摘要

从报废轮胎中获得的纤维增强混凝土在高压缩应变速率下的性能是本研究的范围。使用直径为40mm的霍普金森压杆进行实验室研究。将具有非典型几何参数的废弃纤维以30kg/m3的剂量应用于混凝土。当受到高应变速率时，观察到RSFRC的抗压强度显著增加。DIF表达的RSFRC的应变速率敏感性与文献中给出的其他结果相当。

Behavior of Concrete Reinforced with Fibers from End-of-Life Tires Under High Compressive Strain Rates

The behavior of concrete reinforced with the fibers obtained from the end-of-life tires under high compressive strain rates was the scope of this research. The laboratory investigations were performed using the Hopkinson Pressure Bar with a diameter of 40 mm. The waste fibers with untypical geometrical parameters were applied to concrete with a dosage of 30 kg/m3. The pronounced increase of compressive strength of the RSFRC, when subjected to high strain rates, was observed. The strain rate sensitivity of the RSFRC expressed by DIF was comparable to the other results presented in the literature.

期刊介绍： Engineering Transactions (formerly Rozprawy Inżynierskie) is a refereed international journal founded in 1952. The journal promotes research and practice in engineering science and provides a forum for interdisciplinary publications combining mechanics with: Material science, Mechatronics, Biomechanics and Biotechnologies, Environmental science, Photonics, Information technologies, Other engineering applications. The journal publishes original papers covering a broad area of research activities including: experimental and hybrid techniques, analytical and numerical approaches. Review articles and special issues are also welcome. Following long tradition, all articles are peer reviewed and our expert referees ensure that the papers accepted for publication comply with high scientific standards. Engineering Transactions is a quarterly journal intended to be interesting and useful for the researchers and practitioners in academic and industrial communities.
