A New Kind of Rebar Inhibitor

In many domestic projects, most of rebar inhibitors contains the nitrite ingredient, which harms the environment. Due to the low poison and good inhibition function, a new kind of molybdate inhibitor was prepared. Its anti-rust performance was analyzed systematically by salt water immersion test, dry-wet-cold-hot circulation test, weight loss experiment and hardened mortar test, and was compared with a commercial inhibitor. The performance was verified further in concrete simulation liquid. The results show that it is an efficient, environmentally friendly rust inhibitor, and the best rust resistant effect was exhibited in a dosage of 3%.
