Some cracks existed in reinforced concrete building in Yuzhou to Changge section of Middle Route Project of South to North Water Diversion. The cause of this cracks was analyzed and 3 construction methods of crack treatment were introduced, including surface coating, fissure filling and grouting, so was the construction process. In order to prevent cracking and ensure the construction quality, the key points of quality control were put forward according to the quality defects of the concrete struc-ture and crack treatment regulations of reinforcement concrete structure.
