Durable advanced Concrete Solutions - Design and construction for coastal and arctic regions

Production and use of concrete structures for severe conditions is challenged based on three main aspects: changing materials due to environmental requirements, climatic changes leading to more severe exposure conditions and human activities moving into new frontiers of construction.

Kvaerner is today world leading on marine offshore concrete structures and aims to further develop commercially competitive, safe, robust and HSE friendly offshore concrete structures for new markets including arctic and other harsh climate areas. Structures located in such areas are subjected to severe frost and ice exposure which implies new types of loads and wear compared to existing experience.

The DaCS project will offer mutual beneficial cooperation between Norwegian home and offshore industry to build strong consortia prepared for high quality, durable and sustainable concrete structures for the future. Combining the needs for knowledge in domestic large concrete structures with the needs of large offshore marine concrete structures will strengthen the Norwegian industry and its competitiveness, as well as our welfare society.

Important innovation and research needs are identified and the following research areas are defined:

• Early age cracking and crack calculation in design
• Production and documentation of frost resistant concrete
• Concrete ice abrasion
• Ductile, durable Lightweight Aggregate Concrete
