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 : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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. Material properties related to fire spalling of concrete

   Author : Robert Jansson; Avdelningen för Byggnadsmaterial; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Concrete; thermal properties; fire spalling; polypropylene fibres;

   Abstract : Despite almost 100 years of research, the fundamentals of fire spalling of concrete are not yet fully understood. Many different theories exist, each trying to describe the coupling between different phenomenon leading to fire spalling. Some of these phenomenon have been investigated and are presented in this thesis. READ MORE

5. 3. Fire Spalling of Concrete : Theoretical and Experimental Studies

   Author : Robert Jansson; Johan Silfwerbrand; Ulrich Diedrichs; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Fire spalling of concrete is not a new phenomenon. To some degree there has always been a risk during rapid heating of concrete. Therefore, to a certain degree the effect of fire spalling is included in the bank of data from fire tests and fires on which our understanding of the fire resistance of concrete is based. READ MORE

6. 4. Fire temperature development in enclosures : Some theoretical and experimental studies

   Author : Alexandra Byström; Björn Karlsson; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad;

   Abstract : This thesis is devoted to problems connected to heat transfer and fire dynamics in enclosures. The thesis consists of a main part which summarizes and discusses the theory of heat transfer, conservation of energy and fire dynamics. Based on these theories, some cases of different fire scenarios have been analyzed. READ MORE

7. 5. Framing Technological Development in a Concrete Context : The Use of Wood in the Swedish Construction Industry

   Author : Anna Bengtson; Håkan Håkansson; Alexandra Waluszewski; Poul Rind Christensen; Uppsala universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Business studies; technological development; context; industrial networks; construction industry; Företagsekonomi; Business studies; Företagsekonomi; nationalekonomi; Economics;

   Abstract : An understanding of the factors that condition technological development is of vital importance for business theory as well as for practitioners. The contextual setting of the development constitutes one area of inquiry into this research field. READ MORE
