摘 要:为了研究碳纳米管(CNTs)在超高性能混凝土(UHPC)中的分散效果及其对UHPC力学性能的影响,进行了不同CNTs掺量UHPC的动力黏度、抗压强度和抗折强度试验。结果表明:CNTs在UHPC基体中的分散效果随着CNTs掺量的增加而不断变差,且会导致较高CNTs掺量的UHPC力学性能降低;当CNTs掺量为0.1%时,CNTs增强UHPC的力学性能最佳。
Abstract: In order to study the dispersion effect of carbon nanotubes(CNTs) in ultra-high performance concrete (UHPC) and its influence on the mechanical properties of UHPC, shear viscosity, compressive strength and flexural strength of UHPC with different CNTs content were tested. The results show that the dispersion effect of CNTs in UHPC matrix deteriorates with the increase of CNTs content, and the mechanical properties of UHPC decrease with the increase of CNTs content. When the CNTs content is 0.1%, the mechanical properties of UHPC are the best.
