The Impact

In laboratory conditions, the effect of minor oxides – MgO and SO3 on formation of Portland cement clinker was observed. The research extended the current knowledge about the effect of these oxides on phase composition and structure of clinker and on alite polymorphism. Mainly means of optical and electron microscopy were used for the research.

The Impact

The article focuses on the impact of waste marble powder on resulting cement composites. We investigate of influence waste marble powder on the hydration process and hence the resulting phase composition. The hydration process was investigated using calorimetry and phase composition of the resulting composite by electron microscopy. The results are compared with a reference sample composed of Portland cement.

Sludge Recycling

The comprehensive methodology for the zinc extraction from sulfide compounds into the oxide form with possible further reduction to metal is presented in this study. It was demonstrated in laboratory conditions during sludge treatment with Zn and ZnO obtaining. The remaining silicate products. It is proposed to recycle this material into Portland cement clinker to ensure a waste-free process. Keywords: zinc sulfide, zinc oxide, sludge recycling, Portland cement clinker, waste-free recycling
