Abstract: The construction of tunnels involves massive excavation work and generates an enormous amount of waste slag. The improper disposal of the waste slag may cause environmental pollution. The treatment of waste slag is usually costly. In this study, the feasibility of recycling waste slag as a component in the synchronous grouting material was investigated. A series of experimental measurements were conducted to evaluate the performance of grouting material with different proportions of recycled waste slag. The experimental results show that the grouting material with the selected proportion of recycled slag has a similar performance to the original grouting material mix. It was observed that waste slag can be recycled as one component of the grouting material for tunneling engineering.
