PROBLEM TO BE SOLVED: To provide a polymer cement composition which is easily manufactured on site, has such flowability that the workability is not disturbed in construction and gives high strength and high toughness. SOLUTION: Disclosed is the polymer cement composition containing cement, water, aggregate, a polymer and a high strength short fiber having≥20 cN/dtex tensile strength, wherein 1-20 pts.mass of the polymer is blended based on 100 pts.mass of the cement, and the high strength short fiber contained in the polymer cement composition has a fiber length of 1-18 mm, single yarn fineness of 0.3-10 dtex and a mixing rate of 0.1-5 vol.%.
