ABSTRACT:
A water-retainable molding is formed by mixing and hardening cement, fiber bundles and fiber masses, and includes first pores inside the fiber bundles, second pores between fiber bundles and a cement gel, third pores inside the fiber masses, fourth pores between the adjacent fiber masses, and fifth pores due to discharge of water content and air inside a platelike block. The first, second and fifth pores are employed as a capillary portion, the third pores are employed as a water-retaining portion, and the fourth pores are employed as a water communicating opening portion. When water is supplied to the surface, the water is absorbed from the fourth pores as well as the first, second and fifth pores, and is retained in the third pores. Furthermore, when the temperature rises, the water content is supplied from the third pores to the surface through the first, second and fifth pores so as to be evaporated and to control the temperature of the molding.
