LD-2复合缓蚀剂对海水介质混凝土中钢筋阻锈作用研究
, PP. 494-500
Keywords: 钢筋混凝土,腐蚀,海水,缓蚀剂
Abstract:
利用电化学检测技术和海水浸泡试验等方法,观测和研究了经筛选研制的LD_2复合缓蚀剂对海水介质中钢筋腐蚀电化学行为的影响,考察和评价了复合缓蚀剂对钢筋的阻锈作用.结果表明,LD_2复合缓蚀剂主要起阳极型缓蚀剂作用.在海水中加入25g·L-1复合缓蚀剂后,钢筋的腐蚀电位提高约0.220V,腐蚀电流降低至未加缓蚀剂的1%,缓蚀效率达99%.钢筋混凝土试样在海水中浸泡2年,表明混凝土中加入占水泥重量1.0%～2.5%LD_2复合缓蚀剂时,能有效阻止混凝土中钢筋的腐蚀
