  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. Towards low carbon buildings: A case study in Sweden

    University essay from Lunds universitet/Avdelningen för Energi och byggnadsdesign; Lunds universitet/Institutionen för arkitektur och byggd miljö

    Author : Huynh Tuan Tran; Victor-Antoine Delorme; [2023]
    Keywords : Life cycle assessment; Environmental impact of building materials; Carbon neutrality; Biobased material; Biochar; Cross Laminated Timber; Biogenic carbon; Earth and Environmental Sciences; Technology and Engineering;

    Abstract : This study comprehensively evaluated the global warming potential of an office building in a newly built Scandinavian neighbourhood seeking to reach sustainability. The primary objective of the research was to support the city authorities of Helsingborg by providing valuable insights into actual carbon emissions at the building level and proposing measures to minimize these emissions to achieve climate neutrality by 2030.

  4. 3. The effect of high-ratio biochar replacement in concrete on performance properties : Experimental study of biochar addition to concrete mixture.

    University essay from Luleå tekniska universitet/Byggkonstruktion och brand

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

    Abstract : 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.

  5. 4. Biochar-based thin-layer capping of contaminated sediment in Burefjärden, northern Sweden : Assessment of biochar mixed into four structural materials for preventing release of trace elements from sediment to water

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

    Author : Nathalie Pantzare; [2021]
    Keywords : biochar; contaminated sediment; remediation; thin-layer capping;

    Abstract : Coastal areas around the world have been recognized as largely impacted by anthropogenic activities resulting in pollution of marine sediments. In Sweden, surveys conducted along the coastline of the Bothnian Bay have identified a total area of about 29 km2 as fiber rich sediments. READ MORE

  6. 5. Carbon Stability of Biochar : Methods for assessment and indication

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Helena Söderqvist; [2019]
    Keywords : Biochar; Stability; MRT; Carbon sink; Carbon stability; Negative emissions technology NET ;

    Abstract : Biochar can reduce the amount of CO2 in the atmosphere and is acknowledged as one feasible technology for negative carbon emissions. The stability of carbon in biochar is of major importance for the carbon sequestration value. A method for confident estimation of the stability is needed to make efficient priorities for the climate. READ MORE
