  1. 1. Study of permanent formwork made of high-performance concrete as protection of concrete with recycled aggregate

    University essay from KTH/Betongbyggnad

    Author : Eliška Kafková; [2022]
    Keywords : Fiber-reinforced concrete; textile-reinforced concrete; high-performance concrete; concrete with recycled aggregate; fiber reinforcement; textile reinforcement; carbon footprint;

    Abstract : The production of concrete remains one of the highest CO2 producers. It consumes alarge number of primary sources of raw materials. One way to reduce emissions and rawmaterials consumption is by applying more recycled aggregates. READ MORE

  3. 2. XAI-assisted Radio Resource Management: Feature selection and SHAP enhancement

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Nicolás Sibuet Ruiz; [2022]
    Keywords : Deep Learning; Explainable Artficial Intelligence; 5G; Model Reduction; Deep Learning; Förklarlig AI; 5G; Modellreduktion;

    Abstract : With the fast development of radio technologies, wireless systems have become more convoluted. This complexity, accompanied by an increase of the number of connections, is translated into a need for more parameters to analyse and decisions to take at each instant. READ MORE

  4. 3. Dynamic Performance of a Tall Building to Earthquake Loading : Finding the optimum mass and stiffness

    University essay from KTH/Bro- och stålbyggnad

    Author : Andrés Alonso San Segundo; [2022]
    Keywords : ;

    Abstract : With the increasing cost of land, the development of ultra-high performance concrete, and the technological advancements in equipment and machinery, we are able to construct and refurbish skyscrapers like never before. How they are built, what materials they use, or what structural system defines them, all affect their dynamic response, which in the end is the combination of the stiffness and mass, two key parameters in engineering of tall buildings.

  5. 4. 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.
