dc.description.abstract | 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 are reviewed. 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 emissions from fuel burning; and (iv) lower temperature increase at early hydration age. However, early-age strength developments are not competitive with those of Portland cements. Hence, to improve their early-age strength developments is a research priority known as activation. This enhancement can be attained by three compatible approaches: (i) chemical, (ii) physical; and (iii) admixture activations. The current research status for BCs activation is reviewed including: cost-effective element substitutions to stabilize high-temperature forms; fast cooling, milling and mild temperature hydration as physical activation; and the use of C–S–H seeds as admixture activation. After discussion of the resulting microstructures, a research outlook is exercised. | es_ES |
dc.description.sponsorship | The work in Malaga has been supported by BIA2017-82391-R research grant, which is co-funded by FEDER. The work in San Sebastian was supported by PID2019-105488GB-I00 research grant, the Gobierno Vasco UPV/EHU (Project No. IT-1246-19), and the EIG CONCERT-Japan 5th Joint Call on Functional Porous Materials (Project No. PCI2019- 103657-POROPCM). We thank Buzzi Unicem for providing us with more than 30 kg of a large-scale production of an active belite cement. We also thank Fulvio Canonico (Buzzi Unicem) for very helpful discussions about industrial aspects of belite cements. | es_ES |
