Abstract

In this study about internal curing of High Performance Concrete, X-ray absorption showed that considerable transport of water from saturated lightweight aggregates (pumice) to hydrating cement pastes (w/c ratio 0.3) took place in the first days after casting and covered a distance of at least 4 mm. As a consequence, the amount of water released by the lightweight aggregates, rather than the spatial distribution of the aggregates, is in this case the crucial factor to avoid early-age self-desiccation shrinkage.
