2. 1. Durability of fire exposed concrete : Experimental Studies Focusing on Sti„ffness & Transport Properties

   Author : Joakim Albrektsson; Johan Silfwerbrand; Lars Boström; Manouchehr Hassanzadeh; KTH; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Concrete; Fire; Polypropylene fibres; Durability; Tunnel; Damage assessment; Ultrasonic pulse velocity; Water absorption; Chloride migration; DIC; Byggvetenskap; Civil and Architectural Engineering;

   Abstract : 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. READ MORE

4. 2. Above Ground Durability of Swedish Softwood

   Author : Åsa Blom; Mikael Bergström; Thomas Thörnqvist; Birger Eikenes; Växjö universitet; []
   Keywords : above ground; durability; field test; mass loss; Mycologg; Norway spruce; permeability; Picea abies; Pinus sylvestris; Scots pine; FORESTRY; AGRICULTURAL SCIENCES and LANDSCAPE PLANNING; SKOGS- och JORDBRUKSVETENSKAP samt LANDSKAPSPLANERING;

   Abstract : 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).

5. 3. Hygrothermal Durability of Adhesively Bonded FRP/steel Joints

   Author : Mohsen Heshmati; Chalmers University of Technology; []
   Keywords : TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; cohesive zone modelling; durability; moisture diffusion; Fibre reinforced polymer; adhesively bonded FRP steel joints; long-term performance;

   Abstract : 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. READ MORE

6. 4. Durability of Reinforced Concrete under Impressed Current Cathodic Protection

   Author : Emma Zhang; Chalmers University of Technology; []
   Keywords : TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; durability; cathodic protection and prevention; anode system; service life; critical chloride content; Chloride initiated corrosion;

   Abstract : 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. READ MORE

7. 5. Usability of Textile Reinforced Concrete: Structural Performance, Durability and Sustainability

   Author : Natalie Williams Portal; Chalmers University of Technology; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sustainability; life cycle assessment; experimental methods; finite element analysis; durability; Textile reinforced concrete;

   Abstract : 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.
