Text description provided by the architects. For this project, we developed a 100% recyclable concrete which, instead of sand, contains SHIRASU, the deposit of pyroclastic flow of volcanic ash which is found in the Southern parts of Japan in abundance. The advantage of this concrete is its strength and durability that increases to grow over a long period of time because of the pozzolanic reaction of SHIRASU. Also its density, which comes from the fine granularity of SHIRASU, protects the concrete from neutralization. SHIRASU also contains micro closed-cells which gives the concrete humidity control and deodorizing qualities. This development and use of SHIRASU concrete can be a huge asset to those areas where SHIRASU can be excavated.
