摘　　要：亚硝酸盐作为应用时间最长、效果最显著的一类混凝土钢筋阻锈剂,其在应用过程中,由于掺量不足引起的加速腐蚀问题、以及环保问题一直备受争论。在具体试验研究及相关文献资料的基础上,对亚硝酸盐钢筋阻锈剂的应用问题进行了深入探讨,指出亚硝酸盐钢筋阻锈剂并不存在加速腐蚀的问题,而它的环保问题也并非人们通常所认为的严重。There are always many controversies on the application of nitrite, such as steel bar＇s accelerated corrosion due to insufficient dosage of nitrite, and a series of environmental problems caused by nitrite, though nitrite has the longest usage history and best anticorrosion effect among all kinds of corrosion inhibitors used in concrete.This paper gives a thorough research on the above problems based on experiments and literature, and following opinions are proposed：nitrite does not cause accelerated corrosion to the reinforcing steel bars, and the environmental problems caused by nitrite are also not as serious as what people always think.

关 键 词：亚硝酸盐 阻锈剂 加速腐蚀 环保
