Abstract: PURPOSE: A concrete form with a debubbling function using water-shielding is provided to easily remove air bubbles remaining in concrete after compaction by letting the air bubble flow to the outside along the water-shielding fiber. CONSTITUTION: A concrete form with a debubbling function comprises water-shielding fiber(20) which passes vapor and gas, not water, because the fiber gap is smaller than water droplet and larger than vapor. The water-shielding fiber is made of gore-tex and placed on the surface of a form body(10) where concrete(30) is placed.
