There will be two main aims; the first will be an assessment of the durability of LLC (mainly freeze-thaw durability) by accelerated tests (established, modified or newly designed). The development and documentation of the freeze-thaw method can serve as a foundation for the national annexe to NS-EN 206. The second aim is to establish a long-term durability test site in Narvik harbour to enforce data gained from accelerated testing. The solutions to the issues created by the freeze-thaw cycle encountered in Arctic conditions will be addressed to achieve a suitable evaluation system for LCC. The frost resistance issue is likely the biggest challenge/obstacle in reducing the carbon footprint of concrete. Collaboration between experts from Norway, Sweden, Iceland, Finland and Greenland is beneficial because of their combined expertise and dedication to sustainable concrete technology in Arctic conditions. The Ar2CorD project was submitted for the topic “2.3 Promoting the transition to a circular and resource efficient economy”.
