FORMWORK FOR CONCRETE MOLDING AND MANUFACTURING METHOD THEREOF AND MANUFACTURING METHOD OF CONCRETE WITH STEPPED SURFACE

摘要

PROBLEM TO BE SOLVED: To provide a formwork for concrete molding and a manufacturing method thereof, which can reduce dents such as air pockmark appearing on a step of a concrete surface when concrete with a stepped surface is manufactured, and a manufacturing method of the concrete with a stepped surface.SOLUTION: A formwork 10 for concrete molding comprises: a form surface 20 with a stepped part 24 that can provide a step 26 on a concrete surface; and a porous layer 22, which is disposed at least on the stepped part 24 of the form surface 20 and is made from hydrophobic oxide particles.SELECTED DRAWING: Figure 1
