PURPOSE:To provide the title composition good in fluidity to be used for construction materials requiring fluidity besides wall materials, maintenances, and floorings. CONSTITUTION:The objective polymer cement composition comprising (A) a polymer latex, (B) a defoaming agent, (C) a water reducing agent, and (D) a hydraulic material with the soluble alkali level of <=3,000mg/l on a Na2O weight basis. Use of the polymer cement composition will secure adequate workability without impairing its fluidity even at low water/cement ratios, giving cement-set forms excellent in flexural strength and bond strength and improved in denseness, durability and crack resistance. |
