Chen, Y. (author), de Lima, Luiz Miranda (author), Li, Zhenming (author), Ma, Bin (author), Lothenbach, Barbara (author), Yin, Suhong (author), Yu, Qijun (author), Ye, G. (author)The synthesis of N-A-S-H gel with high Si/Al ratios (>2) has been rarely reported in the literature, leaving the establishment of a reliable synthesis route as an open challenge. This paper aims to synthesize N-A-S-H gels with Si/Al ratios ranging from 1 to 3 and establish their thermodynamic database. The effects of reaction temperature,...journal article 2024

(author), Yu, Qijun (author), Lothenbach, Barbara (author)New self-healing agents that can chemically bind seawater ions invading cracked cementitious materials were proposed. The potential of self-healing and binding of seawater ions were investigated by thermodynamic modeling. It was found that CaO-NaAlO<sub>2</sub> and CaO-metakaolin agents can have Cl<sup>−</sup>, SO<sub>4</sub><sup>2−</sup> and...journal article 2021
