关于PVA混凝土的抗氯离子侵蚀性能研究

Corrosion Resistance of PVA Concrete Based on Chlorine Ion

以不同的水灰比(质量比)和纤维体积掺量制作实验试样,通过基本力学与氯离子浓度检测试验筛选出最佳的水灰比和掺量范围并给出变化规律。结果表明在一定范围内,抗压抗折能力与水灰比呈负相关趋势。以四个侵蚀龄期的实验数据来看,0.15%体积掺量的PVA混凝土氯离子扩散效果最差。

The experimental samples were made with different water-cement ratio and fiber content.The optimum water-cement ratio and content range were selected by basic mechanics and chloride concentration test,and the variation law was given.The results show that there is a negative correlation between compressive and flexural capacity and water-cement ratio.According to the experimental data of four erosion ages,the chlorine ion diffusion effect of 0.15%volume content PVA concrete is the worst.
