摘要
文中通过干湿循环试验和微观试验,探究了赤泥对渣土基流动化回填材料水稳定性的影响。结果表明,20%赤泥部分替代水泥后,回填材料经历干湿循环后的强度损失最小。相较于普通回填材料,赤泥的添加有助于提高水化产物生成量,宏观表现为材料强度大,水稳定性好。
The influence of red mud on the water stability of mobile backfill material on muck foundation was investigated through dry and wet cycle test and microscopic test.The results show that the residual strength of the backfll material after dry and wet cycle are minimum and maximum when the cement is partially replaced by 20% red mud.Compared with the ordinary backfill material,the addition of red mud is helpful to improve the production of hydration products,which shows that the material strength is high and the water stability is good.
