Characterization of waste clay from the sardes (salihli) placer gold mine and its utilization in floor-tile manufacture (pdf download available)


The aim of this work was to evaluate the use of Sardes waste clay (SC) from the Pomza Export placer gold mine at Sardes (Salihli), Turkey, as secondary raw materials in ceramic floor tiles. Stock market future predictions 2015 To obtain consistent quality, we monitored the physical and chemical properties of SC and fabrication conditions. Rmb to usd Once SC was demonstrated to be acceptable as a secondary raw material, laboratory and industrial tests were conducted to understand the reaction mechanisms during firing and to determine the chemical, mineralogical, and technical properties of the reagents and products.

Euro usd chart The mineralogical composition of SC is dominated by quartz, plagioclase, K-feldspar, hematite, calcite, and clay minerals (muscovite–illite, chlorite, kaolinite, and smectite).

Euro usd rate We compared the chemical compositions of the waste clay with those of other red-firing Aegean clays. Silver price chart 5 year The physical properties (water absorption and contraction) of SC were assessed after firing separately at temperatures of 950, 1000, 1050, 1100, and 1150 °C. Usd to ringgit malaysia Ceramic characteristics were determined from pressed bodies, using four elevated firing temperatures (1140, 1160, 1180, and 1200 °C) for samples with 5, 10, 15, and 20 wt.% SC additions to a commercial floor-tile batch. British pound exchange rate history We also assessed the physical properties of the fired and the unfired tiles, including water absorption, drying and fired shrinkage, and bending strength. Stock market definitions glossary Based on the technological characteristics of the resulting ceramic material, the batch with 10 wt.% SC addition was the most promising composition.

• “In this respect, it is so important that fly ashes and contribute to economy by being recycled in sectors such as; chemistry, ceramic, glass, construction, instead of storing on plant grounds [3][4][5][6][7][8][9][10][11][12]. Futures and options trading meaning The utilization of the different type of wastes in brick tile, and ceramic wastes in the different industries has been investigated as: waste-brick [13], granite wastes [14], coal fly ash [15], borax waste and dewatering sieve borax waste [15, 16], ceramic roof tile [17], waste clay from gold mine [18], gneiss rock waste [19], ornamental rock-cutting waste [20], muscovite granite waste [21]. Conversion rate aud to usd Reusing of tile waste and coal fly ash mixture has gained many features to the roof tile industry as low cost, environmentally friendly and energy efficiency raw material. 1 nzd to usd “

[Show abstract] [Hide abstract] ABSTRACT: Some of the rocks and soil-originated materials used in building construction are the serious natural radiation sources. Dollar and rupee exchange rate Soil-originated bricks and roof-tiles and their raw material in the Salihli-Turgutlu area were tested in situ for natural radiation levels using a gamma-ray spectrometer. Secret messages in logos The concentrations of the radioelements 40K, 238U and 232Th and air-absorbed radiation rates were measured for soil, raw material heaps, brick and roof-tile stacks and waste brick heaps. Rub usd The radium-equivalent activity Raeq of the raw material varied between 187.9 and 216.4 Bq kg−1. Usd to chf exchange rate The external radiation hazard index Hex values ranged between 0.51 and 0.58. Gender articles For building material and its products, recommended Raeq and Hex levels are 370 Bq kg-1 and 1.0, respectively. Currency converter usd to aed On the other hand, both Raeq and Hex values for waste brick heaps, containing broken brick pieces, coal pieces and ash, were higher than the recommended levels, i.e. Usd to aud rate Raeq values varied from 473.8 to 651.0 Bq kg-1 and Hex values were within the range 1.15–1.76. Futures market news The annual dose rate and radium-equivalent activity values of the brick and roof-tiles were below the level of criteria. Convert to binary code Annual dose rate ranged between 0.42 and 0.62 mSv y−1 and radium equivalent activity was in the range 172.9–245.2 Bq kg−1. Usd to inr forecast 2015 The external and internal radiation hazard indices were all below the value of 1.0 for the Salihli-Turgutlu area bricks and roof-tiles. Us stock futures cnn money Results of this study were compared with results of previous studies. 1 rmb to usd Natural radiation levels of construction raw material of study area are generally higher than of those of previous studies.

Today’s exchange rate usd to cad This work proposes the mixing of textile laundry wastewater sludge with clay in order to produce bricks for civil construction. Binary to text converter online The applied sludge and clay were previously characterized in terms of their composition, microstructure and thermal behavior. Euro to dollar exchange rate 2015 Ceramic bricks were fabricated with different quantities of textile laundry sludge and they were evaluated in terms of their mechanical characteristics, besides environmental issues verified through leaching and solubilization tests. Love quotes for girlfriend The obtained results showed that sludge can be incorporate until a concentration of 20% (mass basis) producing suitable bricks in terms of its mechanical properties. Chf usd bloomberg Besides, the produced brick are safe and inert according to the applied leaching and solubilization tests.
