Autogenous shrinkage is often fully attributed to self-desiccation, or the lowering of internal relative humidity with age. Research at VTT has shown that autogenous shrinkage can still occur even if the humidity is at 100%, immediately after casting. Even before the setting time, measurements of autogenous deformation have been recorded. The presence of very early age autogenous shrinkage was also supported in the physical test arrangement by the development of internal capillary under-pressure. This paper aims at identifying the factors governing autogenous shrinkage during the very early hours.
