Recycling of geopolymer waste: Influence on geopolymer formation and mechanical properties

Materials & Design, 2016
Abstract Geopolymers are new binders resulting from the activation of an aluminosilicate source by an alkaline solution. These binders are economically and environmentally profitable since they have the advantage of reusing recycled waste and industrial by-products as aluminosilicate sources.
