This research project aims to improve the durability and resistance to freeze thaw cycles of colored concrete. The goal of this study is to study the effect of the red pigment on the frost-thaw resistance of concrete and to evaluate possible improvement actions by adding super absorbing polymers (SAPs) to the fresh mix. Also the combined effect of frost-thaw with de-icing salt is investigated. By means of a laboratory investigation the influence of the red pigment on the scaling and degradation due to frost-thaw cycles is investigated according to the standard ISO/DIS-4846-2 and by means of compressive strength tests, measurements of the weight loss due to scaling and scanning electron microscopy. Secondly, the effect of various amounts and different types of SAP added to the fresh mix is studied and evaluated by means of the previously mentioned testing equipment. |
