  1. 1. Moisture and Chloride Transport in Concrete

    Author : Filip Nilenius; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multiscale modelling; mass transport; coupled diffusion; statistical volume element; interfacial transition zone.; computational homogenization; mesoscale;

    Abstract : Material properties pertaining to the physical phenomena of mass transport in concrete are important for the durability of concrete structures, and they can ultimately be derived from material heterogeneities found at different subscales. On the mesoscale level, these heterogeneities are mainly characterized by the presence of embedded aggregates in the cement paste, together with cracks. READ MORE

    Abstract : The work presented in this thesis is mainly focused on transport processes involved in service life predictions of concrete. Two papers and three reports deal with ion transport in pore solution of concrete. READ MORE

  3. 3. Natural corrosion in reinforced concrete structures

    Author : Samanta Robuschi; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Natural corrosion; pitting corrosion; reinforced concrete structures; chloride-induced corrosion.; neutron imaging; anchorage; plain bars; X-rays CT;

    Abstract : Among the threats to the durability of concrete structures, corrosion of the reinforcement bars is undoubtedly the most common one. Corrosion damages impair safety and durability of infrastructure, and assessment of the safety is challenging due to the complex nature of the corrosion process. READ MORE

  4. 4. Multi-scale modeling and finite element simulation of diffusion in porous media

    Author : Nele Pollmann; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydro-Mechanical Coupling; Fractured Rock; Poroelasticity; Three-Phase Concrete; Computational Homogenization;

    Abstract : Porous media comprise a large range of natural and industrial materials and are typically complex on multiple length scales. At lower (micro-scopic) length scales, such media consist of a solid skeleton and fluid-filled pores in between. READ MORE
