就我所知钢筋阻锈剂主要分为渗透型和添加型两种。
渗透型适用于已建的建筑物，直接涂刷在混凝土表面即可；
添加型适用于新建的建筑物，与混凝土一同搅拌即可。

我单位生产的抗硫阻锈外加剂物理阻锈与化学阻锈结合，效果很不错。

国外老工程修复中使用钢筋阻锈剂的问题仍然存在争议（请看文摘或全文）：

——发展渗透型阻锈剂(MCI)以保护混凝土中钢筋以防腐蚀。用于已有混凝土结构的修复，可以加到混凝土修补砂浆中或者涂敷混凝土表面（渗透）
Migrating corrosion inhibitors (MCI) were developed to protect steel rebar from corrosion in concrete. They were designed to be incorporated as an admixture during concrete batching or used for surface impregnation of existing concrete structures.

——讨论了混凝土修复工业利用钢筋阻锈剂的问题。这类化学物质可以混合到修补混凝土中或者涂在硬混凝土表面渗透到钢筋，很显然，渗透过程更困难。掺入和表面涂敷两种情况，均缺乏资料和现场使用的数据。特别是阻锈剂通过硬混凝土的渗透，是需要评估的。在此方面，欧洲和美国的建筑业、运输业和中立派研究者正率先进行研究。
Discusses the use of corrosion inhibitors for steel by the concrete repair industry. The chemical agents can either be mixed into fresh concrete or are applied to the surface (or in holes) of hardened concrete, permeating through to the internal steel reinforcement. Obviously the latter is a more difficult procedure, but in both cases there is a lack of information and field data about inhibitor performance. In particular, the claims made for the transport of inhibitors through hardened concrete need to be assessed. Research in this area is currently taking place, however, in both Europe and the US by building and transport establishments and independent researchers.

——加拿大IRC在已有的10跨混凝土桥上进行了试验研究，使用了8种阻锈剂（有机和无机类）。试验室研究表明，一种有机类和一种无机类对降低腐蚀很有效；但现场试验表明，仅一种无机阻锈剂比较好。
IRC researchers selected 10 consecutive spans of the bridge for testing. Eight organic and inorganic corrosion-inhibiting systems were applied to the spans。A series of comparative laboratory experiments showed that one of the organic-based admixtures and one of the inorganic-based admixtures were very effective in reducing corrosion. In the field, however, the
inorganic-based inhibitor system performed better than the other inhibitor systems.

——钢筋混凝土桥梁修复利用钢筋阻锈剂的长期有效性（美国联邦公路局报告）
为了确定钢筋阻锈剂的长期有效能，美国联邦公路局(FHWA)于1994—1999年的5年时间，进行了现场试验研究。所有4个使用场地的腐蚀速率的测试结果表明，含与不含阻锈剂的修补砂浆，其效果没有显示出差别来。

Long-Term Performance of Corrosion Inhibitors Used in Repair of Reinforced Concrete

the Federal Highway Administration (FHWA) in August 1994 and ended in July 1999. The primary goal of this study was to monitor the SHRP field sites for 5 years to determine the long-term effectiveness of corrosion inhibitors。
At all four sites, the results of the visual and delamination surveys and corrosion rate measurements did not show any difference between patches containing corrosion inhibitors and those that did not contain them.
