  2. 1. Life Cycle Assessment of Building Products. Case Studies and Methodology

    Author : Åsa Jönsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VOCs; environmental assessment; floorings; methods; LCA; concrete; indoor climate; Life Cycle Assessment; structural frames; building materials; steel; tools;

    Abstract : The main objectives of this thesis were to demonstrate how Life Cycle Assessment (LCA) may be applied to building products, to describe what methodological LCA issues are specific to building products, to work out solutions to some of these issues and to relate LCA to other environmental assessment methods that may be applied to building products. First, in a literature study, the state of the art in the field of environmental assessment of building products is described, and the five articles constituting the thesis are put into context.

  4. 2. The role of biobased building materials in the climate impacts of construction : Effects of increased use of biobased materials in the Swedish building sector

    Author : Diego Peñaloza; Magnus Wålinder; Martin Erlandsson; Andreas Falk; Johanna Berlin; Dimitris Athanassiadis; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LCA; timber buildings; timber bridges; biobased building materials; dynamic LCA; climate change mitigation; building stock; scenario analysis; biogenic carbon; Byggvetenskap; Civil and Architectural Engineering;

    Abstract : A significant share of the global climate change impacts can be attributed to the construction sector. One mitigation strategy is increasing the use of biobased materials. Life cycle assessment (LCA) has been used to demonstrate the benefits of this, but forest complexities create uncertainty due to omission of key aspects. READ MORE

  5. 3. Sustainability and Flexural Behaviour of Textile Reinforced Concrete

    Author : Natalie Williams Portal; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Life Cycle Assessment LCA ; sustainability; Textile Reinforced Concrete; TRC; facade elements; flexural behaviour; non-linear finite element analyses; structural tests;

    Abstract : Concrete reinforced with conventional steel is one of the most commonly used building materials, yet it has historically shown disadvantages in terms of durability and vulnerability to corrosion attack. Various remedial methods have been applied to overcome the shortcomings of this building material, such as increasing the concrete cover, which, however, leads to an increased self-weight of the structure.

  6. 4. A Life Cycle Approach to Environmental Sustainability in Aggregate Production Systems

    Author : Christina Lee; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Aggregates; Gravel; Sand; LCA; Production Systems; Sustainability; Life Cycle Assessment; Environmental Management; EPDs; Quarries; Tool Development; Environmental Impact; Environmental Product Declarations; Construction Products;

    Abstract : Rock materials, such as sand, gravel, and crushed rock, serve as the foundation of our society. Known collectively as aggregates, these materials are essential for building foundations, concrete, and roads, making them the second most extracted material globally after water. READ MORE

  7. 5. Fibre reinforced polymer bridge decks: Sustainability and a novel panel-level connection

    Author : Valbona Mara; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bridge; Sustainability; LCA; Life-cycle assessment; FRP deck; LCC; Life-cycle cost; Connection;

    Abstract : Fibre reinforced polymer (FRP) bridge decks have emerged as a competitive alternative to traditional decking solutions for the refurbishment of existing bridges, as well as the construction of new ones, in the past two decades. FRP decks offer inherent properties such as light weight, high strength and high resistance to aggressive environments. READ MORE
