2. 1. Chloride profiling in marine concrete - methods and tools for sampling

   Author : Henrik Wall; Avdelningen för Byggnadsmaterial; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; klorider; betong; provtagning; concrete; sampling; chloride;

   Abstract : 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.

4. 2. Chloride initiated reinforcement corrosion in marine concrete

   Author : Paul Sandberg; Avdelningen för Byggnadsmaterial; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; w c ratio; cover thickness; chloride penetration; service life prediction; corrosion cells; chloride thresholds; field exposure tests; marine concrete; pozzolans; reinforcement corrosion; chloride binding; Building construction; Byggnadsteknik;

   Abstract : Factors affecting the total chloride threshold for initiation of pitting corrosion in reinforced concrete were investigated by means of field and laboratory exposure tests. Factors affecting the chloride penetration into concrete were also investigated by means of field tests. The thesis consists of a summary (86 p.) and 11 papers attached. READ MORE

5. 3. Chloride Transport in Concrete - Measurement and Prediction

   Author : Luping Tang; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : This doctoral work has been carried out to try to classify the basic theories involved in chloride transport in concrete, and at the same time to develop a measurement method and a prediction model for concrete structures submerged in sea water. Chloride binding accompanies almost all the transport processes and has a significant influence on chloride transport. READ MORE

6. 4. Service Life Assessment of Harbor Structures - Case studies of chloride ingress into concrete and sheet piling corrosion rates

   Author : Henrik Wall; Avdelningen för Byggnadsmaterial; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; chloride ingress; sampling methods; corrosion rates; sheet piling; ultra-sonic measurements; service life; durability; quay structures; harbor structures;

   Abstract : The two most used building materials in harbor structures are undoubtedly steel and concrete. These two materials are often combined in the structures of wharfs and quays where the steel sheet pile walls often have cap beams of reinforced concrete. READ MORE

7. 5. Man-made structures as habitat for marine faunal assemblages

   Author : Mathias H. Andersson; Sören Nylin; Hans Kautsky; Stockholms universitet; []
   Keywords : ;

   Abstract : Artificial reefs are structures placed in the sea to promote marine life. Although constructions such as oil-rigs, wind farms, bridges and pier pilings are built for other purposes, they could be regarded as artificial reefs as they add new surfaces in the oceans, susceptible to colonization by marine organism.
