MANUFACTURE OF CONCRETE PRODUCT

摘要

PROBLEM TO BE SOLVED: To easily manufacture a large-scaled imitation rock by a method wherein the rock texture representation of a concrete product is executed easily with a good workability. SOLUTION: A matrix 2 is formed by unevenly deforming a plastically deformable foil-like material. A liquid plastic material 4, which hardens in the ordinary temperature and turns into an elastically deformable matter is brought into contact with the surface of the matrix 2 so as to produce a form by hardening the contacted plastic material 4 in the ordinary temperature. Then, by placing a concrete in the form, a molding is released from the form at the stage that a demoldable molding is produced through the hardening of the concrete.
