Abstract

Recent incentives to reduce the carbon footprint of Portland cement (PC) concrete have sparked the research and development of eco-friendly products such as alkali-activated slag (AAS) concrete. AAS is a promising product, capable of developing compressive strengths comparable to PC concrete. However, its large drying and autogenous shrinkage (the latter being the focus of this paper) have impeded its marketability and use in the construction industry. The mechanisms and parameters that control the self-desiccation of AAS are relatively unknown. Chemical shrinkage, the driving force of autogenous shrinkage, has never been measured for AAS systems; however, it has been theoretically estimated to be much higher than that of PC. The first step in determining why the autogenous shrinkage of AAS is so large is to investigate its chemical shrinkage. This research focuses on proper measurement of the chemical shrinkage of AAS and the parameters that affect the results.
