A comprehensive overview about the influence of different additives on the properties of alkali-activated slag - A guide for Civil Engineer

Abstract

The development of new binders, as an alternative to Portland cement (PC), by alkaline activation, is a current researchers interest. Alkali-activated slag (AAS) binder is obtained by a manufacturing process less energy-intensive than PC and involves lower greenhouse gasses emission. AAS belongs to prospective materials in the field of Civil Engineering. Researchers have employed fibres, chemical admixtures, mineral admixtures and other materials as additives in AAS system aiming to modify some properties of this system. This paper presents a comprehensive overview of the previous works carried out on using different additives in AAS system. © 2013 Elsevier Ltd. All rights reserved.
