Alkali-activated binders: A review. Part 2. About materials and binders manufacture

This paper summarizes current knowledge about alkali-activated binders, by reviewing previously published work. As it is shown in Part 1, alkali-activated binders have emerged as an alternative to (ordinary Portland cement) OPC binders, which seem to have superior durability and environmental impact. The subjects of Part 2 of this paper are prime materials, alkaline activators, additives, curing type and constituents mixing order. Practical problems and theoretical questions are discussed. Topics for future work in this field are suggested. (C) 2007 Elsevier Ltd. All rights reserved.
