RIBuild: Laboratory based investigations of the materials' water activity and pH relative to mould growth

This dataset contains measurements of relative humidity and temperature in small test walls, from mycometer test and from measurements of moisture content in materials in the test walls.

The objective of the study is to find the causes and conditions that lead to mould growth between a existing wall and installed insulation systems, and to suggest solutions to prevent mould growth.The study examines whether the alkaline environment (pH> 9), which may occur in the adhesive glue joint between the existing wall and the installed insulation is sufficient to prevent mould growth,even if the moisture (water activity (aw)) at the interface exceeds the levels (aw> 0.75) commonly considered critical for mould growth.

The dataset also contains extensive photo documentation of preparations and carrying out the experiments.
