| 摘要： | The ability of chloride ions to penetrate concrete must be known for design as well as quality control purposes. This document reviews the current common methods for determining chloride penetrability of concrete. First, some theoretical background of what influences the penetration of chlorides into concrete is presented. The different mechanisms of chloride penetration are presented, followed by a further elaboration of the chloride diffusion theory. The influence of basic properties of concrete on its chloride penetrability is also discussed. Next, individual test procedures are presented. Discussed first are the existing long-term procedures, namely the salt ponding test (AASHTO T259) and the Nordtest bulk diffusion test (NTBuild 443). The existing short-term tests are then presented. For each test, the procedure, the theoretical basis, and any advantages and disadvantages are presented. Also included in this document as an appendix is a glossary of some of the common terms related to chloride ingress testing and measurement. |
