1. Karbonatisering av riven betong
Uppsats för yrkesexamina på grundnivå, Uppsala universitet/MikrosystemteknikSammanfattning : This study investigates the carbonation process in concrete, where carbon dioxide is naturally absorbed by the concrete over time. Crushing the concrete into smaller fractions has the potential to accelerate this process. LÄS MER
2. Accelerated Carbonation Of Cement Pastes And Mortars
Kandidat-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomiSammanfattning : Concrete structures have the largest surface area of all human made structures. Large surface area makes concrete capable to absorb CO2 from environment during its lifetime. It is estimated that concrete during its lifetime can absorb about 15-20% of CO2 which had produced in cement production. LÄS MER
3. The Effect of Citric Acid on Amorphous Calcium Carbonate, Mesoporous Magnesium Carbonate and Calcium Magnesium Composite : A brief study
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Nanoteknologi och funktionella materialSammanfattning : During the past decades, emission of greenhouse gases has accelerated to unsustainable levels. This is a serious issue that can have a devastating impact on everything from global economy to the terrestrial or marine ecosystem. A method for reducing the emission is named carbon capture and storage, which this project is based on. LÄS MER
4. Concrete reinforced with FRP rebars : Evaluation of durability and behaviour in the Service Limit State (SLS)
Master-uppsats, Luleå tekniska universitet/Byggkonstruktion och brandSammanfattning : One of the most common building materials is concrete and it has been for a long time. To overcome its low tensile capacity concrete structures are normally reinforced with steel rebars. LÄS MER
5. Koldioxidupptag i betong : Accelererade laboratorieförsök
Master-uppsats, KTH/BetongbyggnadSammanfattning : Concrete absorbs carbon dioxide from air by a process called carbonation. The process takes a long time to get substantial results in natural conditions. Because of this an accelerated carbonation method is used. During accelerated carbonation the level of carbon dioxide is much higher than in natural air. LÄS MER
