摘要
为研究铁尾矿球替代粗骨料对透水混凝土性能的影响规律,制备普通透水混凝土和替代率分别为25%、50%、75%和100%的铁尾矿球透水混凝土,对其进行抗压强度试验、劈裂抗拉强度试验和透水系数试验。结果表明随着铁尾矿球替代率的增加,抗压强度和劈裂抗拉强度呈减小、增大再减小的变化趋势,透水系数呈增大、减小再增大的变化趋势。
To study the effect of iron tailings ball replacing coarse aggregate on the macroscopic properties of permeable concrete, the concrete with replacement rates of 25%, 50%, 75% and 100% of iron tailings ball were prepared.The compressive strength, splitting tensile strength, and permeability coefficient were measured. The results show that with the increase of replacement rate of iron tailings balls, the compressive strength and splitting tensile strength first decrease, then increase, and decrease;the permeability coefficient first increases, then decreases, and increases.
