  1. 1. Quality Assurance of Recycled HDPE in the Plastic Packaging Industry

    Master-uppsats, Lunds universitet/Innovation

    Författare :Tora Abrahamsson; Juliana Kalling; [2023]
    Nyckelord :Thermoforming; Plastics; Recycling; Packaging Industry; HDPE; Technology and Engineering;

    Sammanfattning : The recycling of plastic has the potential to support circular material use, thus decreasing the need for virgin plastics. However, there is an existing issue with assuring quality of recycled plastic materials, causing finished products to perform with poorer properties and unexpected deviations. 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. The effect of high-ratio biochar replacement in concrete on performance properties : Experimental study of biochar addition to concrete mixture.

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Byggkonstruktion och brand

    Författare :Mina Turovaara; [2022]
    Nyckelord :Biochar; Concrete; Sustainability; Cement; Biochar in concrete; Carbon dioxide; Building industry; Micro-structure; Biokol; Betong; Hållbarhet; Cement; Biokol i betong; Koldioxid; Byggsektorn; Mikrostruktur;

    Sammanfattning : Globally the emissions of carbon dioxide from anthropogenic activities are an issue regarding the future of our planet. Today the building industry is a large contributor with approximately 10 percent of the total emissions coming from energy usage in the building industry, where about 7 percent of the global CO2 emissions are connected to the cement industry.

  7. 5. Background Studies of the High-Intensity Baryon Extraction and Measurement (HIBEAM) Experiment at the European Spallation Source

    Master-uppsats, Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

    Författare :Blahoslav Rataj; [2021]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : The High-Intensity Baryon Extraction and Measurement experiment (HIBEAM) is proposed as one of the experimental stations at the European Spallation Source (ESS). This experiment will mainly focus on the neutron into sterile neutron oscillations which violate the baryon number (B) by one unit. LÄS MER
