Abstract
To quantitatively estimate the workability of cement-based grouting material, from the perspective of rheology, the result of the static yield stress evaluated using the rate-controlled and stress-controlled modes, respectively, was compared using the Rheowin rheometer. Also, the correlation of workability and solid concentration of slurry with static yield stress was studied. Results show that the static yield stress of cement-based grouting slurry relates to the established slurry structure, and is the shear stress corresponding to the transformation of elastics to plastics; In rate-controlled mode, the static yield stress of the slurry is related to the shear rate. The higher the shear rate, the greater the yield stress of the slurry. For the stress-controlled mode, the result is more accurate and suitable for testing static yield stress under different water-cement ratios. Since the water-cement ratio has a good correspondence with the static yield stress and the static yield stress has a good correspondence with the slump flow of the slurry, the static yield stress is the minimum stress to be overcome when the slurry begins to flow and it reflects the yield behavior and structural stability of the cement.
