本报では、ポルトランドセメントを使用しない超低収缩?高强度コンクリートの実用化を目的とし、火灾加热を受けた际の爆裂性状を确认した。ポリプロピレン繊维と钢繊维を所定量混入した供试体に対し材齢约3か月と1年において爆裂试験を実施し、材齢の経过が强度発现と爆裂性状に与える影响を确认した。実験の结果、繊维の混入により爆裂による损伤は低减された。また、爆裂による损伤は强度増进に伴い小さくなる倾向が得られた。 キーワード: 低环境负荷、耐火、爆裂、钢繊维、ポリプロピレン繊维 |

In this report, the explosion property under fire condition was investigated for the purpose of practical application of ultra-low shrinkage and high strength concrete without Portland cement. Explosion tests were carried out on small specimens containing a specified amount of polypropylene fiber and steel fiber at ages around 3 months or 1 year. From the test results, authors investigated as to the effect of strength gain to the explosion properties. As a result, the damage caused by the explosion was reduced due to containing fibers. It was also confirmed that the spalling was reduced due to compressive strength gain of concrete as well.
