To obtain a fiber-reinforced cement molded body having excellent wet thermal resistance, and the like, and well improved in mechanical strength, and the like, and to provide a method for producing the molded body, and further to provide a cement slurry capable of providing a cement molded body excellent in various performances.

The fiber-reinforced cement molded body is obtained from a cement slurry comprising at least 35 to 60 mass% of cement, 35 to 60 mass% of silicious powder, 0.1 to 5 mass% of polypropylene-based fiber having 0.1 to 10 dtex single fiber denier, and 0.1 to 5 mass% of a vinylalcohol-based polymer having 60% or more extraction rate with an alkaline liquid.
