Abstract:The Sanjiadian Barrage in Beijing has been operating for more than 48 years.Partial structures are seriously deteriorated because of aging and need to mend and consolidate.This paper introduced the advanced renovating measures against concrete carbonize,crack and surface erosion.Those measures include flexibility covering,chemical grout,stick carbon fiber and Sproy of Polyurea Elastomer(SPUA),which are valuable experience for similar rehabilitation project.
Keywords:Concrete Chemical grout SPUA Rehabilitation
