Application of fundamental research in concrete practice Use of Polymer-modified Concrete in Bridge Construction Part i

In May 2010, a bridge of polymer-modified concrete (PCC) was opened to traffic in the German city of Jena. The application of PCC as structural concrete in practice was made possible by 15 years of research in this field. Concrete mix designs could be determined to meet the specific requirements and in conformity with the standards. Special knowledge is required in particular for calculating the longtime behavior of the structure. As no confirmed detail knowledge is so far available in this area, a bridge was chosen whose geometry was primarily derived under structural aspects and which is subjected to only low loadings. In addition, the factors for describing the long-term behavior were considered with a high safety margin.
