The cement industry has been estimated to produce 5 of global CO 2 emissions or about 1.4 billion metric tons a year. While many manufacturers have worked to improve energy efficiency at their plants and modified their cement mixes to reduce CO 2 production these decreases have been offset worldwide by increased concrete use in China and India.

This review will show that low-CO2 cements can be produced to give superior durability based on a sound understanding of their microstructure and how it impacts macro-engineering properties. For example it is essential that aluminium is available in calcium-rich alkali-activated systems to offset the depolymerisation effect of alkali cations on C-(N-)A-S-H gel.
