Characterisation of the performance of sustainable grout containing bentonite for geotechnical applications
Abstract
The grouts used in sealing or backfilling boreholes should ideally be selected to be compatible with the insitu field instruments installed in the borehole and also be engineered to match closely the geotechnical properties of the parent soils.A stable grout can be made using cement with various proportions of bentonite.The grout stability is very important during both the liquid and set conditions.The liquid grout fluidity should be as viscous as possible to avoid segregation, yet fluid enough to be easily pumpable and fill voids and over-break in the borehole.This paper investigates the effect of bentonite on the fresh and rheological properties of cement-based grouts in order to develop a stable grout to be used in these geotechnical situations.These properties were evaluated by the mini-slump flow, marsh cone flow time, Lombardi plate cohesion meter, static bleeding, yield stress and plastic viscosity values.Additionally, the compressive strength at 3 days, 7 days and 28 days were also investigated.The key parameters investigated were the dosages of bentonite and water-to-binder ratio (W/B).Test results showed that the dosage of bentonite had a significant effect on the fluidity, rheological properties and compressive strength of grout.The increase in the dosage of bentonite led to increasing the values of flow time, plate cohesion meter, yield stress and plastic viscosity, and reducing the mini-slump results, the static bleeding and the compressive strength at 3 days, 7 days and 28 days.Conversely, the increase in W/B led to decreasing the values of flow time, plate cohesion meter, yield stress, and plastic viscosity and the compressive strength, while increasing the mini-slump results and bleeding.Some recommendations for suitable mix proportions for use in soil boreholes are made.
