A Study on the Corrosion Inhibiting Effect of Mortar with High Nitrite Content

This paper reports the effect of coating the concrete surfaces with mortar of high nitrite content on corrosion protection of reinforcing bars within concrete containing chlorides. Accelerated corrosion tests in a glass house and outdoor exposure tests were conducted over a period of 5 years. Specimens were made with using concrete containing 0.3-4.0 kg/m3 chlorides. Reinforcing bars were embedded with different cover depths in the specimens,...
