Abstract

This study investigated the chloride-ion permeability of C30 concrete by adding bamboo fibers with different treatments (untreated, treated with calcium hydroxide solution and treated with sodium hydroxide solution) and different dosages. Three testing methods, namely the electric-flux method, AC test method and the RCM method, were used to characterize the concrete. Parameters such as electric-flux value, AC resistivity and chloride-ion diffusion coefficient were obtained. Results showed that the surface impurities of the bamboo fibers treated with calcium hydroxide solution were removed and the thermal stability of the bamboo fibers was improved, which can effectively enhance the chloride-ion permeability of concrete. Compared to untreated bamboo fibers, the improvement rate was between 14 % and 17 %. Sodium hydroxide is a strong alkaline solution, which can easily disrupt the structure of bamboo fibers and reduce the resistance of concrete to chloride-ion penetration. The best chloride-ion permeability was achieved when the bamboo fiber content reached 2 %. The electric-flux method, AC test method, and the RCM method were mutually validated with good correlation. It is recommended to choose a suitable and simple method for testing. Bamboo-fiber concrete lays a solid foundation for the future transformation of the civil-engineering industry.

竹纤维加固混凝土氯离子渗透性实验研究

本研究通过添加不同处理（未处理、氢氧化钙溶液处理和氢氧化钠溶液处理）和不同剂量的竹纤维，研究了 C30 混凝土的氯离子渗透性。三种测试方法，即电通量法、交流测试法和 RCM 法，用于表征混凝土。得出了电通量、交流电阻率和氯离子扩散系数等参数。结果表明，用氢氧化钙溶液处理过的竹纤维表面杂质被去除，竹纤维的热稳定性得到改善，能有效提高混凝土的氯离子渗透性。与未经处理的竹纤维相比，改善率介于 14 % 到 17 % 之间。氢氧化钠是一种强碱性溶液，容易破坏竹纤维的结构，降低混凝土抗氯离子渗透的能力。当竹纤维含量达到 2 % 时，氯离子渗透性最好。电流量法、交流试验法和 RCM 法相互验证，相关性良好。建议选择合适且简单的方法进行测试。竹纤维混凝土为未来土木工程行业的转型奠定了坚实的基础。
