Grouting is a fundamental ground improvement technique that plays a pivotal role in stabilizing and enhancing the properties of soil and rock formations for construction purposes. It involves injecting a slurry into the soil or rock to enhance engineering properties. Cement grout is a common choice; however, the use of cement is not environmentally sustainable. In this study, an attempt has been made to prepare a sustainable grout mix by utilizing dolomite mine overburden as a partial replacement for cement. To assess the viability of this modified grout mix, the current research investigates the fresh-state properties of the grout mix, such as flowability and bleeding characteristics, as well as its hardened state properties, including compressive strength and drying shrinkage. Variations in the water-cement ratio from 0.35 to 0.45 and the use of a PCE-based superplasticizer in the range of 0.8–1.6% are considered. The findings indicate that replacing cement with dolomite mine overburden significantly improves workability while reducing bleeding properties. Additionally, incorporating dolomite mine overburden enhances compressive strength and reasonably reduces shrinkage. The results demonstrate that replacing 10–15% of cement with dolomite mine overburden is a viable option for sustainable grout mixes. This study suggests that using dolomite mine overburden as a partial cement replacement in grout mixes can be a way toward eco-friendly ground improvement practices.
