Permeability and long-term durability of concrete in final repository conditions; Betonin tiiviys ja saeilyvyys loppusijoitusolosuhteissa

Technical Report:

Abstract

The interrelation of the permeability properties and longterm durability especially in wet repository conditions has been studied. The study is based on the author`s long-term experience, literary survey and experiments on the durability, service life prediction, and on water and gas permeability. Degradation models and experimental results on water and gas permeability are presented. The experiments made indicated that high class concrete is practically water and gas tight, especially in the long run when stored under water. This meant that there will hardly be any mass transfer into concrete or out of it, if concrete is of good quality. Concrete structures can be designed to meet the required service life. It can be said that practically the precision increases and the scatter decreases in the service life estimation significantly when the thickness of the anticipated deteriorated surface layer is smaller due to the higher concrete quality. The service life of well-designed concrete silo walls made of high class concrete can be predicted to be at least 1000 years in the repository conditions. (orig.).
