Funded by SP Sveriges Tekniska Forskningsinstitut AB Research Institute, Sweden Since the spring of a large number of concrete slabs of about 40 different concrete compositions were exposed at a field test site in Träslövsläges port of Varberg on the Swedish west coast.
Through a number of research projects thorough mapping of moisture and chloride profiles in concrete specimens have been made after 1, 2, 5 and 10 years of exposure. The overall objective of the project is to investigate chloride ingress and reinforcement corrosion in concrete specimens after 20 years of exposure.
It is the first time in history that we have access to as well-documented long-term tests under natural exposure. Measurement after 20 years of exposure provides unique data that contributes to more reliable service life designs. This knowledge can be used both in material selection and design of new concrete structures but also in the assessment of remaining life and as a basis for planning of maintenance and repairs to existing structures.
The results will also lead to increased knowledge about how quickly chlorides penetrate into the concrete with different dating sites i vittinge and increased knowledge of chloride threshold dating site träslövsläge for these binders.
This knowledge is important for making the right choice of materials from a sustainability perspective.
The project is carried out at the Division of Building Technology in the research group Building Materials. Keywords: Cement, chloride, concrete, corrosion, durability, moisture This page is only available in english Page manager Published: Fri 07 Sep We have received your message.
