Earthen construction represents almost 30% of the housing in developing countries, partially because its low cost compared to steel and concrete construction, also raw materials are available everywhere. One biggest disadvantages earthen is lack information variety on their constitutive materials, specifically soil type. This work addresses physical mechanical properties adobe matrices containi...
In this investigation, the use of phosphotungstic acid (PWA) and phosphomolybdic (PMA) as well Zn2+ containing kaolin bentonite explored for chemical recycling post-consumer poly(ethyleneterephthalate) (PET) wastes have been explored. The clay supported catalysts 5wt% metals heteropolyacids (HPAs) synthesized using wet impregnation method. Nitrogen adsorption desorption studies, SEM–EDX mapping...
The current production of zeolites from natural sources requires high temperatures to achieve a phase change in the feedstock materials. Thermal processes such as calcination are energy-consuming and industry relies on fossil fuels generate necessary heat, which is neither sustainable nor environmental. This study presents for first time treatment aluminosilicate clay kaolin solar reactor produ...
Roadway performance can be improved through utilizing modified bitumens and/or bituminous mixtures within the structure. Regarding this view, Kaolin-containing-Organic Additive Material (K-c-OAM) has been synthesized chemically in study. K-c-OAM is a new additive material obtained laboratory conditions with reaction of kaolin, kind clay, and ethylene glycol. 50/70 penetration grade neat bitumen...
Sheykh Abad area is located in South Khorasan Province, about 90 km south-west of Birjand. The geographical coordinates of area is 59° 00¢ 50² to 59° 06¢ 20² longitude E and 32° 26¢ 20² to 32° 29¢ 32² latitude N. The study area is located in geotectonic Lut Block zone. Eocene sub-volcanic units are altered by hydrothermal solotions in Skeykh Abad area. Kaolinite, Montmorillonite and quartz are ...
A bioflocculant-producing bacteria, isolated from sediment samples of a marine environment in the Eastern Cape Province of South Africa demonstrated a flocculating activity above 60% for kaolin clay suspension. Analysis of the 16S ribosomal deoxyribonucleic acid (rDNA) nucleotide sequence of the isolate in the GenBank database showed 99% similarity to Bacillus toyonensis strain BCT-7112 and it ...
-Intercalation complexes of a Hungarian kaolinite were prepared with hydrazine and potassium acetate. The thermal behavior and decomposition of the kaolinite-potassium acetate complex was studied by simultaneous TA-EGA, XRD, and FTIR methods. The intercalation complex is stable up to 300"C, and decomposition takes place in two stages after melting of potassium acetate intercalated in the interl...
