Outline of Final Research Achievements

New attractive applications of HPFRCCs (High Performance Fiber Reinforced Cementitious Composites) were investigated.
Lightweight HPFRCCs containing EPS (Eexpanded Polystyrene) particles were proposed. Unique specimen-drop tests were performed on six-legged specimens made of lightweight HPFRCCs etc. assuming concrete blocks that are drop-deposited to form an erosion control structure in the mountains. The steel-bar reinforcement and the reduction of mass of specimens were beneficial for enhancing the impact resistance performance of falling specimens.
Long-term ASR(AlkaliSsilica Reaction)-expansive HPFRCCs were developed. Chemical prestress was introduced into this material by restraining the ASR expansion using reinforcing bars. Reinforced ASR-expansive HPFRCC beams showed higher cracking strength due to the chemical prestress.
