The efficiency of the mechanochemical activation (MCA) is influenced by various process parameters as well as by the properties of the treated material. The main objective of this research was to optimize the MCA process, gaining enhancement of the chemical reactivity of a Swedish raw clay, which is going to be used as an alkali-activated cementitious binder.

The process ruptures some of the cavities, and exposes the water to evaporation. More com-monly, the grinding process results in an increase in moisture content due to an increase in surface area available for absorption of atmospheric water. Both of these conditions will affect the analysis of
