Chemical admixtures have been widely used for the purpose of a functional investment to cement concrete materials, and a large quantity of polymeric surfactants have been used as the component in chemical admixtures.In recent years, a chemical admixture, namely high-range AE water-reducing agent (HRWR) comprising from water-soluble graft copolymer have played an important role to the promotion of ultra high strength concrete for super high-rise RC structure.Therefore, this report relates especially to the role of HRWR for ultra high strength concrete. First of all in this articles, the fundamental principles and common properties to get the high strength of cementitious materials were explained, and continually the chemical structures of HRWR, cement dispersing mechanism and the application of ultra high strength concrete were reviewed.
