| 요약 | Coal ash is a by-product of coal combustion process in power plants. A significant portion of the generated coal ash is disposed of in impoundments and landfills. Gradual deposition of coal ash can induce excessive shear stresses and lead to int |
| 요약 | Factors affecting the kinetics and chemistry of MICP reactions are studied using chemical equilibrium modeling and experimental batch testing. A column testing program was performed to optimize MICP treatment recipes and to develop MICP treatmen |
| 요약 | Monitoring the shear wave velocity of the MICP treated specimens of the studied coal ash materials showed three different responses, while treated identically. Two of the studied ash materials exhibited significant improvement in stiffness durin |
| 요약 | The large-strain results in modified consolidation setup demonstrated a reduction in compressibility (CC and mv) for treated coal ash in comparison to untreated material. This reduction was more at lower levels of applied vertical stresses. The |
| 요약 | Lastly, based on the combined results of adsorption/ desorption chemical equilibrium and batch testing, a backbone curve which correlated the arsenic solubility to pH of the solution was proposed. Comparing the backbone curve and leaching result |
