| Outline of Research at the Start |
資源循環型社会の構築およびカーボンニュートラルへの貢献を目的として、地球素材である土を用いた建築材料の高度化に取り組む。すなわち、土ブロックの強度・耐久性・熱的特性の向上を図るための実験的・解析的研究を実施する。具体的には、NaOHの利用、および宜雄ポリマーとしての利用などを図るとともに、土ブロックの性能への土粒子の粒度分布の影響、化学成分の影響などを、レーザー回折式粒度分布計、X線回折分析装置、NMR装置などを用いて解析し、ニューラルネットワークなどを用いて、土ブロックに及ぼす土の各種特性の影響を明らかにし、最適な土ブロックの製造方法を提案する。

| Outline of Annual Research Achievements |
The research activities were mostly dominated by the training and monitoring activities in the BME laboratory. These included the radioisotope training programs, Cryogenic Research Canter Safety Training Program and Environment safety course as well. In the framework of the development of solid form of the geopolymer binders using the tropical soil, the characterization such as BET analysis and particle size measurement were performed for the laterite and clayey soils to optimize the mechanical activation synthesis condition. Chemical and mineralogical analysis are still ongoing.

Current Status of Research Progress
3: Progress in research has been slightly delayed.
Reason
The activities are still beginning through the characterization of the tropical soil samples. The start was shifted because after the elaboration of the experimental research plan, it was pointed out the needing of the training such as Environment, Health and Safety Program, Cryogenic research safety, and Radioisotope training programs. These allow me to fulfil the regulations of the University of Tokyo and foster my academic and scientific background.

| Strategy for Future Research Activity |
For the near future, the following activities will be conducted.
Part one is the synthesis of the low-energy alkali activated earth-based materials, and the aims include synthesis of the alternative binder using the mechanical activation of soils.
Activities in progress cover 1) chemical and mineralogical analysis of laterite and clayey soils, 2) mix-design of the alkali activated laterite and alkali activated clayey soils, 3) characterization, 4) data curation and analysis, and 5) writing of draft and preparation the paper presentations.
Activities in prospects cover 1) designing the lightweight earth-based materials for functional applications, 2) mix-design of the low-energy lightweight materials based on tropical soils (preparation of porous matrix using H2O2 as foaming), 3) optimization of synthesis conditions, and 4) characterization of the produced materials, and 5) data curation and analysis, and preparation the paper presentations.
