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系统，但是RC需要高性能与钢筋腐蚀引起的耐用性。这些天还应需要环境绩效。混凝土对这些环境性能有限制，因为混凝土的基本微结构是一种常规的无机材料，并且重要的是添加有机物的特性，例如植物，从远古时代开始适应全球环境，从恒定的温度，自我恢复，自我恢复和对腔体结构和蜂窝系统抵抗重力。在这项研究中，我们检查了在有机物中看到的诸如常规强度，刚度，恒定温度功能（热岛效应降低，种植效应），空气质量转换功能（有害空气质量降低），表面层功能（长寿命持久性）。结果，（1）阐明含有浸泡水的树脂成分的混凝土效果以及种植对温度恒定的影响，（（2）阐明二氧化碳密度的降低效果，这是全球变暖的原因，以及造成房间空气污染物的效果，例如使用构成甲基甲基甲基甲基甲基甲基甲基甲基甲基甲基甲基甲基甲基的效果，从而赋予了胶结质量的质量质量，从而使甲基甲基甲基的效果。 （3）通过从钢筋腐蚀中改革表面层来延长使用寿命，并将纤维混合物澄清到表面层和磁力方向效应。这些结果从建筑物材料科学的角度对科学具有价值，并且人们认为，作为混凝土建筑材料的可能性可能会在未来的重要性上传播，并且重要的是减少环境负荷作为环境共生的重要性
