| 摘 要： | 通过室内冻融循环试验,对无机结合料稳定铁尾矿砂的抗冻融耐久性进行了试验研究。得到了失重率和残留强度比随冻融循环次数的变化规律,并与石灰土的结果进行了比较。结果表明:随冻融循环次数的增加,四种混合料的质量损失逐渐增加,残留强度比逐渐减小,但是变化的速度却相差很大。由此说明,无机结合料稳定铁尾矿砂的抗冻融耐久性远远好于石灰土,其中水泥稳定铁尾矿砂的抗冻融性能较为突出。

| Abstract: | Durability of freezing-thawing resistance of inorganic binders stabilized iron tailings with the optimal ratio were studied by indoor test.The variation of weightlessness rate and tensile strength ratio with freezing-thawing cycles were obtained.The comparisons to that of soil-lime were also made.It shows that the mass losses of the four mixture were increasing as the same time tensile strength ratio was decreasing gradually with freeze-thaw cycles,but the pace of the variations of the four mixtures was a g... |
