It has been observed that certain cement clinkers exhibit a better response with chemical additives than other clinkers regardless of the resulting cements other performance criteria, such as early and late age strength, set time and water demand.These chemical cement additives are generally added at the grinding stage to improve grinding or, as in the cases studied here, improve strength development of certain components of the cement (aluminate, ferrite, silicate phases etc.) and accelerate or retard the hydration.
