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.

1 Introduction

Modern construction materials are based on the hydrau­lic binder Portland cement, mainly used for manufacturing concrete and next to water, the globally most used material. Currently worldwide more than one tonne of concrete is produced per capita every year.

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...
