Self-sensing concrete capable of preventing corrosion of reinforcing steel bars and preparation method of self-sensing concrete
The invention discloses self-sensing concrete capable of preventing steel bar corrosion, which is prepared from the following components in percentage by weight: 14.9 to 65.0 percent of cementing material, 0.1 to 2.8 percent of conductive material, 0 to 71.7 percent of fine aggregate, 0 to 72.0 percent of coarse aggregate, 0 to 0.53 percent of water reducing agent and 21.1 to 40 percent of water, the conductive material is at least one of carbon black, carbon fibers and carbon nanotubes. According to the invention, the conductive material is added into the concrete, so that the steel bars in the concrete can be prevented from being rusted by adding the metal sheet at one position in the concrete mold, the service life of the steel bars in the whole building is prolonged, and the production cost is reduced.
本发明公开了一种防钢筋锈蚀自感知混凝土，按照重量百分数记，包括以下各组份：胶凝材料14.9％‑65.0％、导电材料0.1％‑2.8％、细骨料0‑71.7％、粗骨料0‑72.0％、减水剂0‑0.53％和水21.1‑40％；所述导电材料为炭黑、碳纤维和碳纳米管中的至少一种。本发明通过在混凝土中加入导电材料，使在混凝土模具中一处添加金属片即可实现混凝土中钢筋的防锈蚀，延长了整体建筑中钢筋的使用寿命，降低了生产成本。
