1. 1. 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

3. 2. Determination of thermal conductivity for mastic asphalt by combining previously performed laboratory work and TASEF

   University essay from Luleå tekniska universitet/Byggkonstruktion och brand

   Author : Martin Kruse Lindgren; [2021]
   Keywords : Mastic asphalt; BPGJA-11; thermal conductivity; TASEF; FEM; Timber; Gjutasfalt; BPGJA-11; termisk konduktivitet; TASEF; FEM; Trä;

   Abstract : Mastic asphalt is a material which in Sweden mainly is used as coating for bridges, parking decks, courtyards and terraces. Mastic asphalt is a material built-up by a combination of bitumen (a type of binder), well-graded aggregate (consists of both coarse and fine ballast), filler, sand and sometimes also fine graded macadam.

4. 3. Temperature analysis of fire exposed load-bearing structures of mono glazed balconies

   University essay from Luleå tekniska universitet/Byggkonstruktion och brand

   Author : Andreas Lilja; [2020]
   Keywords : CFD; FDS; FEM; TASEF; EKS; Eurocode; Simulation; Fire; Balcony; CFD; FDS; FEM; TASEF; EKS; Eurokoderna; Simulering; Brand; Balkong;

   Abstract : Previous to the now acting construction regulations EKS and Eurocode, the fire resistance of the load-bearing structures of mono glazed balconies were designed with a fire test called the SP fire 105. In 2011, when EKS replaced the previous construction regulations called Boverkets konstruktionsregler, BKR, the SP fire 105 was no longer the requirement for mono glazed balconies. READ MORE

5. 4. Experimental Fire Study of Expanded Polystyrene Insulation in Concrete and Lightweight Concrete Wall Constructions

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

   Author : Jacob Nellgård; [2017]
   Keywords : EPS; Expanded Polystyrene; Concrete; Lightweight Concrete; Vertical Firespread;

   Abstract : In today’s building industry creating and finding a cheaper and more efficient way of construction with the same standards is the primary goal. The necessity in testing the constructions in different scenarios is of highest interest, primarily in saving future lives but also in the residual value for the insurance point of view. READ MORE

6. 5. Structural assement and design of concrete structures under fire conditions

   University essay from KTH/Betongbyggnad

   Author : Pierre Legrand; [2016]
   Keywords : Fire; concrete; elevated temperature;

   Abstract : Behaviour under fire circumstances is becoming more and more crucial for designing a concrete structureand authorities require more often a fire-resistance time. In fact, engineers need a powerful, user-friendly,accurate and non time-consuming method that can be used to design reinforced concrete structures. READ MORE
