Important results from the project
** Denna text är maskinöversatt ** The purpose of this feasibility study was to evaluate the effects of using corrosion-resistant reinforcement in concrete structures. The effects evaluated were to reduce weight and reduce COSTs.
Expected long term effects
The result of the feasibility study is that corrosion-resistant reinforcement makes it possible to reduce the area on an edge bolt by about 17% while increasing the service life. For a bridge deck slab, it is possible to remove insulation and asphalt pavement, which can reduce weight by about 25-50%. This is possible by using corrosion-resistant reinforcement.
Approach and implementation
The feasibility study was carried out by the research actors RISE and KTH together with industry partners. The project was divided into different work packages that included, for example, literature studies on chloride threshold values for corrosion-resistant reinforcement and chloride transport properties for different types of concrete. Simpler calculations were also performed to evaluate the effects of corrosion-resistant reinforcement with respect to an edge beam and a bridge deck slab.
