1. Durability of fire exposed concrete : Experimental Studies Focusing on Stiffness & Transport Properties
Sammanfattning : Road and rail tunnels are important parts of the modern infrastructure. High strength concrete (HSC) is commonly used for tunnels and other civil engineering structures, since it allows high load carrying capacity and long service life. In general, Swedish road and rail tunnels should be designed for a service life of 120 years. LÄS MER
2. Above Ground Durability of Swedish Softwood
Sammanfattning : This thesis describes aspects of durability of Swedish softwood in above ground applications. The thesis consists of a summary of nine papers, which all aim to explain the existing variation in above ground microbial durability and moisture sensitivity of Norway spruce (Picea abies) and Scots pine (Pinus sylvestris).

3. Hygrothermal Durability of Adhesively Bonded FRP/steel Joints
Sammanfattning : Fibre reinforced polymer (FRP) composites offer superior mechanical properties, such as specific strength and stiffness, corrosion resistance and light weight. Over the past four dec-ades, FRPs have been increasingly used for strengthening and repair of bridge structures, and more recently, in the manufacture of whole/hybrid FRP bridges. LÄS MER
4. Durability of Reinforced Concrete under Impressed Current Cathodic Protection
Sammanfattning : Impressed current cathodic protection (ICCP) and prevention (ICCPre) are reliable and efficient techniques to stop, control and postpone corrosion in reinforced concrete structures. However, the wide application of this technique has been limited by the high cost of the anode system. LÄS MER
5. Usability of Textile Reinforced Concrete: Structural Performance, Durability and Sustainability
Sammanfattning : Textile reinforced concrete (TRC) is an innovative high performance composite material consisting of open multi-axial textiles embedded in a fine-grained concrete matrix. Despite the fact that TRC-based research has revealed many promising attributes, it has yet to reach its recognition due to a lack of available design tools, standards and long-term behaviour. LÄS MER
