   University essay from KTH/Betongbyggnad

   Author : John Abdalnour; Milad Saliba; [2023]
   Keywords : ;

   Abstract : This master's thesis aimed to investigate the behaviour of reinforced concrete beams under dynamic loading conditions, specifically focusing on understanding shear failure. The study was conducted with KTH Royal Institute of Technology, the Swedish Fortifications Agency, and Tyréns. READ MORE

3. 2. The Effect of Chloride-Induced Corrosion Patterns on the Crack Width of Reinforced Concrete

   University essay from KTH/Betongbyggnad

   Author : Dilara Uludag; [2023]
   Keywords : ;

   Abstract : This master's thesis investigates cracking in a parking garage, with a particular focus on the influence of corrosion. Concrete structures commonly experience cracking, and corrosion has emerged as one of the primary contributing factors. These cracks, varying in size and shape, can be considered structural discontinuities. READ MORE

4. 3. The Effect on Mechanical Properties in Biochar Replaced Cement & Aggregate in Concrete Before and After Fire Exposure

   University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Author : Felix Hansen; Mathias Berglund; [2023]
   Keywords : Biochar; Concrete; Sintering; Fire; Mechanical properties; Sustainability; Cement; Biochar in concrete; Building industry; Concrete exposed to fire.; Biokol; Betong; Sintring; Eld; Mekaniska egenskaper; Hållbarhet; Cement; Biokol i betong; Byggindustri; Brandexponerad betong.;

   Abstract : Concrete is good as a construction material regarding fire and its properties regarding strength. However, the concrete expands and cracks due to fire resulting in structural damage. According to the literature the concrete usually loses its strength during and after fire exposure due to themechanical and physical changes. READ MORE
