    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

  4. 8. Use of Polyvinyl chloride (PVC) as an aggregate for concrete

    Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Habib Loubani; [2023]
    Nyckelord :Polyvinyl chloride; PVC aggregates; natural aggregate concrete; PVC fine aggregates concrete; PVC coarse aggregates concrete;

    Sammanfattning : This study investigates the use of polyvinyl chloride (PVC) as a partial substitute of natural aggregates in concrete as fine and coarse aggregates. Concrete was prepared by replacing natural aggregates with equal volume of grinded PVC, with volume replacement ratio as 10%, 50% for fine and then 10% and 50% for coarse aggregates. LÄS MER

  5. 9. 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. 10. Framtagning av klimatsmart betong för 3D-skrivning

    Kandidat-uppsats, KTH/Byggteknik och design

    Författare :Maryoo Mate; Aden Ibrahim; [2022]
    Nyckelord :;

    Sammanfattning : 3D-printing was originally created for use in prototype manufacturing. It has been developed and adapted for use in a variety of sectors. Now this technology has the chance to revolutionize another sector, namely the construction sector. One problem with 3D writing is small nozzles that limit the size of the aggregate particles. LÄS MER
