Effects of coarse aggregate content and particle size on mechanical properties of ultra-high performance concrete (UHPC) with river sand as a coarse aggregate replacing quartz sand were investigated. The results show that the cube compressive strength and axial compressive strength of UHPC matrix are obtained at the coarse aggregate filling content of less than 400 kg/m3. The cube compressive strength and axial compressive strength decrease when the filling content of coarse aggregate further increases. The increase of particle size of coarse aggregate has a strengthening effect on the cube compressive strength and axial compressive strength of UHPC matrix, while the particle size of coarse aggregate has little effect on the UHPC flexural and splitting tensile strength. The UHPC initial crack strength, peak strength, initial crack deflection, peak deflection and energy dissipation decrease slowly with the increase of coarse aggregate filling content. The strength and energy dissipation in each stage decrease with the increase of particle size of coarse aggregate, while the initial crack deflection and peak deflection have a slow increasing trend with the increase of particle size of coarse aggregate, and the toughness index decreases gradually with the increase of aggregate filling content and particle size.

采用河砂替代石英砂并添加粗骨料的方式制备含粗骨料的超高性能混凝土（UHPC），研究不同粗骨料掺量和粒径对UHPC力学性能的影响。结果表明：粗骨料掺量的增加对UHPC基体新拌混合物的流动性具有降低作用，粗骨料粒径对新拌混凝土的流动性具有不规则增强效应；当粗骨料掺量不大于400 kg/m3时，UHPC基体立方体抗压强度和轴心抗压强度呈现不同程度的增长，当粗骨料掺量继续增加，UHPC基体立方体抗压强度和轴心抗压强度出现下降；粗骨料粒径的增加对UHPC基体的立方体抗压强度和轴心抗压强度具有增强效应，而对UHPC抗折及劈裂抗拉强度影响不大。骨料掺量对UHPC基体的弹性模量具有增强效应，骨料粒径越小，弹性模量越大；UHPC初裂强度、峰值强度、初裂挠度、峰值挠度以及各阶段耗能均随粗骨料掺量的增加缓慢降低；初裂强度、峰值强度、各阶段耗能均随粗骨料粒径的增大而降低，初裂挠度与峰值挠度随粗骨料粒径的增加呈现缓慢上升的趋势；韧性指数I5、I10、I20均随骨料掺量和粒径的增加而逐渐减小。

摘要
收起

采用河砂替代石英砂并添加粗骨料的方式制备含粗骨料的超高性能混凝土（UHPC），研究不同粗骨料掺量和粒径对UHPC力学性能的影响。结果表明：粗骨料掺量的增加对UHPC基体新拌混合物的流动性具有降低作用，粗骨料粒径对新拌混凝土的流动性具有不规则增强效应；当粗骨料掺量不大于400 kg/m3时，UHPC基体立方体抗压强度和轴心抗压强度呈现不同程度的增长，当粗骨料掺量继续增加，UHPC基体立方体抗压强度和轴心抗压强度出现下降；粗骨料粒径的增加对UHPC基体的立方体抗压强度和轴心抗压强度具有增强效应，而对UHPC抗折及劈裂抗拉强度影响不大。骨料掺量对UHPC基体的弹性模量具有增强效应，骨料粒径越小，弹性模量越大；UHPC初裂强度、峰值强度、初裂挠度、峰值挠度以及各阶段耗能均随粗骨料掺量的增加缓慢降低；初裂强度、峰值强度、各阶段耗能均随粗骨料粒径的增大而降低，初裂挠度与峰值挠度随粗骨料粒径的增加呈现缓慢上升的趋势；韧性指数I5、I10、I20均随骨料掺量和粒径的增加而逐渐减小。

Effects of coarse aggregate content and particle size on mechanical properties of ultra-high performance concrete (UHPC) with river sand as a coarse aggregate replacing quartz sand were investigated. The results show that the cube compressive strength and axial compressive strength of UHPC matrix are obtained at the coarse aggregate filling content of less than 400 kg/m3. The cube compressive strength and axial compressive strength decrease when the filling content of coarse aggregate further increases. The increase of particle size of coarse aggregate has a strengthening effect on the cube compressive strength and axial compressive strength of UHPC matrix, while the particle size of coarse aggregate has little effect on the UHPC flexural and splitting tensile strength. The UHPC initial crack strength, peak strength, initial crack deflection, peak deflection and energy dissipation decrease slowly with the increase of coarse aggregate filling content. The strength and energy dissipation in each stage decrease with the increase of particle size of coarse aggregate, while the initial crack deflection and peak deflection have a slow increasing trend with the increase of particle size of coarse aggregate, and the toughness index decreases gradually with the increase of aggregate filling content and particle size.
