| titleOfInvention | Early-strength viscosity-reduction type polycarboxylate superplasticizer containing double viscosity-reduction functional groups and preparation method thereof |
| abstract | The invention provides an early-strength viscosity-reduction type polycarboxylate water reducer, which is synthesized by the invention, and the components and functional groups of the early-strength viscosity-reduction type polycarboxylate water reducer have mutual synergistic effect. The water reducing agent has good effects of promoting cement hydration and improving the early strength development of concrete; the water reducing agent has good water reducing rate and slump retaining capacity. The early-strength and hydrophobic viscosity-reducing functional groups of the water reducer are positioned on the side chains, and the early-strength and viscosity-reducing effects of the water reducer can be adjusted by adjusting the content of the viscosity-reducing and early-strength functional groups, but the dispersing effect of the dispersing groups on cement particles is not influenced, and therefore the dispersing and water-reducing effects of the water reducer are not influenced. |
