  • A multi-environmental time similarity theory of life prediction on coastal concrete structural durability

    A multi-environmental time similarity (METS) theory for durability assessment and life prediction is presented in this paper. The METS theory is able to connect the field inspections and the indoor accelerated tests by introducing a third reference site, which has certain service life and similar aggressive environment to the study objective. Thus, the correlation between the field inspection ...
