Biopolymers are environmentally friendly polymers which are used as admixture for modifying their hydration. Several polymers, used as admixtures, are available for the construction material industry. In the present review, cellulose ethers, hydroxypropylmethyl cellulose (HPMC), hydroxyethylmethyl cellulose (HEMC), hydroxyethyl cellulose (HEC), chitosan, diutan, welan and xanthan gum, lignosulfonates, starch and microcellulose were included. The effects of each biopolymer in the cement mixture were explained. Key words:
