Abstract

In Japan, sufficient consideration is required for the natural ecosystem and landscape in the plan of river revetment. The current Rivers Act, in which the environment was recently added to conventional flood control and water use as an objective of river management, was applied in 1997. Furthermore, the basic guideline of Nature-oriented River Management was presented in 2006, and the good environment of rivers was recovered from river planning, considering the natural ecosystem and landscape, and the relationship between man and river would be rebuilt. Due to the backgrounds has mentioned above, river revetments using porous concrete have been focused on. Porous concrete is green concrete in which plant roots, water, and air can pass through the pores, and organisms can grow. It is required to have the strength necessary for safety as a revetment and have many pores. In this study, when the condition of “Low cost” was added to these conditions, hydroxyapatite (FbP) of the fishbone derivation was noticed to clear all these conditions. Also, physical property (strength, permeability, and porosity) tests and western turf grass growth tests are carried out for the FbP mixed porous concrete. According to the test results, the target values for the physical properties of the FbP mixed porous concrete are achieved. Furthermore, the FbP has a function to improve the plant growth environment of porous concrete since the leaf length of the germinated western turf in the FbP mixed specimens is longer than that in the non-FbP mixed specimens.
