  1. 1. EVALUATION OF ENVIRONMENTAL AND TECHNICAL PERFORMANCE OF ALTERNATE FIBRES FOR SHOTCRETE IN TUNNELS

    University essay from KTH/Betongbyggnad

    Author : Shilpa Anand; [2022]
    Keywords : Shotcrete; Life cycle assessment; Environmental Product Declaration; Global warming potential; steel; basalt and synthetic fibres; flexural strength; energy absorption.;

    Abstract : Tunnels in hard and jointed rock are normally excavated in an arch shape to enable the rock mass to support its weight. Since the beginning of the 1980's, fibre reinforced shotcrete (FRS) in combination with rock bolts have been the dominating support method for hard rock tunnels. READ MORE

  2. 2. Characterization methodology to assess the mechanical properties of delignified birch/PMMA transparent wood biocomposites

    University essay from KTH/Fiber- och polymerteknologi

  3. 3. The Correlation of Workability and Mechanical Strength in air lime binders with different aggregates and pozzolan

    University essay from Göteborgs universitet/Institutionen för kulturvård

    Author : Natalia Ioanna Dedousi; [2021-03-16]
    Keywords : conservation; air-limes; binders; aggregates; pozzolan;

    Abstract : In this study are investigated two air lime binders common in conservation practice. The first one is a commercial air lime, emerging from dry slaking, which was left to age for 4 months. The second is a natural quicklime emerging from the burning in a traditional lime kiln from Mariestad, Sweden. READ MORE

  4. 4. Infrared Curing of Glass Fiber Composite Tube : Optimization of the curing cycle

    University essay from Karlstads universitet/Avdelningen för maskin- och materialteknik

    Author : Rasmus Fredheim; [2021]
    Keywords : ;

    Abstract : This thesis has investigated the possibility of optimizing curing time by changing the energy source from a conventional oven to infrared radiation (IR) and if it is possible to achieve similar results as the company's current production of glass fiber composite tubes.   Many different parameters (time, temperature, heating rate, and rotation speed) might influence a cured composite tube's properties.
