复合阻锈剂对改性渗浇钢纤维混凝土导电性能的影响研究

为了解决改性后渗浇钢纤维混凝土(Slurry Infiltrated Fiber Concrete,简称SIFCON)由于金属导电相锈蚀而导致电阻率升高的问题,进行了掺入复合阻锈剂试验研究.结果表明:(1)掺入复合阻锈剂能进一步提高改性SIFCON的导电性能;(2)在自然状态下复合阻锈剂的掺人可是改性SIFCON在1.5 a的长龄期内,仍保持稳定的导电性能;(3)在144 h内饱水状态下,试件的电阻率无明显变化,证明复合阻锈剂可有效地保护金属相在不同条件下免受锈蚀影响.

Effect of the rust inhibitor on the conductive properties of SIFCON

The mixed compound rust inhibitor test was carried out in order to solve the problem of the rising resistivities due to the rust of the metal phase in modified slurry infiltrated fiber concrete.The experimental results show:(1) The compound rust inhibitor improves the electrical conductivity of modified slurry infiltrated fiber concrete.(2) Under the natural conditions,to mix compound rust inhibitor can make the specimen keep high table electrical conductivities in 1.5 years.(3) Under the saturated moisture conditions,the resistivities of the specimen do not change obviously in 144 hours,these prove that the compound rust inhibitor can effectively protect the metal phase from the rust under different conditions.
