| 摘 要： | 研究了聚合物对超细水泥浆体工作性能的影响,探讨了聚合物改性超细水泥灌浆材料的水化硬化程度.结果表明:当P/C 15%时,聚合物本身具有的自分散性能和表面活性减小了改性超细水泥浆体屈服应力τ0和塑性粘度η0,使得流动速率B和灌入量qb增加,从而显著地改善了超细水泥浆体的可灌性.

| Abstract: | Emulsion of polymer acrylate was chosen to modify the workability of the grout prepared with ultrafine cement and measurements were conducted to confirm the variation occurred in the paste due to the modification,i.e.the changes in viscosity,groutability,setting,hydration and rigidification.The result showed that the dispersion forces between the polymer molecules and surface activity caused appreciable decrease in the yield stress and plastic viscosity of the paste.as the mass ratio of polymer to cement ex... |
