Laser radiation scattering by the cement in the process of setting and hardening

This report is devoted to simulation of speckle field dynamics during coherent light scattering by the cement surface in the process of setting and hardening. Cement particles are represented by the spheres, which sizes and reflection indexes are changing during the hydration process. The study of intensity fluctuations of scattered coherent radiation – it is a technique, that is quite suitable for the analysis not only fast, but also slow processes of mineral binders hydration and polycrystalline structures creation in the process of hardening. The results of simulation are in good agreement with the experimental results.
