Abstract: Adopt the chemical method，carry on the saponification to the lignin sulfonic acid calcium，and compound with the surface-active agent.This admixture can totally replace lime，improving apt and cohesiveness of mortar，having the function of holding water，reducing water and improving the early strength.In this way，it can reduce the cost of extra agent greatly and widen the range of application of lignin sulfonic anid calcium
