A zeolite supported organic corrosion inhibitor with high loading efficiency was obtained by loading a synthesized lauric acid imidazoline (LAI) in the Ca²⁺-exchanged zeolite (Ca²⁺-zeolite) framework. The influences of the as-prepared Ca²⁺-zeolite supported LAI (Ca²⁺-ZSLAI) as an admixture in porosity and compressive strength of the resulting cement mortar were examined. The protective effect of Ca²⁺-ZSLAI against steel corrosion of steel-mortar immersed in NaCl solution was discussed upon. The properties of the steel reinforced mortar incorporating Ca²⁺-ZSLAI was compared with the reference mortar specimen without corrosion inhibitor and the specimen solely with LAI or Ca²⁺-zeolite. The steel corrosion resistance performance of Ca²⁺-ZSLAI was revealed by electrochemical testing on steel reinforced mortar during the chloride ions accelerated corrosion test. Experimental results revealed that mortar with 6% of cement replaced by Ca²⁺-zeolite saturatedly supported LAI as corrosion inhibition additive presented 14% higher compressive strength and 23% lower total porosity compared to the reference mortar. Besides, such dose of inhibitor could retain 92% corrosion inhibition efficiency of the embedded steel after 142 immersion days. The excellent corrosion resistance efficacy of Ca²⁺-ZSLAI was ascribed to the chloride “binding capacity” of the densified mortar substrate improved by the filling and pozzolanic effect of Ca²⁺-zeolite and the chloride “barrier capacity” of the protective interfacial film deposited by the LAI released from the Ca²⁺-zeolite carrier.

通过将合成的月桂酸咪唑啉（LAI）负载在Ca ²⁺交换的沸石（Ca 2 ^+-沸石）骨架中，获得了具有高负载效率的沸石负载的有机腐蚀抑制剂。考察了制备的Ca 2 ^+-沸石负载的LAI（Ca ²⁺ -ZSLAI）作为混合物对所得水泥砂浆孔隙率和抗压强度的影响。讨论了Ca ²⁺ -ZSLAI对浸在NaCl溶液中的钢砂浆钢腐蚀的防护作用。将掺有Ca ²⁺ -ZSLAI的钢砂浆的性能与不含腐蚀抑制剂的参比砂浆样品以及仅含LAI或Ca的样品进行了比较²⁺沸石。Ca ²⁺ -ZSLAI的耐钢腐蚀性能通过氯离子加速腐蚀试验中钢筋增强砂浆的电化学测试得到。实验结果表明，与参考砂浆相比，用6％水泥代替Ca ²⁺沸石的饱和支撑LAI替代的砂浆作为缓蚀剂的抗压强度提高了14％，总孔隙率降低了23％。此外，这种剂量的抑制剂在浸入142天后仍能保持嵌入钢的92％腐蚀抑制效率。Ca ²⁺具有出色的抗腐蚀功效-ZSLAI归因于Ca 2 ^+-沸石的填充和火山灰作用以及由Ca ²释放的LAI沉积的保护性界面膜的氯化物“屏障能力”，提高了致密砂浆基材的氯化物“结合能力”。^+-沸石载体。
