  1. 1. Laboratory testing of shotcrete with fibres of steel, basalt or synthetic materials

    University essay from KTH/Betongbyggnad

    Author : Muralidharan Rengarajan; [2020]
    Keywords : Fibre reinforced shotcrete; Energy absorption; Residual strength; Fibres; and Laboratory testing;

    Abstract : Shotcrete or sprayed concrete has become an inevitable material for stabilising and supporting hard rock tunnels. To prevent rock block fallouts in the excavated tunnel, shotcrete is pneumatically projected under high pressure on the rock surface. READ MORE

  2. 2. Numerical Assessment of Defects Effect on Boltless Composites Longitudinal Joints

    University essay from KTH/Lättkonstruktioner

    Author : Mara Santaniello; [2020]
    Keywords : ;

    Abstract : The work presented in this thesis focuses on the numerical assessment of defects effect on potential boltless design for fuselage panels longitudinal joints, typically identified as High Load Transfer (HLT) configuration. Nowadays, the state-of-art joining technique for primary aircraft composite structures, such as fuselage barrels, is still mechanical fastening. READ MORE

  3. 3. Keen for Green - A Study of Pricing in the Secondary Green Bond Market

    University essay from Lunds universitet/Företagsekonomiska institutionen

    Author : Rickard Anderkrans; Patrik Johannesson; [2019]
    Keywords : Green bonds; Panel data; Issuer fixed effects regression; Capital asset pricing model; Investor preference; Business and Economics;

    Abstract : The emerging green bond market is a novel research area with only a few studies being published in recent years. The increase in interest from issuers, investors, and academia shows the clear need for further investigation of the pricing dynamics affecting the green bond market. READ MORE

  4. 4. Topology-guided analysis and visualization of charge density fields

    University essay from Linköpings universitet/Institutionen för fysik, kemi och biologiLinköpings universitet/Tekniska fakulteten

    Author : Elvis Jakobsson; [2019]
    Keywords : Visualization; Topology; Charge density; Direct Volume Rendering; Crystal structure;

    Abstract : Direct volume rendering techniques for scalar fields make use of transfer functions to map optical properties to the field; the field can subsequently be visualized through the drawing of isosurfaces in the volume spanned by the field. The utility of this approach is limited in the case of nested or clustered structures with the same isovalue and further does not easily allow for quantitative measurements of the visualized data.

  5. 5. Design of Ultra High Performance Fibre Reinforced Concrete Bridges : A Comparative Study to Conventional Concrete Bridges

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Viktor Eriksson; [2019]
    Keywords : Bridge design; CO2 emissions; Mechanical properties and behaviour; Straight short steel fibres; UHPC; UHPFRC; Bro dimensionering; CO2 utsläpp; Korta raka stålfibrer; Mekaniska egenskaper och beteende; UHPC; UHPFRC;

    Abstract : The use of Ultra High Performance Fibre Reinforced Concrete (UHPFRC) in the construction industry started in the 1990s and has since then been used for bridges all over the world. The mechanical properties and the dense matrix result in lower material usage and superior durability compared to conventional concrete, but the implementation of UHPFRC in the Swedish industry has been delayed.
