SIZE EFFECT OF MEMBERS ON FLEXURAL/TENSILE STRENGTH OF HARDENED HIGH-TOUGHNESS ECO-BINDER（HTEB）AND IMPACT RESISTANCE OF HTEB PANEL TO REPEATED DROP-WEIGHT IMPACT

高靱性エコバインダー（HTEB）硬化体の曲げ・引張強度に及ぼす部材の寸法効果およびHTEBパネルの繰返し落錘衝撃に対する耐衝撃性

High-toughness eco-binder (HTEB), in which polyethylene short fibers are mixed into binder composed of three components（blast furnace slag, gypsum dihydrate, and calcium hydroxide), has been developed by the authors. In this study, to investigate the applicability of the HTEB to panel members, experimental investigations were conducted regarding size effect of members on flexural/tensile strength of the hardened HTEB and impact resistance of bamboo-reinforced HTEB panel against repeated drop-weight impact. As a result, the authors quantitated the size effect of members based on the concept of highly stressed volume, and it was also shown that the bamboo-reinforced HTEB panel possessed good impact resistance as compared with conventional reinforced concrete panel.高炉スラグ微粉末、二水石膏および水酸化カルシウムから成る3成分系結合材にポリエチレン短繊維を混入した高靱性エコバインダー（HTEB）の開発を進めている。本研究では、HTEBのパネル部材への用途開発に資するため、HTEB硬化体の曲げ・引張強度に及ぼす部材の寸法効果および竹筋補強HTEBパネルの繰返し落錘衝撃に対する耐衝撃性について実験的検討を行った。その結果として、高応力域体積の概念に基づきHTEB硬化体の曲げ・引張強度に及ぼす部材の寸法効果を定量化するとともに、竹筋補強HTEBパネルが通常の鉄筋コンクリートパネルに比して非常に良好な耐衝撃性を有していることを実験的に明らかにした。
