Abstract

In order to clarify the deterioration mechanisms of concrete caused by alkali-silica reaction (ASR) and sea water attack in marine environment, both the in-situ survey and the laboratory test using cores were carried out. As a experimental result, the influence of the petrographic feature of reactive andesite aggregates used, the mix proportion of concrete and the structural type, and the environmental condition around the structure on the degree of damages in ASR affected structures was investigated especially in relation to the amount of ASR gel and other reaction products. Furthermore, a new test method to evaluate the residual expansion capacity of cores in marine environment was proposed.
