摘 要:研究了碳纳米管、钢纤维、碳纳米管+钢纤维对混凝土抗压强度和抗冲击性能的影响。结果表明:掺入碳纳米管和钢纤维均能提高混凝土的抗压强度;单掺钢纤维较单掺碳纳米管对混凝土抗冲击性能的提升效果更大;混掺碳纳米管与钢纤维混凝土的韧性和延性较单掺钢纤维混凝土得到再次提升;复掺1%钢纤维+0.30%碳纳米管对混凝土性能的增强效果最显著。
Abstract: The effects of carbon nanotubes, steel fibers, carbon nanotubes + steel fibers on the compressive strength and impact resistance of concrete were studied. The results show that the addition of carbon nanotubes and steel fibers can improve the compressive strength of concrete. Single-doped steel fiber has a greater effect on the impact resistance of concrete than that of single-doped carbon nanotubes. The toughness and ductility of concrete mixed with carbon nanotubes and steel fiber are improved compared with single-doped steel fiber concrete. Adding 1% steel fiber + 0.30% carbon nanotubes has the best reinforcement effect on concrete performance.
