Abstract:
To evaluate the real durability of concrete, it is necessary, but difficult, to observe actual concrete structures over a long period. A durability test began in 1897 at the port of Otaru in Japan. It's purpose was to determine mix proportions and to evaluate durability. This 100-year-old project involves a series of tensile-strength tests with mortar specimens. As a continuous test, it is the longest in the world.
