摘要
本文旨在研究电渗技术对模网钢管滤水混凝土耐久性的影响.通过电镜对模网钢管滤水混凝土试件的微观形貌进行比较;通过氯离子扩散实验对模网钢管滤水混凝土的抗渗性进行分析.实验表明采用电渗技术能显著提高模网钢管滤水混凝土的滤水速度、降低混凝土的凝结水灰比,试件的界面和孔级配得以改善.电渗后的模网钢管滤水混凝土的密实度和抗氯离子渗透性能有较大的提高.
The purpose of this paper is to investigate the effect of electroosmosis technology on durability of filtering concrete.The microstructures were compared by SEM.The ability to resist chloride ion penetration wase studied by chloride ion penetration test.The experimental results indicate that electroosmosis technology can further the filtering velocity markedly,reduce the water cement ratio of solidification and improve interfacial microstructures significantly.The compactness and ability to resist chloride ion penetration of filtering concrete would be greatly improved after electroosmosis.
