Abstract: The object of the present study is the kinetics of cement strength development using different cement and aggregate types. The model that has been developed uses the following data: (1) Composition of cement. (2) Mineral composition of clinker. (3) Cement fineness. (4) Early, standard and long-term strength data. (5) Aggregates nature. The parameters of the model are constituted by: (1) The hydration rates of the mineral phases of clinker that are a function of the cement fineness. (2) The contribution of each phase to the cement strength. As far as the hydration of phases is concerned first order kinetic has been used. The parameters of the model were calculated through fitting to experimental points of strength for the cement types CEM I and CEM II A-L produced in the factory of HALYPS. Siliceous and calcareous aggregates were utilized. The effect of the clay, sometimes existing in the concrete aggregates is also investigated and incorporated in the mathematical!
treatment. . The impact of the aggregates type on the mortar strength development and variance is linked with physical characteristics of the aggregates. The mathematical model can be utilized for the cement composition design, as well as a quality control tool for regulation of the current production
