Abstract Fluid-solid phase transition characteristics of quick-setting grout has an obvious effect on rock fissure grouting diffusion. With the objective to study rock fissure grouting diffusion mechanism of quick-setting grout，cement- sodium silicate grout(C-S grout) was regarded as the typical quick-setting grout in this paper. Bingham rheological constitutive model with yield stress and viscosity changing with reaction time simultaneously was adopted to describe fluid-solid phase transition characteristics of quick-setting grout. Time-dependent equations of yield stress and viscosity of C-S grout were acquired based on laboratory test. Rock fissure grouting diffusion model of quick-setting grout was established. Rock fissure grouting simulation tests of C-S grout with constant injection rate were done. Injection pressure and spatial distribution of grout pressure in whole grouting process had been acquired. Verification of theorical model had been done based on test results. Temporal and spatial distribution characteristics of grout yield stress and viscosity in grouting region were analyzed. Variation law of calm water resistance，fluid phase resistance and solid phase resistance in grouting diffusion process were acquired. Results show that：Relationship between shearing stress and shearing rate of C-S grout is in good agreement with Bingham rheological constitutive model. With cement to sodium silicate volume ratio increasing，starting and ending time of fluid-solid phase transition shorten significantly. Furthermore，peak value of yield stress and viscosity increase markedly. Contrast to test results，theoretical calculation error of injection pressure based on Bingham model with time-varying yield stress and viscosity，Bingham model with fixed yield stress and Newton model were 12.73%–19.62%，20.12%–29.44% and 21.84%–31.35% respectively. For calculation of rock fissure grouting diffusion process，Bingham model with time-varying yield stress and viscosity is the best model of the three models. In whole grouting process，fluid phase resistance increases rapidly and then decreases slowly. Solid phase resistance increases approximately linearly. C∶S volume ratio has little effect on proportion value of fluid phase resistance and solid phase resistance at ending moment of grouting process，with proportion value of fluid phase resistance and solid phase resistance are 81.7%–82.9% and 15.7%–17.3% respectively.
