food industry is observed reorientation to the production of products with new qualities, aimed at improving the situation health and disease prevention. Jerusalem artichoke is a unique raw material that can increase the biological value of finished products. Useful properties of Jerusalem artichoke are used to strengthen the immune system, reduce the risk of heart attack and stroke, eliminate salt deposits in the joints, in the therapeutic diet for diabetes. However, its limited use in the processing industry is due to the rapid enzymatic darkening of Jerusalem artichoke tubers during processing. Given the specific properties of Jerusalem artichoke, it is advisable to investigate the enzymatic darkening of Jerusalem artichoke tubers during processing by determining the activity of the enzyme polyphenol oxidase and the use of Jerusalem artichoke puree in the technology of yeast dough. Analysis of tubers and Jerusalem artichoke puree was performed by organoleptic and physicochemical indicators. The quality of finished products was controlled by organoleptic, physicochemical and structural and mechanical indicators, among which special attention was paid to indicators acidity, humidity, porosity, shape stability. The activity of the enzyme in whole and crushed Jerusalem artichoke tubers and its effect on the activity of the enzyme pre-blanching in water for 10 minutes It is determined that when blanching is a partial inactivation of the enzyme polyphenol oxidase, which prevents darkening of raw materials during grinding. The effect of adding Jerusalem artichoke puree in the amount of 10, 15 and 20 % was studied on gluten of wheat flour. The partial replacement of wheat flour in mashed Jerusalem artichoke leads not only to a decrease in the amount of gluten, but also to a change in its quality. The gluten becomes more elastic, the extensibility decreases, and with the addition of 20 % puree gluten is torn. It is determined that the duration of fermentation of dough samples varies depending on the amount introduced Jerusalem artichoke puree. With increasing percentage of Jerusalem artichoke puree in the dough recipe, the duration of dough fermentation is reduced by 6.25…8.75 %. The addition of puree had a positive effect Jerusalem artichoke to increase the yield of the finished product by 5.20…26.34 %. Research of the main quality indicators of experimental samples confirm that according to the set of indicators, the optimal sample is 10 % of Jerusalem artichoke puree, which makes it possible to recommend it for the production of yeast bakery products of high biological value.
