  1. 1. Optimization of concrete recipe made with crushed aggregate

    University essay from Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet

    Author : Jonathan Lindekrantz; Pontus Axelsson; [2023]
    Keywords : ;

    Abstract : This paper investigate however concrete recipes with a specific type ofcrushed aggregate can be optimized to reduce cement content for concreteand compares it to concrete made with natural fine aggregate. The different aggregate types are sieved, and the particle size distribution curve is made for each one. READ MORE

  3. 2. Possibilities of Reducing Internal Scrap Rates and Increase Scrap Recyclability of Dilute Copper Alloys from Vertical Upwards Continuous Cast (VUCC) Process

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Minna Olsson; [2023]
    Keywords : metallurgy; copper; alloy; continuous casting; materials chemistry; Technology and Engineering;

    Abstract : Copper and copper alloys are important material systems for the electrification of society. The high workability of the materials makes them appropriate in numerous different applications which require highly conductive properties. READ MORE

  4. 3. Användning av krävande ballastmaterial vid betongtillverkning - En laborativ utvärdering av absorptionshämmande tillsatsmedel för att möjliggöra användning av glimmerrik bergkross och återvunnen betong som ballast

    University essay from Lunds universitet/Avdelningen för Byggnadsmaterial

    Author : Anna Hagberg; Andreas Andersson; [2023]
    Keywords : Absorption inhibitor; admixtures; aggregate; biotite; calorimetry; compressive strength; concrete; heat development; mica; recycled concrete; workability; Technology and Engineering;

    Abstract : Detta examensarbete utvärderar ett absorptionshämmande tillsatsmedel för att möjliggöra användningen av krävande ballast vid betongtillverkning. Den huvudsakliga anledningen till att ballasten benämns som krävande är att den har ovanligt hög absorptionsförmåga. READ MORE

  5. 4. 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

  6. 5. Use of Polyvinyl chloride (PVC) as an aggregate for concrete

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

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

    Abstract : 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. READ MORE
