<p>PROBLEM TO BE SOLVED: To provide a method for producing a cement molded part capable of obtaining a cement molded part having stable strength even if the temperature of a green sheet is changed.SOLUTION: Provided is a method for producing a cement molded part including: a first step in which water is added to a mixed material essentially consisting of ordinary cement and early-strength cement, and kneading is performed; a second step in which the mixed material after the kneading is shaped to mold a green sheet; and a third step in which the green sheet is subjected to cure hardening. When the temperature of the green sheet is made low, in the mixed material of the first step, the blending ratio of the early-strength cement to the ordinary cement is made high. When the temperature of the green sheet is made high, the blending ratio of the early-strength cement to the ordinary cement is made low.</p> |
