摘要
目前将海砂应用于混凝土建设主要有两种途径,一是将海砂淡化处理为建筑用砂,二是在混凝土中添加抗氯剂来阻隔氯离子的渗透。通过研究各种抗氯剂对于海砂海水混凝土抗氯离子渗透性能的影响,结果表明:在各种抗氯剂中,偏高岭土和甲基硅酸钠效果最为明显,与不加抗氯剂的样品对比,其电通量分别降低了33.6%和41.6%,且对混凝土短期强度和长期强度均无影响。
At present,there are two main ways to apply sea sand to concrete construction,one is to desalinate sea sand for construction sand,the other is to add anti-chlorine agents in concrete to block the penetration of chlorine ions.In this paper,we studied the influence of various chlorine resistant agents on the chloride ion penetration resistance of sea sand seawater concrete.The results show that:among all kinds of chlorine resistant agents,the high territory and methane-siliconic acid sodium salt have the most obvious effects.Compared with the samples without chlorine resistant agents,their electric fluxes are reduced by 33.6%and 41.6%respectively,and they have no effect on the short-term and long-term strength of concrete.
