AB Belite cements, BCs, containing mainly belite, alite and calcium aluminates, are currently used as low heat cements.These binders produce high amounts of C–S–H gel and have very good durability properties which arereviewed. Additional advantages include: (i) lower limestone demand, with lower associated CO2 emissions; (ii)lower energy demand; (iii) lower kiln operating temperature, which means lowering CO2 and NOx emissionsfrom fuel burning; and (iv) lower temperature increase at early hydration age. However, early-age strengthdevelopments are not competitive with those of Portland cements. Hence, to improve their early-age strengthdevelopments is a research priority known as activation. This enhancement can be attained by three compatibleapproaches: (i) chemical, (ii) physical; and (iii) admixture activations. The current research status for BCsactivation is reviewed including: cost-effective element substitutions to stabilize high-temperature forms; fastcooling, milling and mild temperature hydration as physical activation; and the use of C–S–H seeds as admixtureactivation. After discussion of the resulting microstructures, a research outlook is exercised.

NO The work in Malaga has been supported by BIA2017-82391-Rresearch grant, which is co-funded by FEDER. The work in San Sebastianwas supported by PID2019-105488GB-I00 research grant, the GobiernoVasco UPV/EHU (Project No. IT-1246-19), and the EIG CONCERT-Japan5th Joint Call on Functional Porous Materials (Project No. PCI2019-103657-POROPCM). We thank Buzzi Unicem for providing us with morethan 30 kg of a large-scale production of an active belite cement. We alsothank Fulvio Canonico (Buzzi Unicem) for very helpful discussionsabout industrial aspects of belite cements.
