The incorporation of Cu into the clinker phases.

The effect of CuO addition on the phase composition of clinker and the Cu incorporation into the structure of clinker phases was monitored under laboratory conditions. Separate synthesized CuO-doped clinker phases as well as clinkers with different CuO content up to 4 wt.% were characterized by XRD, optical and electron microscopy with EDS analysis.

The role of CuO on the microstructure and phase composition of SO -activated clinker.

The mineralising effect of CuO on microstructure and phase composition of SO -doped clinker was studied by a combination of phase analysis, light and scanning electron microscopy and QXRD. Results show proportionally higher C AF content in clinker interstitial matter due to CuO doping. CuO also lowers the SO incorporation in main clinker phases C S and C S.
