Alkali activated binders (AAB) are gaining huge research attention in recent years, due to their potential to totally be used in a zero-cement composite. Ordinary Portland cement (OPC) is characterized by high energy usage and carbon emission from its production process, which thus shows the need for AAB development. AAB are a sustainable replacement for OPC, as they can be produced from waste materials generated by various industrial processes. This paper explored the properties of different types of waste used as a solitary and binary combination for AAB, alongside their effects on the resulting composites. A general summary of the opportunities of AABs are also discussed. It was concluded that, with more research and developments dedicated to the field of AAB, AAB can be practical replacement of OPC for large-scale applications in the near future.
