The simulation test device of filtration for high temperature dusty gas was established based on rotating foam ceramic material. The influence of performance parameter of foam ceramic on collection efficiency, concentration of dust emission, dedusting precision and pressure loss were researched under room temperature condition. The results are shown as following: the smaller the aperture of foam ceramics is, the higher filter efficiency, the overall collection efficiency and filter precision are with lower emission concentration of dust and higher gas pressure loss of dedusting system; about 95% of dust particles which is one twenty-sixth more than the aperture of the filter can be filtered by foam ceramic; increasing the thickness is effective ways to improve the filter efficiency at the expense of much increasing gas filtering resistance of dedusting system; with the increasing of foam ceramic aperture-gradient, gas filtering resistance reduces remarkably at the expense of slight reduction of filter efficiency and a little increase of the concentration of dust emission.

The propagation characteristics of terahertz (THz) waves incident vertically into inhomogeneous and collisional dusty plasma with a ceramic substrate are studied using the scattering matrix method (SMM). The effects of the incident wave frequency and plasma parameters, such as the maximal electron density, dust particle density, dust particle radius and collision frequency, on the reflectance and transmittance of THz waves in the dusty plasma are discussed. In addition, the differences of the propagation properties in the dusty plasma, with and without ceramic substrate, are analyzed. Meanwhile, the differences of the propagation properties in dusty plasma and common plasma, respectively, with ceramic substrate are also compared. Simulation results show that the substrate and dust particles have significant influence on the propagation characteristics of THz wave in plasma sheath. Finally, the transmission increases with the increase of electron density, dust density, dust particle radius and collision frequency.

This research focuses on a study of the strength of concrete with ceramic waste as coarse aggregate and quarry dust as fine aggregate. The sources of ceramic waste and quarry dust are obtained from the industrial in Malaysia. Presently, in ceramics industries the production goes as waste, which is not under going the recycle process yet. In this study an attempt has been made to find the suitability of the ceramic industrial wastes and quarry dust as a possible replacement for conventional crushed stone coarse and fine aggregate. Experiment were carried out to determine the strength of concrete with ceramic waste coarse aggregate and quarry dust fine aggregate to compare them with the conventional concrete made (with crushed stone coarse aggregate). From the results show that compressive strength of concrete with quarry dust as aggregates is the highest with 30.82 MPa with density 2251.85 kg/m3. This show, ceramic waste and quarry dust can be alternative aggregate for comparable properties.

The article indicates the issue of revitalization of urban areas on the example of the former provincial city. Particular attention was paid to threats to the natural environment caused by difficulties in managing construction waste arising during this process. During the research work on waste demolition material from repairs and reconstruction of buildings, ceramic construction waste was selected. These materials were crushed and dust was generated from them. The purpose of the work was to study the activity indicator, i.e. the research that is carried out for dusts obtained, e.g. in metallurgical processes. The parameter described was a determinant of the possibility of using dust as a recyclable cement substitute in concretes and mortars. The research material was ceramic waste. The waste was picked up from the landfill and sorted. Wastes of red ceramics were isolated in the form of damaged bricks, hollow bricks and roof tiles. Dust was produced from such prepared waste. The research methodology was carried out in accordance with the standard PN-EN 450-1:2012. The activity index of crushed ceramic dust after 28 days was 60.9%, after 90 days 72%. Given the slight change in the strength parameters of mortars and special considerations of the necessity of waste utilization, the described ceramic dust recycling is considered as a solution possible to implement in the production of mortars and non-structural concretes. Introduction of the results of these works to market activities may contribute to the reduction of waste deposited on landfills.

The corrosion behavior of glass and glass-ceramics fabricated with silicate glass frit mixed with 50~70 wt% EAF dust in the acidic solution was analyzed by both heavy metal leaching test and microstructural observation. The crystallization temperature, Tc of glassy specimens was around 850 measured by DTA and the heat treatment temperature to crystallize a glassy specimen was selected as 950 / 1 hr. The spinel crystal peaks were found in XRD analysis for the glass containing dust > 60 wt%. For the glass-ceramics, however, the spinel peaks in a specimen containing dust > 50 wt% was found with weak willemite peaks. The glass and glass-ceramic specimens showed the first stage of corroding reaction according to Clark models in acidic solution. The glass-ceramic specimens showed much lower a heavy metal leaching concentration than that of glass specimens in the corrosion test in acidic solution of pH=2.95. Especially, the glass-ceramics containing dust 60 wt% showed a heavy metal leaching concentration of 66 % Pb, 60 % Zn and 98 % Fe lower than that of glass specimens due to crystal phases formed, thermodynamically more stable than a glass network structure. From the leaching test that more Zn ion leached out than Fe ion, the spinel crystal phase [ZnFe2O4] showed better corrosion resistant in the acidic solution than the willemite [Zn2SiO4].

In this paper, the propagation properties of a terahertz (THz) wave in a collisional and inhomogeneous dusty plasma with a ceramic substrate and oblique angle of incidence are studied using the scattering matrix method. The influence of the various corresponding parameters, such as the frequency of the THz wave, angle of incidence, electron density, radius and density of the dust particles, and the collision frequency, on the absorbance and transmittance is calculated. The results of the simulation indicate that an increase in the wave frequency increases the transmittance and decreases the absorbance. Moreover, the absorbance of a THz wave in a dusty plasma with a ceramic substrate increases with an increase in the incident angle, maximum electron density, coefficient of steepness, density and radius of the dust particles, and collision frequency. These results provide an important theoretical basis for the problem of communication blackout between ground and spacecraft.

The blast furnace is one the main systems used in steelmaking plants operating with iron ores. In addition to the production of pig iron and slag, the blast furnace operation also generates a considerable amount of wastes such as dust usually collected in the upwards flowing gas. The dust collecting stage, without separation procedures, produces a sludge, which cannot be recycled inside the plant due to the concentration of undesirable earth alkaline metals as well as zinc. A possible solution for this so-called global blast furnace sludge (GFS) is its incorporation, outside the plant, into clayey ceramic products processed at high temperatures. Therefore, the objective of the present work was to investigate the effect of GFS incorporation, in amounts of 5 and 10 wt%, into kaolinitic clay ceramics fired at 750, 950 and 1050oC. Initially, the GFS was characterized and, after processing, incorporated into ceramics that were then tested for the water absorption, linear shrinkage and flexural strength. It was found significant improvements in the properties for GFS incorporated ceramics fired at 1050oC.

Bypass cement dust was supplied from Alkufa cement factory, which has been used in preparing glass ceramic material. The percentage of bypass cement dust which is included in the overall batch is about 30 wt%. The bypass cement dust composition has been modified by adding other materials like marble, granite, and silica, to prepare glass ceramic material by powder technology. The prepared samples with different ratios ingredients were pressed under a load of 15 tons/cm2 for 90 sec, in a steel mold of 30 mm in diameter, liquid phase sintering is carried out by using High-Temperature Furnace at 100 – 1250 º C and 208/ 240 VAC. Techniques including SEM (Scanning electron microscopy) and XRD (X-ray diffraction) tests were then used to evaluate the produced material. The obtained glass ceramic material have high bulk and apparent density, low apparent porosity , high compression strength and hardness , low electrical and thermal conductivity. The XRD and SEM results showed that glass ceramic materials are formed. The phase transformation has happened and the titanite, wollastonite, diopside, periclase, and silica condense clusters phase are formed, which are the important phases of glass ceramic. Tests show that the sample A5 contains 38% bypass cement dust, 30%granite, and 32% silica , the sample C5 contains 28% bypass, granite 30%, marble 10%, and silica 32% and the sample B4 contains 59% bypass , 25% marble, and 16% silica . Showing properties A5 and C5 which conform to that of glass ceramic properties better than B4. The research is considered a pioneer work in the field of investment of dust of bypass cement for producing glass ceramic materials. It represents an important step and could be the basis for future researches leading to the achievement of glass ceramic production in Iraq.

Annotation:

Electric Arc Furnace (EAF) is commonly used in steel recycling industries. Apart from steel metal product, a waste in the form of dust is also produced and so called EAF dust. The fine particulates mainly contain zinc-iron oxides along with a small amount of heavy metals like chromium and lead, and have been categorized as a toxic waste. Proper treatments can be crucially required in order to recover crude zinc oxide and iron oxide from the dust; however, no practical recycling plants have been now readily operated in Thailand. To reduce its toxicity, EAF dust could be mixed with silica-based materials and vitrified into glass. Therefore, EAF dust can possibly be employed as a ceramic glaze raw material. This work pointed out how to make decorative “oil spot” ceramic glaze by substitution of EAF dust for a conventional iron oxide. The prepared glaze mixtures were applied over the ceramic bodies and fired at 1250 °C in oxidation atmosphere. The as-fired glaze appearances with tiny and silvery crystals floating over dark brown based-glaze were exhibited. Phase content and characteristics of the obtained glaze were analyzed. The roles of zinc oxide to iron oxide ratios on oil spot and crystal generation was concerned. A comparison of oil spot effects due to different iron oxide sources was presented and discussed. Oil spot glaze made from a combination of EAF dust and iron oxide powder was also proposed.

The development of value-added ceramic materials deriving only from industrial by-products is particularly interesting from technological, economic, and environmental point of views. In this work, the synergistic sintering of ternary and binary mixtures of fly ash, steelmaking electric arc furnace dust, and ladle furnace slag for the synthesis of compacted ceramics is reported. The sintered specimens’ microstructure and mineralogical composition were characterized by SEM-EDS and XRD, respectively. Moreover, the shrinkage, apparent density, water absorption, and Vickers microhardness (HV) were investigated at different sintering temperatures and raw material compositions. The characterization of the sintered compacts revealed the successful consolidation of the ceramic microstructures. According to the experimental findings, the ceramics obtained from fly ash/steel dust mixtures exhibited enhanced properties compared to the other mixtures tested. Moreover, the processing temperature affected the final properties of the produced ceramics. Specifically, a 407% HV increase for EAFD and a 2221% increase for the FA-EAFD mixture were recorded, by increasing the sintering temperature from 1050 to 1150°C. Likewise, a 972% shrinkage increase for EAFD and a 577% shrinkage increase for the FA-EAFD mixture were recorded, by increasing the sintering temperature from 1050 to 1150°C. The research results aim at shedding more light on the development of sustainable sintered ceramics from secondary industrial resources towards circular economy.

Ceramic is mainly being used as raw material in the production of building finishes. The production processes of this material generated a great amount of waste and by-product in the form of dust, broken tiles and sludge which will lead to environment pollution. The aim of this study is to investigate the potential utilisation of ceramic dust as alternative raw material in the production of sustainable construction components. Target materials of ceramic dust (CD) and laterite clay (LC) on its own or combination of both were stabilised with Portland cement (PC) and hydrated lime (HL) on its own or combination with ground granulated blast furnace slag (GGBS) by-product from steel industry. A blended binder of GGBS and waste paper sludge ash (WPSA) was also used to develop 100% sustainable stabiliser to stabilise the target materials. Compacted cylindrical specimens of 50 mm Ø and 100 mm height were fabricated at 20% dosage of binders concentration and moist cured for 7, 28, and 60 days before tested for compressive strength and water absorption. The results obtained show that stabilised CD with partial substitution of HL and PC with GGBS as stabilisers gave higher compressive strength and has potential to be used in the production of sustainable construction components. This suggests a solution towards a greener future and sustainable use of environmental friendly construction components.

Metallurgical production associates with such processes as crushing, drying and pneumatic transportation of raw materials, roasting, melting etc., in the process of which hard particles and harmful gaseous components are emitted into atmosphere. At pneumatic transportation of raw materials and sand, their concentration in the atmosphere as a rule exceeds maximum permissible concentrations. Existing facilities of dusty flows cleaning in some cases don’t ensure sanitary norms ГН 2.1.6.3492‒17. Technical solutions proposed to clean gases in a centrifugal filter, a facility of complex gas cleaning – cyclo-filter and two-stage system of high-concentrated gas-dust flows cleaning. Description of the centrifugal filter, cyclo-filter, two-stage facility of gas cleaning design presented. The facility comprises centrifugal filter and ceramic pulse filter. Industrial tests of the centrifugal filter ЦФ2-6-1 under conditions of a system of pneumatic transportation of sand established, that efficiency of gas-dust flows cleaning of sand particles in a six-channel filter can reach 98.65%. Application of two-stage system of gas cleaning comprising centrifugal filter and ceramic pulse filter ФКИ enables to reach residual hard particles concentration at the exit of such a facility of 5 mg/m3, having initial dust level of 127878 mg/m3. Application of such a complex two-stage cleaning facility allows to reach values of 0.1 of maximum permissible concentrations near the source of emissions.

By the use of filtration experiment system with single ceramic tube, cold experiment and numerical simulation was carried out about the dust removal process. The experiment shows that airflow conforms to the linear Darcy law, the pressure drop increases with the increase of filtration velocity and dust load; with the increase of gas pressure, the permeability of porous ceramic decreases. Simulation shows that velocity and pressure drop values increase along the axial height from bottom to top and reach the maximum at the exit. Due to the differences of gas velocity or particle size, the amounts of sedimentary particles are different at the tube wall, larger velocity and smaller size particles trend to be more equispaced when they are trapped on the surface of tube.

The article presents various methods of synthesizing heat-resistant binders based on large-tonnage wastes of the ceramic industry. The use of expanded clay dust in the compositions of heat-resistant concrete on portlandcement allowed to increase their residual strength in the zone of critical temperatures (800-1000 ° C). It was revealed and justifi ed that the use of phosphate binders for synthesizing a binder made it possible to increase the refractoriness of the heat-resistant composition based on expanded clay dust to 1300-1350 с. As the experiments show, claydite dust in its composition contains a clay component, which ensures the plasticity of the ramming mass. It was established that samples of ramming mass on orthophosphoric acid did not require heat treatment and can be immediately removed.

Industrial dust emission is a kind of pollution which might occur due to the green sand mold process in the foundry industry. This material is predominately composed by sand, clay, carbon and metallic oxides. The ceramic industry has already assumed the role of consumer of by-products generated by such industries, mainly by having similarity between the composition of by-products and raw material employed in the ceramic sector. In a preliminary study the dust from exhaustion was define as a thin material with a high content of non-plastic material and the presence of carbon, which can interfere with processing and properties of the final product. This study aims to show the effect of exhaustion powder addition in atomized clay in order to develop ceramic coating. The results of the effect of sintering temperature and the percentage of residue on properties such as apparent density, linear shrinkage, water absorption and open porosity are presented.

The article presents the results of scientific and experimental studies on the creation of ceramic refractory material. Montmorillonite clay (bentonite-like) of the Pogodaevsky deposit and ferro-dust from self-decaying slags of low-carbon ferrochrome of the Aktobe ferroalloy plant were selected as the most effective types of raw materials in terms of their physico-mechanical properties and chemico-mineralogical composition. The composition of ceramic mass in chamotte - ferro dust - binder and rational technological parameters of molding, drying and firing was developed. The basic physical and mechanical properties of the obtained ceramic samples, which have high strength, average density, low linear thermal expansion coefficient and fire shrinkage, are studied. Ceramic samples based on the proposed raw material composition can withstand temperatures up to 1350 С, which is 200-300 С higher than ceramic samples based on clay raw materials. The high strength indices and refractoriness of samples are explained by the fact that in result of heat treatment of the studied ceramic composition, a densely sintered framework with reinforced refractory minerals such as forsterite Mg2 (SiO4) and spinel (MgAl2O4) is formed. The prospects of this research area are associated with the creation of innovative technologies for the production of popular refractory materials, but also with an environmental issue. Processing of technogenic resources of Kazakhstan will not only reduce the consumption of natural resources, but also reduce the human impact on the environment.

The residues generated by the ceramic factories, among the most varied types, represent a large part of the waste produced and the one that comes from the production of red ceramics such as tiles and bricks, reflects in great part of all the constituents of these residues. The use of tailings is becoming an increasingly common practice, often because it does not have a correct final destination and in some places, there is a shortage of natural materials. The present work aims to study the addition of residues of ceramic tiles dust in the characteristics and properties of ecological brick. A literature review on the topic was carried out, in addition to granulometric characterizations, absorption tests, thermal comfort and simple compression. After carrying out the tests, the possibility of using it as a component of the ecological brick and using it in the region of Teresina-PI was studied. The samples produced with tile powder residue showed excellent results, therefore, through this study it was possible to prove that the reuse of these residues is valid for use in civil construction.

The study compared lung function among 322 workers in pottery, ceramic, stone-cutter and stone-grinder factories in the west of the Islamic Republic of Iran. Concentrations of silica particles <2 microm were measured in the ambient air of factories. Forced expiratory volume in 1 second [FEV1] and forced vital capacity [FVC] were significantly lower in stone-grinders compared with pottery, ceramic or stone-cutter workers and a control group. No difference in lung function was found in pottery and stone-cutter workers with less than 20 years occupation compared with controls. The prevalence of respiratory symptoms in stone-grinders was higher than other workers. The concentration of silica particles of stone-grinder factories was 40-110 times higher than in ceramic and potteries factories. More attention is needed to ventilation systems and health care of stone-grinders

Evaluation and Comparison of Respiratory Symptoms and Lung Capacities in Tile and Ceramic Factory Workers of YazdTile workers are exposed to dust particles and are susceptible to multiple pulmonary complications. Problems like asthma, chronic obstructive pulmonary symptoms, and silicosis are more common among them. As there are many tile factories in Yazd, we decided to evaluate the respiratory symptoms and lung capacities in these workers and compare them with controls.This study included 176 tile and ceramic factory workers occupationally exposed to dust and 115 unexposed workers as controls. We recorded the respiratory symptoms using the British Medical Research Council questionnaire and measured lung capacities of the two groups.All study subjects were male, and the two groups were comparable in age and smoking. The exposed group had frequent respiratory symptoms and a significant relationship between them and duration of employment. In addition, lung capacities in ceramic workers with symptoms were lower than in workers without the symptoms.Even though the respiratory symptoms were more frequent in the exposed group than in controls, lung capacities of the two groups were similar.

To recycling the EAF dust as a ceramic raw material, the leaching concentrations of heavy metals (Zn, Pb, Cr, Cd) were analyzed with various pH and mixing ratios for EAF dust-clay bodies. The evaporation amounts of the some heavy metals were evaluated by measuring their total concentrations in the sintered bodies of EAF dust-clay mixtures with various mixing ratio and sintering temperature. TCLP test was conducted for evaluating the chemical stabilities of the heavy metal elements. The heavy metals in EAF dust are 'amphoteric metal' and leached a little at pH10. The leaching concentrations of heavy metal ion were effectively decreased by the formation of PSHP when adding the clay to the EAF dust and controlling the pH of the slurry at 12. Evaporation of heavy metal components were increased with increasing the sintering temperature and the contents of EAF dust. The leaching concentrations of heavy metal components were decreased with increasing the clay content and temperature.
