Quality control system of concrete and cement products using wireless IC tag

摘要

A quality control system of concrete and cement products is provided in which the manufacturing information on cement products of mortar or concrete can be checked at any time, the reliability is so high that there is no possibility of the recorded information being lost or falsified, there is no possibility of damage in concrete, and the directivity of the sensitivity of an antenna can be broadened. A quality control system of concrete and cement products writes into a wireless IC tag 1 equipped with an antenna section mixed in the manufacturing process of cement products kneading with cement, aggregate and water and measures the characteristic value, and an IC tag writer 7 coupled to the automatic measuring device automatically writes the characteristic value of the products measured by the automatic measuring device and the manufacturing information consisting of the dates of manufacture. The information recorded in the wireless IC tag in a structure can be read by an IC tag reader 11 after said cement products is cast in the construction field and becomes a structure.
