The aim of this study was to investigate the construction and demolition waste (CDW) fine size fraction by increasing its reactivity with mechanical activation (MA) in a stirred media mill. Systematic measurements were carried out in order to gain information about its reactivity. Particle size distribution and BET specific surface area measurements were carried out as dispersion properties. The changes in the particle shape and surface were measured by scanning electron microscopy (SEM), and structural alteration was investigated by FTIR spectroscopy and X-ray diffraction (XRD). The effect of MA on the pozzolanic reactivity was measured by lime sorption as well as strength tests. As a result of the research, it was found that reactivity of the construction and demolition waste (CDW) fine size fraction could be controlled by MA in a stirred media mill.
