Abstract

BERNAL, Susan A.; MEJIA DE GUTIERREZ, Ruby  and  RODRIGUEZ, Erich D.. Alkali-activated materials: cementing a sustainable future. Ing. compet. [online]. 2013, vol.15, n.2, pp.211-223. ISSN 0123-3033.

This paper presents an overview examining the microstructural and macrostructural properties of alkali-activated binders based on granulated blast furnace slags, metakaolin and their blends, developed by the Composite Materials Group of Universidad del Valle over the past decade. Durability results of activated binders when exposed to aggressive agents such as chlorides, and carbon dioxide are reported. The results of this research have elucidated the great feasibility of adopting alkali-activation technology in Colombia for producing high strength concretes based on industrial by-products, with a wide range of properties that can be suitable for different civil infrastructure applications, and contribute to the valorization of low-cost industrial by products through production of more environmentally friendly building materials. Our research highlights the fact that a deep understanding of the chemistry of these systems allows the manipulation of the microstructure and therefore the performance of the final products, toward the production of sustainable and versatile materials

Keywords : Alkali-Activation; blast furnace slag; Metakaolin; compressive strength; durability.
