Abstract: The hydration process of cementitious materials play an important role in determining the material’s microstructure formation and properties. Compared to the normal concrete, the hydration process of ultra-high performance cementitious materials is different due to the special components and production process. Taking superplasticizers, water to binder ratios, silica fume and temperatures into consideration, the compensation factors were proposed and an improved kinetics hydration model was established based on the shrinking-core model. The modified and unmodified model was employed to study differences of the hydration process. The model predicting results were compared with the experimental results. Results show that the proposed model is capable of simulating the hydration process of ultra-high performance cementitious materials well.
