摘要：

Computer modelling of time dependences of radon release rate during hydration of 3CaO.SiO2 was carried out. It was demonstrated that the emanation thermal analysis (ETA) can be used for the characterisation of morphology changes during hydration of Portland cement clinker minerals. The presence of various additives and increased temperature affecting kinetics of hydration were simulated by the mathematical model of the radon release rate during hydration of 3CaO.SiO2. A good agreement between the mathematical model and ETA experimental results was found.
