摘 要:研究了纳米SiO2和PVA纤维掺量及掺入方式对再生混凝土(RAC)力学性能与抗冲击性能的影响。结果表明:掺入纳米SiO2和PVA纤维均可以显著提高RAC的抗冲击性能;当混掺0.075%的PVA纤维与1.0%纳米SiO2时,RAC抗压强度与抗冲击性能的提高幅度最显著。
Abstract: The influence of the content and blending method of nano-SiO2 and PVA fiber on the mechanical properties and impact resistance of recycled concrete (RAC) was studied. The results show that the impact resistance of RAC can be significantly improved by adding nano-SiO2 and PVA fiber. When 0.075% PVA fiber and 1.0% nano-SiO2 are mixed, the improvement of the compressive strength and impact resistance of RAC is the most significant.
