摘要
本文介绍了外加剂的定义、分类及应用概况，并通过分析水泥水化过程和胶结充填掺用木钙的正交试验，揭示了外加剂在胶结充填中的作用机理，为减少水泥用量，降低充填成本，提供了一种思路．
The definition, classification and applied situation of admixtures are introduced. Their mechanism in cement filling is revealed by analysing the course of the cement hydration and the orthogonal test of adding calcium lignosulphonate.A new way is advanced for decreasing the amount of cement and reducing the cement filling cost.
