| description | The embodiment of the invention discloses an ultra-long slump-retaining polycarboxylic acid water reducing agent and a preparation method thereof. The polycarboxylic acid water reducing agent comprises 8-30% of water reducing mother liquid, 8-30% of slump-retaining mother liquid, 1-5% of internal curing adjusting liquid and the balance of water. The polycarboxylate superplasticizer provided by the invention takes the autonomously synthesized water reducing mother solution, the slump retaining mother solution and the internal curing adjusting solution as raw materials, the water reducing rate of the water reducing mother solution can reach 45-46%, and the adaptability is strong; the slump retaining mother liquor has long-time slump retaining capacity (3-5 hours); and the internal curing adjusting liquid can improve the workability of the concrete and has a film-forming property. The water reducing agent provided by the invention has the properties of high water reducing rate, long-time slump retaining, interna |
