What is Expansive Admixtures in Concrete about?
This document discusses expansive admixtures used in concrete, specifically those containing ettringite. It describes the hydration chemistry that causes ettringite and other components like monosulfate and calcium hydroxide to expand when they form. This expansion can be used to compensate for concrete shrinkage and create "shrinkage-compensating concrete" or "chemical prestressing concrete". The document also provides examples of the volume changes that occur during hydration of expansive components.
