The present invention provides a cement admixture that comprises at least one of a carboxylic acid based copolymer comprising a reactive surfactant as a monomer or a copolymer salt obtained by neutralizing the copolymer with an alkaline substance, a method for preparing the same, and a cement composition comprising the same. The cement admixture of the present invention increases composition fluidity even at a high water-reducing formulation by improving dispersibility of cement particles, prevents a decrease of fluidity as the function of time, and offers good workability by supplying an adequate amount of air flow continuously.
