In the prepacked concrete practice, the process that the voids of preplaced coarse aggregate become filled up with the mortar depends on the shape and dimentions of the structure and the grouting conditions. A theoretical method for predicting this process was studied. From the hypothesis that the grout flows through the voids obeying the Darcy's law, the shape of the mortar surface was obtained as the solution of the equation of diffusion and expressed by Green's functions, which included the whole parameters above mentioned. The calculation results for a wall, four rectangular blocks, and a cylinder under different grouting conditions agreed well with the experimental values. An example of a large scale rectangular foundation was also calculated.
