项目摘要

Reinforced concrete (RC) has been realized the reasonable structural system, but RC needs high performance against the durability caused by the corrosion of rebar. Also environmental performance should be needed in these days. Concrete has a limitation on these environmental performance because of the basic micro structure of concrete is a conventional inorganic materials, and it is important to add a property of organic such as plant which adapts itself to the global environment from ancient times incorporating a constant temperature, self recovery and a resistance against gravity by the cavity structure and the cellular system. In this study, we examined the effects such as conventional strength, stiffness, a constant temperature function (a heat island effect reduction, a planting effect) seen in organic matter, an air quality conversion function (harmful air quality reduction), the surface layer function (long life durability). As a result, (1) clarify the effect of the concrete containing water-absorbing resin component and the effect by the planting for the temperature constancy, (2) clarify a reduction effect of the carbon dioxide density that is the cause of the global warming and the reduction effect of room air pollutants such as the formaldehyde by using the cement system materials which gave air quality conversion action. (3) extension of service life by reforming the surface layer from the rebar corrosion, and clarified the fiber mixture to the surface layer and orientation effect by the magnetic force. These results have value for the sciences from the viewpoint of the building material science, and it is thought that the possibility as construction materials of the concrete can spread as for the significance in the future as well as an important to reduce of the environmental load as environmental symbiosis

钢筋混凝土（RC）已经实现了合理的结构体系，但RC需要高性能来抵抗钢筋腐蚀引起的耐久性。如今还需要环境绩效。混凝土在这些环境性能方面存在局限性，因为混凝土的基本微观结构是传统的无机材料，因此重要的是添加植物等有机物的特性，该特性自古以来就适应地球环境，包括恒温、自我恢复以及通过空腔结构和细胞系统抵抗重力。在本研究中，我们研究了有机物中的常规强度、刚度、恒温功能（减少热岛效应、种植效应）、空气质量转换功能（减少有害空气质量）、表面层功能（长寿命耐久性）等效果。结果，(1)明确了含有吸水性树脂成分的混凝土的效果以及通过种植对温度恒定性的效果，(2)明确了通过使用具有空气质量转换作用的水泥系材料来降低导致全球变暖的二氧化碳浓度的效果以及甲醛等室内空气污染物的降低效果。 (3)通过对钢筋腐蚀的表层进行改性，并通过磁力澄清纤维混合物对表层的定向作用，延长使用寿命。这些结果从建筑材料科学的观点来看具有科学价值，并且认为混凝土作为建筑材料的可能性能够得到普及，其未来的意义以及作为环境共生而对环境负荷的减轻具有重要意义。
