The paper discusses the proposed experimental-theoretical approach for estimating the parameters of the macrokinetics of hydration of multicomponent cement systems with partial replacement of cement with silica fume and zeolite. Activation energy parameters are necessary to analyze the reactivity of the components used and to model the process of curing concrete from the standpoint of a model of related physical and chemical processes in reacting media. Isothermal calorimetry is used to determine the macrokinetic parameters of hydration. The calculation results showed the effectiveness of this approach for obtaining information about the activity of the investigated complex binders and their modeling.
