Research on the Flexural Behavior of Waste Tire Ultra-high Performance Concrete
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.
