1. 1. Grundisolering för flerbostadshus : Jämförelse av cellglas och cellplast avseende energieffektivisering, ekonomiska aspekter och miljöpåverkan

   Uppsats för yrkesexamina på grundnivå, Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

   Författare :Samir Akhras; Mustafa Arab; Ahmed Yasin; [2023]
   Nyckelord :Thermal insulation; cellular glass insulation; expanded polystyrene insulation EPS ; extruded polystyrene insulation XPS ; energy balance; moisture; specific heat losses and life cycle analysis.;

   Sammanfattning : Purpose: This project compares two foundation insulation materials: cellular plastic and cellular glass. Currently, cellular plastic is the most used material for foundation insulation. While cellular glass is not widely utilized. Its disadvantage lies in its higher cost, which makes contractors prefer the cheaper alternative, cellular plastic. LÄS MER

3. 2. Phase Change Material : Potential for increased fire resistance in concrete

   Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Författare :William Toivanen; [2023]
   Nyckelord :Phase change material; concrete; fire resistance; integration into building materials; latent heat; melting;

   Sammanfattning : The European commission has in the Energy Performance of Buildings Directive from 2010 decided that its member states were required to ensure that all new buildings by the end of 2020 were nearly zero-energy buildings. These buildings require small amounts of energy compared to its performance in example by keeping a pleasant indoor climate. LÄS MER

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

   Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Författare :Felix Hansen; Mathias Berglund; [2023]
   Nyckelord :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.;

   Sammanfattning : 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. LÄS MER

5. 4. En funktion- och miljöpåverkansanalys av isolerande lättfyllnadsmaterial. : En jämförande studie av cellplast, mineralull, lättklinker, skumglas samt isobetong som isolerande skikt i platta på mark.

   Uppsats för yrkesexamina på grundnivå, Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet

   Författare :Melker Iversen; Josef Lebedev; [2023]
   Nyckelord :Foundation; Thermal insulation; Life Cycle Analysis; Environmental impact; GWP; Slab on ground.; Grundläggning; Värmeisolering; Livscykelanalys; Miljöpåverkan; GWP; Platta på mark.;

   Sammanfattning : This study discusses the current state of climate change, which is causing rising sea levels, increasing temperatures, and threatening ecosystems due to human resource exploitation and carbon emissions. The construction industry is a significant contributor to greenhouse gas emissions, and the study aims to investigate which insulation material is best suited for a ground slab in terms of environmental impact, technical properties, and cost.

7. 5. Experimental and computational analysis of the thermal degradation and the loss of strength of engineered wood-based panels

   Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

   Författare :Wickramasooriyage Devmini Kularatne; [2022]
   Nyckelord :Oriented strand board; thermal decomposition; mechanical degradation; heat transfer modelling; Technology and Engineering;

   Sammanfattning : The current trends in the construction industry push toward materials that are more sustainable and environmentally friendlier than more traditional building materials such as concrete and steel. Timber and timber composites are one of the most popular materials on this list, due to both their mechanical strength and pleasant aesthetics. LÄS MER
