渗透结晶材料和粉煤灰对海工混凝土氯离子渗透性能的影响研究

Impact of Penetration Crystalline Material and Fly Ash on the Chloride Permeability of Marine Concrete

粉煤灰和渗透结晶材料对海工混凝土抗氯离子渗透性能有很大影响。采用了GB/T50082—2009中的快速氯离子迁移系数法和电通量法对海水环境下掺有粉煤灰和水泥基渗透结晶材料的混凝土进行测试。结果表明:在一定掺量范围内,随着粉煤灰和水泥基结晶材料掺量的增加,海水环境下混凝土抗氯离子渗透性能有显著提高。

Penetration crystalline material and fly ash have a great impact on the resistance to chloride ion permeability of marine concrete.In this paper,the rapid chloride ion migration method and the flux method based on GB/T50082—2009 were used to test the marine concrete mixed with fly ash and crystalline materials under sea water environment.The results showed that： in a certain dosage range,with crystalline materials and fly ash dosage increases,the resistance of concrete to chloride ion penetration was significantly increased under the see water environment.
