Abstract:

© 2017, Editorial Board of Journal of Tianjin University(Science and Technology). All right reserved. The dynamic and static compressive experiments on ultra-high performance concrete(UHPC)were carried out, including five sets of specimens with different mixtures, by utilizing the 75 mm split Hopkinson pressure bar (SHPB) system and the YAW-3000 electro-hydraulic servo testing machine, respectively. The effects of types and volume ratios of steel fibers on dynamic compressive strength were analyzed in detail. The dynamic increase factors of UHPC for different mixtures were calculated and the diagram of dynamic increase factors was further obtained. The results indicate that the dynamic compressive strength and peak strain of the UHPC increase significantly with the increase of strain rates; the types and volume ratios of steel fibers have great effect on the dynamic properties of the UHPC but little effect on the dynamic increase factor; a better improvement effect of fibers with greater length-diameter ratios on the dynamic compressive strength of the UHPC was also clearly observed.
