1. 1. 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

3. 2. Fibre volume fractions’ and printing directions’ effects on tribological and mechanical properties in FDM printed carbon fibre reinforced PEEK : Suitability assessment of FDM printed PEEK-CF to act in a steam engine’s ball joint, by analysis of compressive properties, impact strength, friction and wear

   University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

   Author : William Tönnberg; [2022]
   Keywords : Ranotor; steam engine; PEEK; polyether-ether-ketone; carbon fibre reinforced PEEK; impact strength; compressive strength; compressive modulus; friction; wear; tribology; FFF; FDM; 3D-printing; printing parameters;

   Abstract : The purpose with this study was to investigate FDM/FFF manufactured carbon fibre reinforced PEEK and assess its suitability to act as a sealing- and bearing material in a modern steam engine’s ball joint. The steam engine is totally free from oil due to the risk of water- and steam contamination. READ MORE

4. 3. Optimization of support in rock pillars between two parallel tunnels

   University essay from KTH/Jord- och bergmekanik

   Author : Alexander Kote; Sohaib Ishaq; [2022]
   Keywords : tunnel; rock pillar support; rock pillar stability; rock mass; stresses; arching effect; Nyckelord: tunnel; bergförstärkning; bergpelare; bergmassa; spänningar; valveffekt;

   Abstract : When two parallel tunnels are excavated under high to moderate horizontal in-situ stresses combined with minor deformations in the pillar between the tunnels, the in-situ stresses can be redistributed over the tunnels in form of two compressive arches and are transferred from the roof to the abutments of the two tunnels. At additional deformations in the pillar, a new redistribution of the stresses can occur creating one compressive arch over both of the tunnels. READ MORE

5. 4. Simulation of load capacity of 3D printed concrete patterns

   University essay from KTH/Betongbyggnad

   Author : Magnus Burton; Karolina Näsén; [2022]
   Keywords : ;

   Abstract : Three-dimensional concrete printing (3DCP) is a technology which has rapidly developed in recent years. The technology is based on a layer-by-layer technique where models are designed in a 3D software program and printed by a robot. Unlike conventional concrete, 3DCP has stricter material requirements due to the absence of formwork. READ MORE

6. 5. Geomechanical testing of non-hardening grout : for determination of flowability and strength properties

   University essay from Luleå tekniska universitet/Geoteknologi

   Author : Axel Barrdahl; [2022]
   Keywords : Non-hardening; Grout; Embankment dam; Repair; Fall cone; Uniaxial Compressive Strength; UCS; Triaxial;

   Abstract : Due to an increasing amount of aging tendencies in Swedish embankment dams, failures such as internal erosion has become a more common problem. Internal erosion is a phenomenon where certain soil material within the embankment dam is removed, often over a longer period of time. READ MORE
