| Outline of Final Research Achievements |
As a result of this study, the utilization method of Moso bamboo to cementitious composite system was established. A mix design method considering the water content of Moso bamboo was proposed. In this study clarifies the effect of moisture content and mixing quantity of Moso bamboo on various performances of fiber reinforced porous concrete and water-retentive cement filler system. In addition, it was confirmed that the use of Moso bamboo, which has a high water absorption rate, in the water-retentive pavement material system was effective in suppressing the rise in road surface temperature.

| Academic Significance and Societal Importance of the Research Achievements |
生育スピードが早く地域の貴重な資源となり得る孟宗竹であるが、その利用は限定的で木質バイオマス発電への利用等に留まっている。本研究の成果は、セメント系複合材料の各種性能に与える孟宗竹の含水状態および混入量の影響を明らかにしたことで、大量利用が見込める土木用途での活用方法を見出した点にあり、地域資源の新たな循環システムに組み込まれることが期待される。
