1. 1. Effects of Steel Fibres on Cracking in Reinforced Concrete

   Författare :Anette M Jansson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; uniaxial tension test; Keywords: Self-compacting; characteristic crack width; fibre-reinforced; bond; tension stiffening; Digital Image Correlation; pull-out test;

   Sammanfattning : ABSTRACTAlthough it is well known that fibre reinforcement acts as a crack arresting agent, there is still a need for deeper knowledge of the actual cracking behaviour, especially regarding cracks with widths smaller than 0.3mm. LÄS MER

3. 2. Fibre-reinforced Concrete for Industrial Construction - a fracture mechanics approach to material testing and structural analysis

   Författare :Ingemar Lövgren; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; in-situ cast; non-linear; self-compacting; fibre-reinforced; concrete;

   Sammanfattning : ABSTRACTMore efficient and industrialised construction methods are both necessary for thecompetitiveness of in-situ concrete and essential if the construction industry is to moveforward. At present, the expenditure on labour (preparation and dismantling offormwork, reinforcing, and casting and finishing of concrete) almost equals the cost ofmaterial. LÄS MER

4. 3. Tensile behaviour of mineral-based composites

   Författare :Katalin Orosz; Anders Ansell; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

   Sammanfattning : Externally bonded fibre-reinforced polymer (FRP) systems have shown to be a robust and durable way to repair, or strengthen concrete structures. Epoxy, as the most common bonding agent, provides excellent force transfer, and bonds well to the base substrate to the as well as to the strengthening material. LÄS MER
