  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. Improving Availability of the Pelletization Process

    University essay from Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

    Author : Emil Andreasson; Pontus Åhman; [2022]
    Keywords : Availability; Predictive Maintenance; Pelletization; Statistical Process Control; Refractory Material; DMAIC;

    Abstract : The Grate-Kiln-Cooler process is a commonly used method of sintering during iron ore pelletization, where the pellets are formed, dried, and hardened. The pellets are oxidized in the rotating Kiln, turning magnetite (Fe3O4) to hematite (Fe2O3), making the pellets attain suitable metallurgical attributes for further processing. READ MORE

  4. 3. ADDITIVE MANUFACTURING OF PURE COPPER USING ELECTRON BEAM MELTING (EBM)

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Prithiv Kumar Chinnappan; Vishal Shanmugam; [2022]
    Keywords : Additive Manufacturing; Electron Beam Melting; Pure Copper; Process Optimisation.; Additiv tillverkning; Elektronstrålesmältning; Ren koppar; Processoptimering.;

    Abstract : Pure copper (Cu) has the properties of high optical reflectivity and surface tarnishing as well as excellent thermal and electrical conductivity. Accordingly, laser-based additive manufacturing (AM) techniques confront various difficulties to produce thismaterial. READ MORE

  5. 4. Optimization and Characterization of Luminescent Materials for the ESS Proton Beam Imaging System

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Emelie Wiklund; Anton Järild; [2021]
    Keywords : Chemical Engineering; Luminescent materials; Cr-doped Alumina; Proton Beam Imaging System; ESS; Chemistry; Technology and Engineering;

    Abstract : Spallation sources such as European Spallation Source (ESS) produces neutrons by bombarding high-energy protons onto the target wheel. To determine the location of the proton beam a Proton Beam Imaging (PBI) system will be installed. READ MORE
