Geopolymers are cementitious materials with three dimensional structures that are formed by chemical activation of Al and Si containing solid materials at relatively low temperatures. Several wastes or by-products, including coal combustion ashes, metallurgical slags, construction and demolition wastes can be utilized for the production of geopolymer concrete and construction components. The present paper outlines briefly the potential of geopolymer technology towards green buildings and future sustainable cities with a reduced carbon footprint.Δημοσίευση σε επιστημονικό περιοδικό http://creativecommons.org/licenses/by/4.0/Procedia Engineering211023–1032 Komnitsas Konstantinos Κομνιτσας Κωνσταντινος Elsevier geopolymer sustainable building carbon footprint life cycle analysis
