Toughness tests for waste tires steel fiber reinforced concrete
GAO Lingling
Abstract：In order to research the application prospect of waste tires steel fiber reinforced concrete in road engineering,the effect of waste tires steel fiber and ordinary steel fiber on toughness of cement concrete were determined using ASTM C1018. The results show that:the waste tires steel fiber has a significant enhancement effect on the toughness of concrete. With the increase of the steel fiber dose,the loading-deflection curve after initial cracking is fuller,the secondary peak of the load is increasing,and the concrete is getting closer to the ideal elastic-plastic material. The toughness of waste steel fiber reinforced concrete is lower than that of ordinary steel fiber. To achieve the same toughness index,the dose of waste tires steel fiber required to be about 25%~45% higher than ordinary steel fiber.
