Description
Summary:The study is based on durability properties of concrete collected in condition assessments and climate change prediction. According to the prediction facades will face more driving rain in the future because of increasing precipitation and windiness. Outdoor circumstances in southern Finland will ease remarkably already 2030. Initiation by carbonation dominates service life of facades because active corrosion phase is only 5–8years for surfaces exposed to rain. However, sheltered location will remarkably lengthen active corrosion. Properties that influence initiation time are highly important in ensuring eligible service life of the structure. Present requirements are enough also in the future climate but the required cover must always be achieved.
