Keywords: concrete casting, fresh concrete, moving particle simulation, numerical simulation, thermal diffusion.
The work, described in this paper, proposes an approach for the simulation of the concrete flow inside forms concurrently with the temperature elevation of concrete due to the hydration process and the heat dissipation through the material. It is based on the moving particle semi-implicit (MPS) method, a meshless Lagrangian particle based simulation method that uses the governing equations for incompressible flows. The Lagrangian approach of the MPS method make it suitable to simulate free surface flows with large deformation, fragmentation and merging, and problems that involve complex geometry, which is the case of concrete casting in forms with complex geometry or highly reinforced pieces.
