Abstract: 
Cement bentonite grouting is used to seal and stabilize soil or rock formations. This involves mixing cement, bentonite, and water to create a slurry that is pumped into the ground under pressure. The slurry fills voids and fractures in the soil or rock, creating a solid mass that can support the structures or prevent water from seeping through. Bentonite is a type of clay that swells when it meets water, making it an effective sealing material. Cement is added to the mixture to provide strength and stability. The ratio of cement to bentonite varies depending on the specific application. Different researchers have studied CB slurry properties over the long term. There is a lack of studies done to discover the early age strength of CB slurry with different cement percentages. The objective of this study is to investigate the compression resistance of CB slurry at early ages for different percentages of cement (10-15-20) percent at curing times of 3 and 7 days.
