摘要：
Despite the advances in studies utilizing industrial, construction and agricultural wastes as alternative materials for concrete making, there are still gaps to be covered on the durability characteristics of most materials. This study presents a shot overview on the durability properties of alkali-activated slag (AAS) composites. The durability properties of AAS explored include permeability, alkali silica reaction, carbonation, freeze and thaw, fire resistance, corrosion, and resistance to sulphate, chloride and acid attacks. The research outcomes indicated that AAS possessed strong durability characteristics in terms of resistance to acid and sulphate attacks, however, areas such as permeability, alkali silica reaction, carbonation and freeze-thaw resistance, have not been overly explored. A general overview of the performance and limitations of AAS has been provided, and the study suggested specific areas for further investigations. The information provided in this study will be useful for users of AAS, and pave way for innovative researches on AAS composite.
