摘　　要：海工混凝土在海洋工程建设组成中占据了主要地位,其性能极大程度上决定了海工构筑物的使用周期,进而阻锈剂对其性能影响成为研究热点。因此,文中通过掺入不同掺量的亚硝酸钠、Sika Ferrogard 901复合氨基醇阻锈剂、K-16钢筋阻锈剂3种阻锈剂,从海工混凝土的新拌性能、抗压强度及干缩性能方面入手,综合研究阻锈剂对海工混凝土性能的影响。结果显示亚硝酸钠、Sika Ferrogard 901复合氨基醇阻锈剂掺量越大,对混凝土性能的影响越小,最佳掺量分别是6%、4%。而K-16钢筋阻锈剂相反,掺量越大对混凝土性能影响越大,最佳掺量为4 kg/m3。研究为阻锈剂在海工建筑工程中的应用提供一定参考意义。Marine concrete plays a crucial role in the construction of marine engineering structures,and its performance largely determines the service life of these structures.As a result,the impact of rust inhibitors on its performance has become a research focus.In this study,three rust inhibitors-sodium nitrite,Sika Ferrogard 901 composite amino alcohol,and K-16 rebar rust inhibitor-are incorporated into marine concrete at different dosages.The influence of these inhibitors on the fresh properties,compressive strength,and drying shrinkage of the concrete is comprehensively studied.The results show that as the dosage of sodium nitrite and Sika Ferrogard 901 composite amino alcohol increases,their impact on concrete performance becomes smaller,with the optimal dosages being 6%and 4%,respectively.On the other hand,the K-16 rebar rust inhibitor exhibits the opposite effect,with a greater dosage leading to a more significant impact on concrete performance,and the optimal dosage is 4 kg/m3.This study provides valuable reference for the application of rust inhibitors in marine construction engineering.
