  2. 11. Frost-induced deterioration of concrete in hydraulic structures : Interactions between water absorption, leaching and frost action

    Author : MARTIN ROSENQVIST; Avdelningen för Byggnadsmaterial; []
    Keywords : Vattenbyggnader; Dammar; Betong; Cement; Vattenabsorption; Vattenmättnadsgrad; Nedbrytning; Frostbeständighet; Spjälkning; Makroskopisk islinsbildning; Urlakning; Synergi; Hydraulic structures; Dams; Concrete; Cement; Water absorption; Degree of saturation; Deterioration; Frost resistance; Spalling; Macroscopic ice lens growth; Leaching; Synergy;

    Abstract : Frost deterioration of concrete can result in severe consequences to the safety, durability and functionality of a structure since it impairs the strength of the concrete. Frost damage may occur to structures that are in contact with water and subjected to frost action. READ MORE

  5. 13. Leaching, filtration and displacement washing in a treatment process for MSW combustion fly ash - laboratory scale and plant studies

    Author : Magda Wilewska-Bien; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; washing; filtration; MSW; cyclone ash; : leaching; fly ash; MSWI ash;

    Abstract : Municipal Solid Waste combustion, as one of the waste management tools, starts to play an important role nowadays in heat and energy generation. However, MSW combustion leads to generation of other wastes - combustion residues, including ashes, which require a proper management. READ MORE

  7. 15. Metals in MSWI fly ash - problems or opportunities?

    Author : Karin Karlfeldt Fedje; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HNO3; water; NH3NO4; MSW ash; pH; metals; solvent extraction; speciation; Cu; leaching;

    Abstract : Incineration of municipal solid waste is a commonly used management method to take care of our waste. However, the residues produced are a problem. They often contain large amounts of potentially toxic metal compounds and soluble salts, which can cause harm to the environment and human health if released from the ash. READ MORE
