Process for producing dispersant for powdery hydraulic composition |
摘要 |
The present invention relates to a process for producing a powdery dispersant for preparing hydraulic compositions, which process includes adding an reducing agent to a solution predominantly containing a polycarboxylate polymer compound having a polyalkylene glycol chain, drying the resultant mixture, and pulverizing the dried product; the resultant powdery dispersant for preparing hydraulic compositions; and a hydraulic composition containing the dispersant. According to the present invention, there can be provided a powdery dispersant for preparing a hydraulic composition, which has excellent fluidity and dispersibility. The dispersant can be added to cement in advance.
