Abstract The disintegration of concrete structures made of ordinary Portland cement (OPC) is a worrying topic of increasing significance. The development of new binders with longer durability is therefore needed. Alkali-activated binders have emerged as an alternative to OPC binders, which seems to have superior durability and environmental impact. This paper reviews current knowledge about alkali-activated binders. The subjects of Part 1 in this paper are historical background, terminology and hydration products. The proper terminology to designate these new binders will be discussed. The influence of the prime materials and the type of alkaline activator on the reaction mechanisms and on the nature of the reaction products will be described.

Formation of one-part-mixing geopolymers and geopolymer ceramics from geopolymer powder (2017, positive): “Higher curing temperature speeded up the chemical reaction that directly increases the mechanical properties of geopolymers [10, 41, 42].”
Isothermal reaction kinetics and temperature dependence of alkali activation of slag, fly ash and their blends (2013, methodology): “Among the most researched methods is the activation of aluminosilicate materials such as fly ash or ground granulated blast furnace slag (hereinafter termed slag) using alkali hydroxides or silicates [1–6].”
The effect of glass powder on the microstructure of ultra high performance concrete (2014, background): “suggested a new mechanism explaining the geopolymer formation in alkaline solution [31].”
