摘要
介绍了添加絮凝剂的全粒级尾砂充填料强度试验,由试验得出了三个龄期的单轴抗压强度方程。试验结果表明,聚丙烯酰胺对各龄期强度均有不同程度的降低;硫酸铁与聚丙烯酰胺存在交互作用。
The strength of unclassified failing fills containing flocculants was tested and equations of uniaxial compressive strength for three curing periods were derived. The test results show that polyacrylamide can reduce the strength at varous periods to some degree, but freeous sulfate may act as a linking agent to polyacrylamide.
