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

Zhang, Shizhe (author), Keulen, Arno (author), Arbi Ghanmi, K. (author), Ye, G. (author)The feasibility of a waste glass powder residue (GP) from glass recycling as partial mineral precursor to produce alkali-activated materials is investigated. GP served as powder coal fly ash (PCFA) replacement within a reference system composed of 50% PCFA and 50% ground granulated blast furnace slag (GGBS). Compared with PCFA, GP was better...journal article 2017
