DEVELOPMENT OF THE TECHNOLOGY UTILIZING IC-TAGS FOR TRACEABILITY OF CONCRETE

−Evaluation of IC-tags put into fresh concrete at mixing process−

Abstract

In this paper, the basic experiments aiming at the technical establishment utilizing IC-tags which performs information management of concrete were shown, when the IC-tags were thrown into the fresh concrete at mixing process. The durability of IC-tags against the mixing, agitating, and compressive strength of concrete were examined by the tests which we extracted as the most fundamental experiment. It was clarified that the IC-tags, which do not assume supplying to concrete, beard the various external force at the mixing and agitating process of concrete. Moreover, the result that compressive strength did not decreased was obtained when an IC-tag was installed inside concrete specimen.
