Influence of various de-icing agents on the durability of concrete products

According to information published by the Bundesverband Straße, Landschaft, Garten e.V. (SLG; Federal Association for Road Construction, Landscaping and Gardening), the 2009-10 and 2010-11 winter seasons caused an increased amount of scaling damage to areas covered with concrete pavers. These particularly hard winters resulted in a widespread shortage of commonly used de-icing salts (i.e. sodium chloride), which suggested the possibility that other de-icing salts may have also been used at least to a certain extent. A study jointly carried out by SLG, VDZ (German Cement Works Association) and...
