Aluminoborate glasses find use as sealants in numerous energy-storage and biomedical devices. However, a primary shortcoming of this glass family is its chemical durability, particularly when they may be exposed to alkaline (aqueous) environments. Th

Alkali-silica reaction (ASR) is a significant cause of the degradation of concrete structures. ASR results from the dissolution of reactive silicate aggregates and the subsequent formation of damaging, expansive ASR gels. Despite the prevalence of AS

Setting and strength development of ordinary Portland cement (OPC) binders involves multiple interacting chemical reactions, resulting in the formation of a solid microstructure. A long‐standing yet elusive goal has been to establish a basis for th

The production of ordinary portland cement (OPC) is a CO2 intensive process. Specifically, OPC clinkering reactions not only require substantial energy in the form of heat, but they also result in the release of CO2; i.e., from both the decarbonation
