This thesis investigated the potential of Bauxsol™ based grout and sprayed concrete to reduce acid rock drainage (ARD). The problem of ARD and the current methods to prevent and treat ARD were reviewed. Then, the current cementitious technologies used for and relevant to mining applications were reviewed. An overlap in the treatment and prevention of ARD with cementitious technologies was observed. The cost of, maintenance required and unreliability of current prevention and treatment methods for ARD meant that industry was seeking more effective and reliable solutions for the ARD problem. It was determined that there was potential to use a new filler material (BauxsoITM) in cementitious systems to prevent and treat ARD. Firstly, grouts and sprayed concrete suitable for application in mines were developed. Once the grouts and sprayed concrete were developed they were tested for their interaction with ARD. The success of the ARD was based on how efficiently the grout and sprayed concrete could immobilise deleterious substarices found in the ARD. Findings concluded that there was potential for BauxsoFM based grouts to prevent and treat ARD, however, the limits of the prevention and treatment observed needs to be determined before they are applied in mines. The ultimate success of the Bauxsol™ grouts and sprayed concrete could be determined by replicating the laboratory testing from this study in the field.
