Abstract

This study established the fundamental relationships between slag chemistry and reaction kinetics of sodium carbonate-activated slag. The application of the smart chemical addition CLDH for sodium carbonate-activated slag based on the understanding of slag chemistry, has not only made the sodium carbonate activator a plausible option for implementation, but more of a better option with performance advantages. The knowledge developed in this study about the ionic interaction between chlorides and individual reaction product filled in gaps in literature, and becomes a useful tool whose usage is not limited to tailing of sodium carbonate-activated slag, but also for optimising mix design of all types of AAS for achieving better performance.
