▎ 摘　　要

NOVELTY - The device has a humidity sensor coated with composite material. A composite impedance tester and a humidity detector are fixed in an outside of a concrete. A stainless steel net is welded with a lead. The composite impedance tester is connected with the outside of the concrete. A sealing layer i.e. epoxy resin sealing layer is coated with the composite material that is composed with graphite and silicon powder. Doping quantities of the graphite and the silicon powder are respectively about 0.5 - 3% and 5 - 20%. Doping quantity of antifoaming agent is about 0.05 - 0.3%. USE - Device for detecting chlorine ion graphene/cement composite material content in concrete. ADVANTAGE - The device carries chlorine ion concentration in real development according to different humidity environment monitoring process. DETAILED DESCRIPTION - The graphite is a single-layer graphene. An INDEPENDENT CLAIM is also included for a method for detecting chlorine ion graphene/cement composite material content in concrete. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic block diagram of a device for detecting chlorine ion graphene/cement composite material content in concrete.
