Abstract: Detection and reinforcement of a large stores framework deteriorated by chlorides induced corrosion, discusses the corrosion mechanism of chlorine, putting forward three kinds of reinforcing schemes, and the reinforcing schemes are compared. Using chemical grouting and enlarging section of the synthesis of framework reinforced. The practical running shows a good effect, results showed that the engineering reinforcement in 14 years, still can use safety. This method can be applied to the similar projects.
Keywords: chlorides;  corrosion;  RC structure;  detection;  reinforcement
