  3. 2. Permanent Fire Load of the Building Envelope

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Gizelle Danine Pondevida Jamero; [2023]
    Keywords : Permanent fire load; temporary fire load; fire load; building envelope; insulation; building content; upholstered furniture; heat of combustion; MCC; bomb calorimeter; cone calorimeter; room corner test.; Technology and Engineering;

    Abstract : Fire load, the total thermal energy released by the combustion of a material, is an essential part of determining a building’s fire performance and the associated fire protection strategies. Elements in a structure are typically categorized into two types of fire loads: permanent and temporary. READ MORE

  4. 3. 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

  5. 4. Swedish “tofu” from faba beans : a textural and structural analysis

    University essay from SLU/Department of Molecular Sciences

    Author : Saga Preis; [2023]
    Keywords : Tofu; faba bean; Vicia faba; texture; microstructure;

    Abstract : Tofu, a traditional soybean product, is a popular plant-based alternative which could potentially be produced from Swedish-grown faba beans (Vicia faba L.). The aim of this project was to asses the viability of producing a tofu-like faba bean product using food grade gypsum (calcium sulphate) as coagulant. READ MORE
