Abstract: The primary objective of this research was to evaluate the performance of low pressure grouting with the partial replacement of cement by copper slag in treating soft marine clay. This research consists of two parts. In the first part of research, pozzolanic property of copper slag was evaluated. The effect on engineering properties and microstructural property of cement-treated clay was discussed with increasing amount of copper slag. The results show that copper slag can be used as partial replacement of cement in treating soft marine clay. In part 2, performance of low pressure grouting (i.e. via radius of grouted column) was evaluated with cement-copper slag grout by using laboratory grouting apparatus. Based on low pressure grouting experimental data, a new model was developed for evaluation and prediction of the diameter of grouted column. It was found that this model can provide a fairly accurate prediction of radius of grouted column. The diameter of grouted column was then evaluated by using this new model in low pressure range (3 to 5 MPa) and compared with that of field trial of high pressure jet grouting. It was found that diameter of grouted column achieved in low pressure grouting fall within the lower range of that of jet grouting.
