摘要： 为研究碳化钢渣细骨料对混凝土性能的影响规律,对碳化钢渣进行物理化学试验,制备了普通混凝土及10%、20%及30%三种体积分数的碳化钢渣细骨料混凝土(carbonized steel slag fine aggregate concrete, CSSFC),研究碳化钢渣体积分数对混凝土力学性能及体积安定性的影响规律。结果表明:随着碳化钢渣细骨料体积分数由10%递增至30%,CSSFC的立方体抗压强度、劈裂抗拉强度、弹性模量及峰值应变均逐渐增大,普通混凝土轴心抗压强度与立方体抗压强度的比值为0.76~0.82,CSSFC的轴心抗压强度与立方体抗压强度的比值为0.85~0.87。研究了适用于CSSFC的本构关系模型,并分析模型拟合参数与力学性能间的关系,以期为钢渣混凝土的应用及推广提供试验及理论依据。
