摘　　要：为了对再碱化技术的现场应用进行深入的研究,选取浙江省湖州市頔塘碑亭碳化钢筋混凝土栏杆构件作为实验对象,依据欧洲相关技术规范对该栏杆进行外加电源式再碱化修复处理,并在修复后1个月、7个月和12个月对再碱化处理的效果进行跟踪测试与分析评估。结果表明,再碱化处理可以有效地提高混凝土保护层的碱性,降低钢筋的腐蚀概率,并且在1年的时间内有较好的耐久性,同时没有引起明显的副作用。该研究为再碱化技术在钢筋混凝土历史文物建筑修复领域的应用与推广提供了实验依据和工程经验。A realkalization rehabilitation treatment by impressed current is applied on one reinforced concrete railing of Ditang pavilion according to the Europe technology specifications in order to study the field test of realkalization technology. The treatment efficiency is followed and analyzed one month, seven months and twelve months after the treatment. The results show that the realkalization treatment can increase the alkalinity of concrete cover and decrease the corrosion probability of steel rebars. One-year durability of the treatment is also confirmed. Moreover, no side effect on concrete is detected after treatment. The study provides laboratory analysis basis and on site experience for the treatment application and promotion on historical monuments of reinforced concrete structure.
