Are new magnesia-based cements the future?
Part 1: Analysis of former developments
To decrease CO2 emissions in the cement industry, new cement-based binders are in the focus of attention, especially calcium-based systems, geopolymers and new magnesia binders.
Cement is mainly used for in-situ concrete and prefabricated construction elements made from concrete. To satisfy this demand in Germany more than 80 % of the cement produced is required (Fig. 1). Plaster, mortar and floating screed as well as special binders like adhesives based on cement are quantitatively only of lower...
