Title:
APPARATUS AND METHOD FOR DETECTING CHLORIDE ION CONTENT IN CONCRETE ON THE BASIS OF GRAPHENE/CEMENT COMPOSITE MATERIAL
Document Type and Number:
WIPO Patent Application WO/2018/103463
Kind Code:
A1
Abstract:
An apparatus for detecting chloride ion content in a concrete on the basis of a graphene/cement composite material, comprising a composite material (1) and a humidity sensor (6) which are positioned in a concrete protection layer, and also comprising an impedance tester (4) and a humidity detector (7) which are positioned at the outside of the concrete; the composite material (1) is a cuboid, and stainless steel nets (2) are respectively laminated to two horizontal end surfaces of the cuboid, the stainless steel nets (2) being respectively welded with wires; the composite material is connected to the impedance tester (4) at the outside of the concrete by means of the wires (3), and the composite material is coated with a sealing layer (8); the composite material (1) is composed of cement and graphene, silicon powder and an antifoaming agent which are doped in the cement, the doping amount of the graphene being 0.5-3% of the mass of the cement, the doping amount of the silicon powder being 5-20% of the mass of the cement, and the doping amount of the antifoaming agent being 0.05-0.3% of the mass of the cement. Said detection apparatus is not only compatible with a concrete environment, but may also monitor in real time the concentration growth of chloride ions in environments of different humidity.
