Abstract Focusing on the problem of real-time prediction of shear modulus of wet-mix shotcrete during the spraying adhesion process, the model derivation work was carried out based on the actual working process of the rotational rheometer. It was found that the aggregate movement and the paste flow were the fundamental behaviors of the shearing movement of concrete. Then the parallel interaction relationship between paste and aggregate was established. The technical parameter “equivalent shear modulus of aggregate movement” was invented, and its calculation expression was derived, achieving the quantitative characterization of paste driven aggregate movement and aggregate blocking paste flow. A prediction model of shear modulus based on the two-phase composition was constructed, and its applicability was discussed. Eight sets of rheological tests were executed to verify the model, the correlation index R² between the measured data and the prediction data was 0.982 9, indicating a good agreement.

Key words： wet-mix shotcrete shear modulus two-phase aggregate movement
