  • Effects of colemanite waste, cool bottom ash, and fly ash on the properties of cement 
    Sevinç, Vahdettin (PERGAMON-ELSEVIER SCIENCE LTD, 2001)
    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 ...
  • Effects of supplementary cementing materials on the properties of cement and concrete 
    Sevinç, Vahdettin (PERGAMON-ELSEVIER SCIENCE LTD, 2002)
    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 ...
  • Evaporation induced self-assembly of zeolite - A micropatterns due to the stick-slip dynamics of contact line 
    Olgun, Uğursoy; Sevinç, Vahdettin (ELSEVIER SCIENCE SA, 2008)
    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 ...
  • Heavy metal contents of Lake Sapanca 
    Sevinç, Vahdettin; Yalçın, Nevin (SCIENTIFIC TECHNICAL RESEARCH COUNCIL TURKEY, 2001)
    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 ...
  • Influence of natural pozzolan, colemanite ore waste, bottom ash, and fly ash on the properties of Portland cement 
    Sevinç, Vahdettin (PERGAMON-ELSEVIER SCIENCE LTD, 2003)
    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 ...
  • PRODUCTION OF ACTIVATED CARBON FROM RICE HUSK TO SUPPORT Zn2+ IONS 
    Altıntığ, Esra; Acar, İrfan; Altundağ, Hüseyin; Özyıldırım, Ömer (PARLAR SCIENTIFIC PUBLICATIONS (P S P), 2015)
    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 ...
  • Studies of the surface area and porosity of activated carbons prepared from rice husks 
    Sevinç, Vahdettin; Yalçın, Nevin (PERGAMON-ELSEVIER SCIENCE LTD, 2000)
    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 ...
  • Studies on silica obtained from rice husk 
    Sevinç, Vahdettin; Yalçın, Nevin (ELSEVIER SCI LTD, 2001)
    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 ...
  • Utilization of bauxite waste in ceramic glazes 
    Sevinç, Vahdettin; Yalçın, Nevin (ELSEVIER SCI LTD, 2000)
    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 ...
