Experimental Study of Sulphate Attack on Steel Embedded in Reinforced Concrete
Resumen
AbstractCorrosion is one of the biggest problems of steel in reinforced concrete (RC) structure, which deteriorates the durability of concrete structure at a considerable rate. In this paper, we have studied the corrosion density, corrosion rate, and resistivity to a solution of 0.78 N H2SO4 with the help of electrochemical process to a temperature range of 307–309±1 K by using Stern Geary equation and Tafel slope on 12 and 8 mmÏ• bar. The current work gives a deep review on the corrosion rate and weight loss caused due to sulphuric acid attack on steel embedded in concrete in existing and new infrastructure as well as building infrastructure. The result obtained shows that corrosion rate of mild steel bar of 8 mmÏ• in H2SO4 is fast as compared to 12 mmÏ• bar taken periodically. Keywords: Corrosion, Fe 415 mild steel, electrochemical, resistivity, corrosion rate, sulphuric acid Cite this Article Trivedi Ashutosh S, Sharma RP.
