Abstract (en)
[origin: WO0056509A1] An air-permeable protective fabric (4) for casting concrete in a form, the form consisting or flat form boards (1) having a front (3) to be directed towards the concrete (2) and a back (5) to be directed away from the concrete (2), is adapted to be arranged between the form and the concrete (2) to permit air from the concrete (2) to migrate through the fabric (4) and further along this into the open air. The protective fabric (4) is a hygroscopic fibre cloth, which is made of fibres of a plastic material, such as polyester or polypropylene, which by hot rolling has been given a certain, limited degree of stiffness and pits in the side facing away from the concrete (2). The protective fabric (4) has a defined thickness, preferably in the range 0.8 - 1.2 mm, thereby being sufficiently pliable and flexible to be folded round the edges (4a) of the form board (1) and be stretched to abut against the front (3), edges (4a) and back (5) of the form board (1).
