3. 2. 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

4. 3. Analyzing components of barrier coatings in different fractions during a repulping process.

   University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

   Author : Evelina Särnholm; [2021]
   Keywords : ICP-MS; MP-AES; GC-MS; repulping process; paper; poly ethylene-co-acrylic acid ;

   Abstract : During paper manufacturing, coating and adhesives are added to paper and cardboard to improve quality and durability. When the paper is later recycled or becoming new paper, the coatings may pollute the water used in the recycling process. Thus, it is important to know in which fraction these coatings finish during the process. READ MORE

6. 5. Evaluation of alternative methods forquality control of Tungsten Carbide : An evaluation of four different particle measuring techniques

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

   Author : Markus Näsman; [2019]
   Keywords : Particle measurement; Quality control; Tungsten Carbide; Hard metal; Fisher Sub-Sieve Sizer; Brunauer Emmett Teller; X-ray Diffraction; Laser Diffraction;

   Abstract : The purpose of this study was to evaluate four different measuring methods as potentialquality control tests for Tungsten Carbide (WC) raw material used in the hard metalmanufacturing at Seco Tools Fagersta. This was warranted as the current quality testcalled the HcK test, is very time consuming and the results provided that are used formilling time calculations cannot be relied on. READ MORE
