Hydroxide ion concentration at an interface between concrete and a self-levelling flooring compound

Författare

Summary, in English

This article presents results from measurements of hydroxide ion transport between a concrete and a floor screed of a lower alkalinity than the concrete. As many floor coverings and floor adhesives are sensitive to high alkaline conditions it is important to know how hydroxide ions are transported to be able to evaluate the long-term function of floor constructions. It was found that only minor transport of hydroxide ions occurs in the hygroscopic moisture range. One conclusion is therefore that a floor screed of lower alkalinity may protect sensitive floorings from the high alkalinity present in concrete.
