PROBLEM TO BE SOLVED: To provide a heavy weight polymer cement mortar capable of repairing a step with the thickness of several millimeters of a concrete structure using heavy weight concrete by being smeared thinly, and to provide a heavy weight polymer cement mortar hardly generating a crack, dry-out, exfoliation or float even when being smeared on the heavy weight concrete surface with the thickness of <1 millimeter.SOLUTION: The heavy weight polymer cement mortar contains, with respect to (A) 100 pts.mass of cement, (B) 180-400 pts.mass of an aggregate wherein the content rate of particles whose particle size is over 0.6 millimeter is ≤5 mass%, while the content rate of particles whose particle size is 0.15-0.3 mm is 40-60 mass%, and the specific gravity is 3.0-4.5, (C) 3-25 pts.mass of an organic binder, (D) 0.3-7 pts.mass of a deforming agent, and (E) 0.05-0.5 pt.mass of an organic thickener. |
