Reaction mechanisms of sodium carbonate activation in ultra-high-volume slag-cement blends
Samira Hossain, Zhanzhao Li, Kai Gong
Ultra-high-volume slag-cement (UHVS) blends can substantially reduce clinker ratio, but slow slag reaction limits strength development; Na2CO3 is a less caustic and lower-carbon ac…

Gel-Chemistry-Controlled Heavy-Metal Transport and Retention in Cementitious Gel Nanopores: A Molecular Dynamics Study
Weiqiang Chen, Qiyao He, Kai Gong
Cementitious materials are widely used for hazardous-waste encapsulation, yet molecular mechanisms governing heavy-metal ion retention across gel chemistries remain insufficiently…
