What is Importance of Self-Desiccation in Concrete about?

This document summarizes research into very early age (first few hours) autogenous shrinkage in concrete. The key points are: - Autogenous shrinkage can occur even at 100% internal relative humidity, before self-desiccation would take place. - In the first liquid stage after casting, all volume change is vertical (settlement). Around setting time, autogenous shrinkage is equal in magnitude to chemical shrinkage. - Early autogenous shrinkage increases with lower water-cement ratio, lower aggregate conte
