Moisture distribution in screeded concrete slabs

Åhs, Magnus LU orcid and Sjöberg, Anders LU (2008) In Nordic Concrete Research 2. p.169-182
Abstract
A qualitative model of moisture distribution in screeded concrete slabs is presented. From this model it is possible to identify humidity changes in each material and thus determine corresponding moisture properties. The distribution of relative humidity, RH, was determined in nine screeded concrete slabs before flooring and after a certain time of redistribution. Moisture redistribution is clearly demonstrated in the results section, where the increase in humidity beneath the flooring is exemplified. The initial moisture distribution and subsequent changes agreed with the presented qualitative model. This model may be used to develop current moisture distribution prediction tools further by introducing a more complex interrelation between... (More)
