“…1b) for use as a supplementary cementitious material (SCM). The main constituent was SiO 2 (59.63%), along with other acidic oxides such as Al 2 O 3 (18.51%) and Fe 2 O 3 (5.92%), (Asensio et al, 2016a;Domínguez et al, 2016;Sassoni et al, 2016) which prevail in other pozzolanic materials as well (Gholhaki et al, 2018;Medina et al, 2016;Mikhailenko et al, 2018). The sulfate content was much lower in this C&DW than in OPC.…”

“…Two-part binders are the option most thoroughly analyzed in the scientific literature on alkaline activation (Hwang and KuoWang, 2011;Nematollahi et al, 2015;Sassoni et al, 2016;Fang et al, 2018;Tigue et al, 2018;Fernández-Jimenez et al, 2019b;Wang et al, 2019;Fang and Zhang, 2020) and have been successfully used in a number of technological applications (Palomo et al, 2007;DB Group, 2018;ZEOBOND, 2020). One large scale example can be found in the over 30,000 m 3 of a zero Portland cement concrete (denominated earth-friendly concrete, EFC) laid by the Australian firm Wagners for works at Brisbane West Wellcamp Airport in 2014 (ENGINEERS Australia, 2020).…”

This review undertakes rigorous analysis of much of the copious literature available to the scientific community on the use of alkali-activated binders (AABs) in construction. The authors’ main intention is to categorically refute arguments of that part of the scientific community underestimating or even dismissing the actual potential of AABs as alternatives to Portland cement (PC). The main premise invoked in support of those arguments is a presumed lack of material resources for precursors that would make AAB industrial-scale production unfeasible anywhere on the planet (a substantial number of scientific papers show that the raw materials required for AAB manufacture are in abundance worldwide). The review also analyses the role of alkaline activators in the chemistry of AABs; it is important to clarify and highlight that alkaline activators are not, by any means, confined to the two synthetic products (caustic soda and waterglass) mostly employed by researchers; other sustainable and efficient products are widely available. Finally, the review deals with the versatility of AAB production processes. The technologies required for the large scale manufacturing of AABs are mostly already in place in PC factories; actually no huge investment is required to transform a PC plant in a AAB factory; and quality and compositional uniformity of Alkaline Cements (binders produced through an industrial process) would be guaranteed. The last conclusions extracted from this review-paper are related with: i) the low carbon footprint of one-part AABs and ii) the urgent need of exploring standardization formulas allowing the commercial development of (sustainable) binders different from PC.
