| Research Abstract |
"High performance fiber-reinforced cementitious composite with multiple fine cracks" (HPFRCC) is a watertight material because the cracks are narrow. In this study, the water-tightness of HPFRCC was further improved by filling seaweed gel (calcium alginate gel) into the fine cracks. The HPFRCC splayed on a concrete retaining wall was observed over 5 years. The crack width in the HPFRCC was mostly limited to not more than 0.1 mm. Special blocks, which are capable of having large deformation due to slide of structures during a huge earthquake, were fabricated using HPFRCC.
