特性の制御が可能である。The hydraulic porous structure may be used undried or uncured. Regardless of whether it is undried, uncured, or cured, the material for filling the three-dimensional continuous ventilation holes of the hydraulic porous structure is changed from the material of the hydraulic porous structure 1 to the pores of the hydraulic porous structure. The material containing the hydraulic substance to be filled in the portion may be filled while being continuously changed. For example, by gradually changing the material of the slurry containing the hydraulic material, a functionally graded interface is formed at the interface between the hydraulic porous structure and the filling portion, which causes a difference in curing shrinkage or a difference in thermal expansion coefficient. It is possible to control mechanical properties such as reduction of strain near the interface.

Urethane foam was impregnated and adhered to this hydraulic slurry, and dried at room temperature. The dried body was a hydraulic porous structure having three-dimensional continuous pores, and its porosity was 83%. This hydraulic porous structure is immersed in a hydraulic slurry (slurry 2) prepared by thoroughly kneading 100 parts by weight of cement, 100 parts by weight of standard sand, and 50 parts by weight of water while defoaming under reduced pressure, and inside the pores. The slurry was filled in and then cured to obtain a hydraulic composite structure. The flexural strength of the obtained hydraulic composite structure on 28 days was measured to be 55 kg / cm.

状構造が相互に絡まった状態の構造でないためである。[Comparative Example 2] In order to perform an experiment in the case where the three-dimensional network structure of the hydraulic porous structure was destroyed and composited,
The dried porous hydraulic structure having a porosity of 83% obtained in Example 2 was pulverized and separated and recovered from the urethane foam, and the pulverized product and the hydraulic slurry used in Example 2 (slurry 2). Were mixed in the same ratio as in Example 1 to the slurry 1 and the slurry 2, and the urethane foam used in Example 1 was immersed in the obtained hydraulic slurry while defoaming under reduced pressure to form a slurry in the pores. And then cured to obtain a hydraulic composite structure. The flexural strength of the obtained hydraulic composite structure at 28 days was measured to be 40 kg /
cm 2 , which was lower than that in Example 2. This is because the network structure of the hydraulic porous structure having three-dimensional continuous air holes and the network structure of the hydraulic substance filled in the pores are not entangled with each other as in Example 2.
