摘要
传统超高性能混凝土包含大量水泥和钢纤维,其生产过程会产生较高的碳足迹.为减小碳足迹,文中利用废旧轮胎的橡胶及钢纤维分别作为部分细骨料和增强纤维,以矿渣-粉煤灰替代水泥,提出了废旧轮胎超高性能混凝土(T-UHPC),对含有不同橡胶粉末替代率的T-UHPC进行抗压和抗弯试验,分析了橡胶粉含量对抗压和抗弯性能指标的影响规律.
Abstract
Due to the fact that traditional Ultra-high performance concrete contains a large amount of cement and steel fibers,its production process will generate a high carbon footprint.In order to reduce the carbon footprint of UHPC,Waste Tire UHPC(T-UHPC)was proposed by comprehensively utilizing the rubber and steel fibers crushed from waste tires as part of the fine aggregate and reinforcement fibers,and repla-cing cement with slag-fly ash based geopolymer.Compressive and flexural tests were conducted on T-UHPC containing different crumb rubber replacement ratios,and the effects of crumb rubber content on compressive and flexural performance indicators were analyzed.
