Abstract:Visual physical model experiment of aggregates motion law were carried out via transparent adhesive prepared from carbomer gel with equivalent rheological properties of fresh concrete. Based on the principle of consistency in both real time image of flow process and real aggregate distribution from fresh mortar and transparent adhesive, the mechanism of rheological deformation of mortar and aggregate settling characteristics forced vibration was analyzed. Results indicate that visual simulation method of fresh concrete based on equivalent rheological properties is unique and feasible, and from the experiments the aggregates settlement motion law i.e., displacement fields, velocity fields and other motion morphological parameters can be directly obtained，which provide vital foundation on the analysis of constitutive relationship and grain contact model of rheological concrete.
