In this study, the physical and chemical properties of colemanite ore waste from concentrator, coal bottom ash, fly ash, cement+ash mixtures, cement+colemanite ore waste, and their effects on the mechanical properties of ...
This study has examined the effect of natural pozzolan (NP), colemanite ore waste (CW), coal fly ash (FA), and coal bottom ash (BA) on the properties of cement and concrete. The parameters studied included compressive ...
The possibility of using tineal ore waste (TW), coal bottom ash (BA), and fly ash (FA) as partial replacement in concrete was examined through a number of tests. The properties examined include setting time, compressive ...

The heavy metal pollution of Lake Sapanca located in the Marmara region (Turkey), was investigated over time. The lake is the drinking water source of the city of Adapazari and its environs. The D-80 (TEM) motorway passes ...
The effect of bentonite, colemanite ore waste (CW), coal fly ash (FA) and coal bottom ash (BA) on the properties of cement and concrete has been investigated through a number of tests. The properties examined include setting ...
The potential and limits of rice husk to prepare relatively pure activated silica were investigated. For the activated silica, rice husk samples were submitted to a chemical pre-and post-treatment using HCl, H2SO4 and NaOH ...
Red mud (bauxite waste) emerge as by-product from the caustic leaching of bauxites to produce alumina and it causes serious problems such as storing and environmental pollution. In this study, red mud, which is the industrial ...
Activated carbons' were prepared by ZnCl2/CO2 and other salt solutions/CO2 activation of the rice husk. The products were characterized in terms of density, elemental analysis, specific surface area, and porosity. The ...
In this study, the general purpose Finite Element Code, ABAQUS, with a non-linear solution has been employed to study the neck profile in drawn polymers. Attempts are made to obtain the relationship between the neck profile, ...

In this study, a new surfactant-solvent system was described for the preparation of periodic stripe patterns of zeolite A on solid substrates. The evaporation induced self-assembly of zeolite A particles was due to the ...
The aim of this study is producing the low-cost activated carbon rice husks by chemical activation using zinc chloride (ZnCl2) at 700 degrees C in N-2 atmosphere. Impregnation ratios of 1:1 2:1 3:1 and 4:1 (g ZnCl2/g rice ...
