Workability study of sand-bentonite-cement mixtures for …
A seepage cut-off wall with a low permeability is usually constructed in soil, especially in sandy layer, to prevent groundwater seepage through for various civil engineering projects, e.g. dam, dike, and excavation of underground space [1], [2], [3].Bentonite is widely used in construction of seepage cut-off wall to reduce the …
Soil-Cement-Bentonite Slurry Walls | Proceedings | Vol, …
Soil-Cement-Bentonite (SCB) slurry walls have been used with increasing frequency in recent years to provide barriers to the lateral flow of groundwater in situations where the strength of a normal soil-bentonite wall would be inadequate to carry foundation loads. The addition of cement to the backfill blend allows the backfill to set and form ...

Crack-resistant cement–bentonite cut-off wall materials …
Preserving the integrity of cement–bentonite cut-off walls, particularly in aggressive environments, is critical to their serviceability in polluted sites. The hardened cement–bentonite material in cut-off walls is highly susceptible to desiccation and wet–dry cycles, commonly leading to cracking. The objective of the work presented in this paper …

Reuse of Excavated Clayey Silt in Cement–Fly Ash–Bentonite Hybrid Back
Excavated soils from tunnel construction need high treatment cost and pollute the environment. To investigate the feasibility of excavated clayey silt reused in back-fill grout, the flowability, stability and strength were taken as measurement indexes of grouting performance. The clayey silt was tested to be reused as substitutes for fly ash, …
Cement-Bentonite Grout Backfill for Borehole Instruments
When water and cement are mixed first, the water-cement ratio stays fixed and the strength/modulus of the set grout is more predictable. If bentonite slurry is mixed first, the water-cement ratio cannot be controlled because the addition of cement must stop when the slurry thickens to a consistency that is still pumpable. Making cement ...
Grouting Bentonite, and Cements
The cement-water ratio controls the strength of the grout. To decrease the strength of the grout, add more water. Drillers are accustomed to mixing water and bentonite first, but this will not allow you to control the water-cement ratio. Mix water and cement first. Then add bentonite. There is no particular amount of bentonite that you must add ...
