6. DFT calculations of initial localized corrosion of aluminum : Influence of aqueous ad-layer, chloride ions, and intermetallic particles
Sammanfattning : Localized corrosion of aluminum (Al, here including Al alloys) involves a series of physico-chemical processes at the interface between the metal and the aqueous ad-layer or the aqueous solution. The mechanisms that govern localized corrosion are quite complex and have been the subject of many experimental studies. LÄS MER
7. Chloride profiling in marine concrete - methods and tools for sampling
Sammanfattning : This project focuses on how to determine the chloride content in concrete structures exposed to marine environment in an accurate way. When analyzing dust from dry drilling in concrete, it is very often a fact that the chloride profiles show extensive variations even if the sampling has been performed within a very concentrated area with the sampling points close to each other.

8. Chloride transport and chloride thresholdvalues-Studies on concretes and mortars with Portland cement and limestone blended cement
Sammanfattning : Reinforced concrete is one of the most widely used building materials and if it is properly designed and produced, it is an extremely durable material with a service life up to 100 years. However, under certain environmental conditions the service life of reinforced concrete structures is more limited. LÄS MER
9. Chloride Channels and Brown Fat Cells
Sammanfattning : Chloride ion channels are macromolecular pores providing for passage of chloride ions (and certain other inorganic and organic anions) through the cell membrane, down their electrochemical gradients. Chloride channels are differentially expressed in various cells, to best suit specific cellular activities. LÄS MER
10. Chloride Induced Corrosion of Steel Bars in Fibre Reinforced Concrete
Sammanfattning : Chloride-induced corrosion of reinforcement is the most widespread degradation mechanism affecting the durability of reinforced concrete structures. Macro-cracks provide a preferential path for moisture, oxygen and Cl ions to reach the embedded reinforcement, playing a major role in their total transport. LÄS MER
