    Abstract:

    A volume fraction prediction method of hydration products of the paste containing silica fume with low water to binder ratios was proposed, which considered the cement hydration mechanism and silica fume reaction mechanism with low water to binder ratios and modified the shrinking-core model. The comparison of calculation results of the proposed method, expeimental results and theoretical results of Power Model and Jensen Model showed that the proposed method was capable of simulating the hydration process and predicting volume fractions of different hydration products well; When no silica fume was mixed, volume fractions of unhydrated cement and chemical shrinkage calculated by the proposed method were basically the same as that of Power Model while volume fractions of hydration products of the proposed model were close to that of Jensen Model with silica fume.
