Title:
STRENGTH SIGNAL MEASURING METHOD AND DEVICE FOR MONITORING STRENGTH OF HYDRATION REACTION MATERIAL STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2022/065595
Kind Code:
A1
Abstract:
The present invention provides a strength signal measuring method and device for monitoring strength of a hydration reaction material structure. A concrete structure or the like, which is a sort of structure formed of a hydration reaction material, exhibits a transmission speed inside the material and a response characteristic based on an excitation frequency, which are different according to strength, elastic modulus, and the like when vibration by an external factor is applied to. This may be used to measure strength of a structure and the ground to reliably monitor strength of a structure. The device can be made compact to secure portability and mobility, thereby measuring strength regardless of location.
