| Abstract: | An introduction was given to some key problems about grout enriched vibrated RCC(GEV-RCC),including the experimental method for GEV-RCC,the optimization of mixing-ratio,the grouting method,and the reasonable amount of grout to be added.The research shows that the fluidity apparatus for cement grout proposed in this paper can reflect the rheological properties of cement grout,and can be applied to field test for optimal determination of the mixing-ratio of GEV-RCC and quality control.Simulation test performed on GEV-RCC by use of three different grouting methods under different grouting ratios shows that it is an effective measure to determine reasonable grouting method and mixing-ratio for GEV-RCC. |
