To make the existing structures more sustainable and to utilize these structures for longer period of time, maintenance is one of the most important works. Usually, concrete structures can be used for more than hundred years, but due to deterioration, accidents, etc., some of the structures must be repaired within 50 years. This paper clarifies the present situation in Japan related to maintenance of existing concrete structures. Some examples are shown how to prevent the deterioration and how to deal with the problems after they are deteriorated. 000002054 540__ $$aText je chráněný podle autorského zákona č. 121/2000 Sb. 000002054 653__ $$amaintenance, sustainable, concrete structures, natural hazards, deterioration, life cycle CO2 000002054 7112_ $$aFirst International Conference on Concrete Sustainability$$cTokyo (JP)$$d2013-05-27 / 2013-05-29$$gICCS13 000002054 720__ $$aUOMOTO, Taketo 000002054 8560_ $$ffischerc@itam.cas.cz 000002054 8564_ $$s1828161$$uhttp://invenio.itam.cas.cz/record/2054/files/Keynote_Speech_1.pdf$$y Original version of the author's contribution as presented on CD, . 000002054 962__ $$r2053 000002054 980__ $$aPAPER
