Composite cement-based material and composite cement-based material sensor
The invention discloses a composite cement-based material and a composite cement-based material sensor. The composite cement-based material comprises cement mortar, and the cement mortar is doped witha carbon fiber material grafted with carbon nanotubes. The composite cement-based material sensor comprises the composite cement-based material, a conductive rust-proof part arranged on the surface of the composite cement-based material, an epoxy resin coating layer arranged on the conductive rust-proof part, and an insulation board arranged on the outer side of the epoxy resin coating layer. Thecarbon fiber grafted with the carbon nanotubes is good in dispersity in a cement base and higher in interface bonding capacity with the cement base. The composite cement-based material sensor is simple in structure and sensitive in monitoring, can be suitable for mass concrete in various environments, and can accurately monitor the internal stress condition of the concrete so as to judge the damage degree and the corrosion condition of the concrete.
本发明公开了一种复合水泥基材料及复合水泥基材料传感器，该复合水泥基材料包括水泥砂浆，所述水泥砂浆中掺入有接枝碳纳米管的碳纤维材料。该复合水泥基材料传感器，包括上述的复合水泥基材料，设置在所述复合水泥基材料表面的导电防锈件，在所述导电防锈件上设置环氧树脂涂覆层，所述环氧树脂涂覆层外侧设有保温板。本发明接枝碳纳米管的碳纤维在水泥基中的分散性较好，且与水泥基体的界面结合能力更强。复合水泥基材料传感器结构简单、监测灵敏，能适用于各种环境的大体积混凝土，能准确监测混凝土内部受力情况，以判断其损伤程度和腐蚀状况。
