NOVELTY - A composite cement-based material comprises cement mortar mixed with carbon fiber materials grafted with carbon nanotubes. USE - Composite cement-based material used for sensor (claimed). ADVANTAGE - The composite cement-based material provides sensor having simple structure, high accuracy, and suppressed generation of damage and corrosion. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a composite cement-based material sensor, which involves arranging a conductive anti-corrosion unit on the surface of the composite cement-based material, arranging an epoxy resin coating layer on the conductive antirust portion, and arranging a heat preservation board on the outer side of the epoxy resin coating layer.
