This study focuses on the composite cementitious materials containing recycled brick powder (RBP) with different Portland cement contents. The effect of RBP on the hydration mechanism of cement-based materials is studied by constructing RBP-cement composite cementitious materials. The hydration products of the composite cementitious materials are analyzed. The hydration thermodynamic model of the composite cementitious materials is established by combining the relevant thermodynamic database, the law of conservation of mass and the minimization of Gibbs free energy principle. Based on reasonable assumptions, the composition of RBP is divided, and the hydration thermodynamic model of the composite cementitious materials is established. The accuracy of the model is verified by the experimental data.
