Stabilisation of Engine Oil Contaminated Soil Using Cement Kiln Dust
The utilisation of industrial bi-products such as cement kiln dust (CKD) is of increasing importance as an option for stabilising contaminated sites due to its pozzolanic nature and also in view of minimising the environmental impact. The experimental programme was carried out in the present study to evaluate the efficacy of CKD as stabilising agent at different percentages 2%, 6%, and 14% (w/w...
متن کاملUtilization of Cement Kiln Dust and Fly Ash in Cement Blends in Saudi Arabia
Cement kiln dust produced in a local cement production plant in Saudi Arabia, along with fly ash resulting from combustion of heavy fuel oil in a local power generation plant were utilized as waste materials blended with ordinary Portland cement at various ratios. These blends were tested for their water requirements for normal consistency, initial setting times, and compression and tensile str...
متن کاملCarbon dioxide sequestration in cement kiln dust through mineral carbonation.
Carbon sequestration through the formation of carbonates is a potential means to reduce CO2 emissions. Alkaline industrial solid wastes typically have high mass fractions of reactive oxides that may not require preprocessing, making them an attractive source material for mineral carbonation The degree of mineral carbonation achievable in cement kiln dust (CKD) underambienttemperatures and press...

متن کاملBacterial treatment of alkaline cement kiln dust using Bacillus halodurans strain KG1
This study was conducted to isolate an acid-producing, alkaliphilic bacterium to reduce the alkalinity of cement industry waste (cement kiln dust). Gram-positive isolate KG1 grew well at pH values of 6-12, temperatures of 28-50°C, and NaCl concentrations of 0-16% and thus was further screened for its potential to reduce the pH of an alkaline medium. Phenotypic characteristics of the KG1 isolate...
