Abstract
Construction material, such as cement, has high transportation cost, and it has developed as local industry. By the TBT agreement in 1995, the international standard (ISO) was transposed to the standard of Japan (JIS) in a series of test method also in cement. There is no international standard in quality standard of cement. Recently EU standard was approved. EU pushes EU standard of specification of cement to the draft of ISO under Vienna agreement according to the original strategy of EU and major cement company in EU. The standard of Japan (JIS) was the level of the minimum standard, which the government purchases as a thing, but it was not approved under the strategy of cement industry without rather bigger confusion. Until now, as an industrial basic material, quality was not dealt with corporate strategy in Japan cement industry. According to EU standard of cement specification, EU cement industry also has a responsibility to explain to the user. Japan cement industry does not take account of these matters, which are not a problem solvable by the conventional government leading. The impact of normalization of international standard (ISO) on the cement industry of Japan and its correspondence taken as future our country are considered in this paper. The rationality in EN standard was desirable to make it useful for the user, manufacturers, and people, to take the completeness as a standard.
