A Method of 3-D Microstructure Reconstruction in the Simulation Model of Cement Hydration

An accurate and reliable computer simulation system can help practical experiments greatly. In a cement hydration simulation system, the basic requirement is to reconstruct the 3-D microstructure of the cement particles in the initial state while mixed with water. A 2-D SEM/X-ray image is certainly achievable; however, it is not easy to obtain parallel images due to the small scale of the cement particles. In this regard, a method is proposed to reconstruct the 3-D structure from a single microstructure image. In this method, micro-particles are regenerated in a growing trees mode, which by modifying the generating probability of the leaves, the irregularity and the surface fraction of particles can be controlled. This method can fulfill the requirement for the parameters of the 3-D image while assuring that the 2-D image is in full accord.
