This article reviews proposed technical approaches for the manufacture and use of alternatives to Portland Cement Clinker as the main reactive binder component for ordinary concrete construction in non-specialty applications, while giving lower net global CO{sub 2} emissions in use. A critical analysis, taking into account a wide range of technical considerations, suggests that, with the exception of alkali-activated systems, (treated in a separate paper in this issue,) there are only four classes of alternative clinker system that deserve serious attention with respect to global reductions in concrete-related CO{sub 2} emissions:(A)Reactive Belite-rich Portland cement (RBPC) clinkers (B)Belite-Ye'elimite-Ferrite (BYF) clinkers (C)Carbonatable Calcium Silicate clinkers (CCSC) (D)Magnesium Oxides derived from Magnesium Silicates (MOMS) A and B are “hydraulic” clinkers, (i.e. clinkers which harden by reaction with water,) C is a “carbonatable” clinker, (i.e. one which hardens by reaction with CO{sub 2} gas) and D can fall into both categories.
