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

钢筋混凝土已经实现了合理的结构体系，但钢筋混凝土对钢筋锈蚀引起的耐久性要求很高。此外，在这些日子里，应该需要环保表现。混凝土的这些环境性能是有限的，因为混凝土的基本微观结构是一种常规的无机材料，重要的是增加有机的性质，如植物，从古代起就适应全球环境，通过空腔结构和蜂窝系统结合恒温、自我恢复和抗重力能力。在这项研究中，我们考察了常规强度、刚度、有机物中的恒温功能(减少热岛效应、种植效应)、空气质量转换功能(有害空气质量降低)、表层功能(长寿命耐用性)等影响。因此，(1)阐明了含吸水树脂组分的混凝土对温度恒定的影响，(2)阐明了引起全球变暖的二氧化碳浓度的降低效应，以及具有空气质量转换作用的水泥体系材料对室内空气污染物(如甲醛)的降低作用。(3)从钢筋锈蚀的表面层改造来延长使用寿命，明确了纤维混合物对表面层的作用和磁力的取向效应。从建材科学的角度来看，这些结果具有科学价值，认为混凝土作为建筑材料的可能性可以推广到未来的意义，以及作为环境共生而减少环境负荷的重要意义。
