SYSTEMS AND METHODS UTILIZING CARBON NANOFIBER AGGREGATE FOR PERFORMANCE MONITORING OF CONCRETE STRUCTURES

A carbon nanofiber aggregate (CNFA) system and method provides self-sensing capabilities that can be used to detect strain, moisture, and temperature changes. The CNFA may include cement, aggregate, silica fume, high-range water reducer (HRWR), and/or carbon nanofibers. The metal meshes in the CNFA...

Beschreibung
Zusammenfassung:	A carbon nanofiber aggregate (CNFA) system and method provides self-sensing capabilities that can be used to detect strain, moisture, and temperature changes. The CNFA may include cement, aggregate, silica fume, high-range water reducer (HRWR), and/or carbon nanofibers. The metal meshes in the CNFA may be utilized to monitor the electric properties of the CNFA to detect strain, moisture, and temperature changes. The CNFA may be embedded in concrete structures to allow detection of strain, moisture, and temperature changes that may cause damage to structures. Several metal meshes may be embedded in the CNFA.
