<P>PROBLEM TO BE SOLVED: To provide a lining sheet to be attached to a concrete form for use in dehydration and defoaming, which has excellent portability and can be easily attached without the occurrence of wrinkles. <P>SOLUTION: A lining sheet 10 for a concrete form, which is attached to the inner side of a form panel for use, comprises a porous nonwoven fabric sheet 15 permeable to water and air and nonpermeable to concrete particles and a fine-mesh net 12 having self-supporting rigidity. The nonwoven fabric sheet 15 and the net 12 are laminated to form the lining sheet. The nonwoven sheet 15 is a sheet which is manufactured from synthetic resin fiber by a wet paper making method. The net 12 is manufactured from a synthetic resin material having a melting point lower than the melting point of the synthetic resin material of the nonwoven fabric sheet 15. <P>COPYRIGHT: (C)2013,JPO&INPIT |
