Diffusion-reaction model of stochastically mixed sulfate in cast-in-situ piles

This study investigated the diffusion-reaction of sulfate in a cast-in-situ pile after different serving times. The diffusion equation was established based on Fick’s second law, and the model was established via the method of separation of variables by considering the appropriate initial and boundary conditions. An example of the diffusion-reaction of sulfate was compared to a traditional model. Additionally, the validity and advantages of the...
