Effect of reactive aggregate on the early age reaction of water-glass activated slag/fly ash mortarsWang, Wei (author), Zhang, Shizhe (author), Ye, G. (author), Noguchi, Takafumi (author)Alkali activated materials (AAMs) have received worldwide attention due to its lower embodied energy and environmental impact than that of traditional cementitious materials. However, the activators with high alkalinity may raise the risk of alkali silica reaction (ASR) induced deterioration when reactive aggregates are used, which thereby...conference paper 2021

Zheng, Kunpeng (author), Lukovic, M. (author), de Schutter, Geert (author), Ye, G. (author), Taerwe, Luc (author)This work aims at providing a better understanding of the mechanical properties of the reaction rim in the alkali-silica reaction. The elastic modulus of the calcium alkali silicate constituting the reaction rim, which is formed at the interface between alkali silicate and Ca(OH)2 in a chemically-idealized system of the alkali-silica reaction...journal article 2016

Zheng, Kunpeng (author), Adriaensens, Peter (author), De Schutter, Geert (author), Ye, G. (author), Taerwe, Luc (author)This work is intended to provide a better understanding about the properties and roles of the reaction rim in an alkali-silica reaction. A simplified calcium-alkali-silicate system was created to simulate the multiple interactions among reactive silica, alkaline solution and portlandite near the aggregate surface during the formation and...journal article 2016
