To deal with the problems such as grouting pipe blocking and uneven diffusion of grout-enriched roller compacted concrete, the rheology, fluidity, stability, strength and time-varying properties of slurry containing micro-silica powder were studied. The entropy weight ideal point method was used to determine the optimal mix proportion by considering the working characteristics of the slurry and economic cost. The results show that adding micro-silica powder can reduce the bleeding rate and improve the compressive strength. When W/B=0.4, micro-silica powder reduces the yield stress and fluidity, and increases the plastic viscosity. When W/B =0.5-0.7, the yield stress and plastic viscosity increase with the addition of micro-silica powder. The rheology of slurry is related to the thickness of water film. With the increase of water-binder ratio, the effect of micro-silica powder on slurry’s performance gradually weakens. The yield stress increases linearly with time, and the plastic viscosity increases exponentially with time. Based on entropy weight ideal point method, the optimal mixture ratio of different schemes with fixed water-binder ratio can be obtained.
