Examining the 'time-zero' of autogenous shrinkage in high/ultra-high performance cement pastes

摘要

The term "Time-zero", i.e., the time for the start of autogenous shrinkage measurement, is usually used for estimating the cracking potential of structural components. Accurate determination of the "time-zero" is therefore critical for autogenous shrinkage measurement, which is the main objective of this study.
