摘要
PURPOSE: To perform injection of a shadowing agent and injection of a repair material through one action by a method wherein a repair material mixed with a cesium carbonate water solution is injected in the cracks of concrete. ;CONSTITUTION: Adhesion performance of a repair material mixed with a shadowing agent is by no means inferior to a general repair material. Further, fluidity is high, the repair material enters fine gaps, and a shadowing agent is dissolved or stably dispersed in the repair material. A substance having high X-ray absorbing power is selected as the mixing shadowing agent. A substance wherein cesium carbonate produces a water solution being mixed in epoxy resin is used as a substance to meet the necessary conditions and a ratio of cesium carbonate water solution in epoxy resin is properly selected. A repair material mixed with the cesium carbonate as described above penetrates fine cracks 12 of concrete and provides excellent repair capacity and produces a sufficient shadowing effect for detection of the internal state of a crack.;COPYRIGHT: (C)1995,JPO
