Analyzing the filling performance parameters of self-compacted mortar in rock filled concrete

Rock-filled concrete RFC is a prospective construction material whose quality is affected by the filling performance of self-compacting concrete SCC in granular packs. This study focuses on improving the inclination factor equation, taking into account previously overlooked limitations. The analysis of the filling behavior of SCC in granular packs is explored through the developed numerical models. Computational fluid dynamics CFD software OpenFOAM is conducted for simulations and calibrated with experimental data. These models consider self-compacting mortar SCM with different yield stresses poured into porous media with diverse grain shapes, sizes, and stacking modes. The concluded equation aims to provide a more precise description of SCM flow in granular packs which influence the future RFC construction projects and future studies of the filling assessment of SCM.
