Are new magnesia-based cements the future?
Part 2: Novacem – an assessment of new 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.

Over the past 170 years concrete based on Ordinary Portland cement (OPC) is the material basis of the construction industry. Next to water concrete is the globally most used material nowadays [1]. During the last decade the global cement industry showed annual growth rates of 7 % and more. A further increase in cement consumption is predicted for the future. However, climate protection is posing new requirements on cement production and demands innovative solutions since the production of cement is associated with high CO2 emissions. As indicated in [2], the cement industry has exhausted all...
