PROBLEM TO BE SOLVED: To provide a placing method of concrete in which a cemented excelsior board can be used for a form without impairing the heat-insulation characteristic and the sound-absorbption characteristic of the board. SOLUTION: A cemented excelsior board 10 which is as thick as 30 mm or more and about 0.7 in a specific gravity and mixed with wooden chips of 5-8 wt.%, is used as a form. In this time, concrete can be placed as it is without use of reinforcing materials such as concrete panels, and the characteristics of the cemented excelsior board 10 can be brought out. The cemented excelsior board surface is filled with wooden chips by adding them, and lime wash is prevented from dripping down and further, erection and demolition is facilitated.
