【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。更多还原

【Abstract】 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.更多还原
