Effect of Nano-silica on Fresh Properties and Rheology of Grouts
The effect of colloidal nano-silica on the fresh and rheological properties of cement-based grouts is investigated in this paper. These properties were evaluated by the mini-slump flow, marsh cone flow time, Lombardi plate cohesion meter, yield stress and plastic viscosity values. The key parameters investigated were the dosages of nano-silica and superplasticizer. Test results showed that the dosage of nano-silica had significant effect on the fluidity and rheological properties of grout. The increase in the dosage of nano-silica led to increasing the values of flow time, plate cohesion meter, yield stress and plastic viscosity, and reducing the mini-slump results. Conversely, the increase in the dosage of superplasticizer led to decreasing the values of flow time, plate cohesion meter, yield stress, and plastic viscosity, while increasing the mini-slump results.
