PRESS DIE MADE OF CONCRETE AND ITS PRODUCTION

摘要

PROBLEM TO BE SOLVED: To provide a press die made of a concrete having good adhesion of a surface layer and a high dimensional precision and its production method. SOLUTION: A concrete part is solidified by vapor curing. Successively, by forming a surface material layer 70 on a press forming surface of the concrete part with using an aggregate 65 of a constituting element of the concrete part for an anchor, the press die made of a concrete part having the surface layer on the concrete part is produced.
