摘　　要：以机械活化钒尾矿、复合活化钒尾矿、粉煤灰、硅酸盐水泥为原材料制备矿山充填材料,研究了水泥用量、粉煤灰用量、料浆浓度(质量分数,下同)和养护时间等因素对样品抗压强度的影响。结果表明,当机械活化钒尾矿、复合活化钒尾矿、粉煤灰与水泥质量比为45∶15∶10∶30,料浆浓度为76%时,样品养护28 d后抗压强度可达17.8 MPa。Using mechanically activated vanadium tailings,composite activated vanadium tailings,fly ash and Portland cement as raw materials,the effects of cement dosage,fly ash dosage,slurry concentration and curing time on the compressive strength of samples were studied.The results showed that,When the mechanical activated vanadium tailings,composite activated vanadium tailings,fly ash and cement mass iatio of 45∶15∶10∶30 and the slurry concentration is 76%,the compressive strength of the sample after curing for 28 d can reach 17.8 MPa.
