Outline of Final Research Achievements

The purpose of this study was to construct a basic model on estimation of aged deterioration of concrete based on several investigation results which were obtained from some exposure tests conducted in whole of Japan during 10 years. This study investigated the influence of the environment on some properties of concrete. As a result, it was confirmed that the concrete with high water to cement ratio was susceptible to environmental effects through compressive test, water permeability test and carbonation test.
