Gluth, Gregor J.G. (author), Ke, Xinyuan (author), Vollpracht, Anya (author), Weiler, Lia (author), Bernal, Susan A. (author), Cyr, Martin (author), Dombrowski-Daube, Katja (author), Geddes, Dan (author), Nedeljković, Marija (author)The current ability to predict the carbonation resistance of alkali-activated materials (AAMs) is incomplete, partly because of widely varying AAM chemistries and variable testing conditions. To identify general correlations between mix design parameters and the carbonation rate of AAMs, RILEM TC 281-CCC Working Group 6 compiled and analysed...book chapter 2023

Yang, Zhengxian (author), Shi, Peng (author), Zhang, Yong (author), Li, Z. (author)The influences of liquid-binder ratio and mixing sequence on the performance of superabsorbent polymer (SAP)-containing alkali-activated slag (AAS) mortar are investigated in this study. It is found that the SAP absorbs much less liquid in upper supernatant of AAS than in water. Mixing SAP with liquid first induces a larger absorption...journal article 2022

Zhang, Jingxiao (author), Ma, Yuwei (author), Zheng, Jiazheng (author)The widespread application of alkali-activated fly ash/slag (AAFS) concrete requires satisfaction of a series of performance criteria both from its early age properties (e.g. workability, strength) and long-term stability. In this study, long-term (till 180 days) natural chloride diffusion tests were conducted to evaluate the chloride diffusion...conference paper 2021

Effect of reactive aggregate on the early age reaction of water-glass activated slag/fly ash mortarsWang, Wei (author), Zhang, Shizhe (author), Guang, Ye (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

Keulen, A. (author), Yu, Q. L. (author), Zhang, Shizhe (author), Grunewald, S. (author)This paper investigates the influence of a plasticizing admixture on the pore structure refinement of alkali-activated concrete and paste mixtures and the consequently enhanced performance. Alkali-activated fly ash-slag concrete and paste are designed using a polycarboxylate-based admixture with different dosages. The pore structure and...journal article 2018

Nedeljković, Marija (author), Šavija, B. (author), Zuo, Y. (author), Lukovic, M. (author), Ye, G. (author)The aim of this paper was to investigate the effect of natural carbonation on the pore structure, and elastic modulus (E<sub>m</sub>) of alkali-activated fly ash (FA) and ground granulated blast furnace slag (GBFS) pastes after one year of exposure in the natural laboratory conditions. The chemical changes due to carbonation were examined by...journal article 2018
