中文摘要	研究了矿渣、粉煤灰、钢渣和石灰石粉这四种矿物掺合料对高强混凝土劈裂抗拉强度的影响差异。结果显示:矿渣对高强混凝土劈裂抗拉强度的贡献大于对抗压强度的贡献;粉煤灰对高强混凝土28 d劈裂抗拉强度的贡献略大于对抗压强度的贡献,随着龄期的增长,对劈裂抗拉强度的贡献明显增强;钢渣和石灰石粉对高强混凝土劈裂抗拉强度的贡献小于对抗压强度的贡献。; The influence of mineral admixtures including ground blast furnace slag,fly ash,steel slag,and limestone powder on the splitting tensile strength of high strength concrete was studied in this paper.The results show that the contribution of ground blast furnace slag to the splitting tensile strength of high strength concrete is higher than that to the compressive strength.The contribution of fly ash to the 28 d splitting tensile strength of high strength concrete is a little higher than that to the compressive strength,and it becomes much higher as hydration ages increase.The contribution of steel slag and limestone powder to the splitting tensile strength of high strength concrete is lower than that to the compressive strength.
