The effects of the cellulose ether MFS6003 on the properties of polymer cementitious waterproof slurry were studied.The results showed that the workability,sag-resistance and hydrophobicity of polymer cementitious waterproof slurry are increased clearly with the increase of MFS6003 dosage.Cellulose ether has verylitlle effect on the compressive strength,flexual strength,trans-verse deformation and impermeability of polymer cementitious waterproof slurry.When the amount of MFS6003 is 0.07％,the imper-meability of waterproof slurry is more than 0.5 MPa,the transverse deformation capacity is 2.5 mm,and the 28 d shrinkage rate is 0.28％.Meet the requirements of Type Ⅰ products in JC/T 2090-2011"Polymer Modified Cement Slurry for Waterproof".
