[Background Art] Research on warping and cranking of building materials, especially cement-based inorganic exterior materials, has been conducted for a long time. In particular, various studies have been made regarding cranks based on shrinkage of plate materials. According to these findings, stress is generated inside the board and at the parts where the building material is fixed by nails and the like due to the shrinkage of the material, and it is determined that this stress is the cause of warping and cracking. It also prevents shrinkage,
This is one of the countermeasures against warping and cranking, but even if stress occurs due to shrinkage, if the stress relaxation property is large, the shrinkage can be withstood. Most of the conventional techniques, like the former, are measures for preventing crack generation by reducing shrinkage, and there are few that utilize stress relaxation.
