AMCI迁移型防腐阻锈剂的性能研究

Property research of a kind of migrating corrosion inhibitor-AMCI

钢筋腐蚀成为当今世界影响混凝土耐久性的主要因素。特别在氯盐环境中,钢筋腐蚀是影响混凝土耐久性首要因素。简要介绍了自主研发的AMCI迁移型防腐阻锈剂的抗氯离子侵蚀性能,通过新拌砂浆法、溶液浸泡法以及干湿冷热循环等试验,显示AMCI具有良好的抗氯离子侵蚀作用和一定迁移作用。

The corrosion of steel bars in concrete has become the major cause that influences the durability of concrete.The properties of AMCI corrosion inhibitor,developed by BBCIR（Beijing Building Construction Research Institute） independently,was studied.By a series test based on YB/T 9231—98,it was evidenced that AMCI can reduce the corrosion rate of steel reinforcements embedded in a hardened concrete structure.It was also investigated that AMCI has migrating ability.
