Abstract: The object of this research work is the investigation of the influence of hydrophobic treatments on the freeze thaw resistance of young pavement concrete.
Concrete pavements are often cast until the end of the year. These concrete pavements are exposed to a number of detrimental environmental effects very soon after casting. Simultaneously, physical and chemical attacks due to frost and de-icing agents as well as mechanical attacks due to traffic cause a high strain in the concrete, especially on busy streets.
In order to assure a reasonable technological process of pavement production the impregnation is carried out directly or short time after casting.
The state of research presented here focuses on the examination of young impregnated pavement concrete with respect to capillary water uptake during the pre-saturation as well as during freezing and thawing attacks and with respect to the influence on the provoked scaling behaviour. The influence of different pre-storage conditions on the effectiveness of various hydrophobic agents is investigated here.
