摘要：为解决减水剂与增稠剂之间的相容性问题，研发了一种含有增稠组分的新型稳定剂，研究了其对水泥基材料的流变性能、流动性、力学性能的影响，并分析了微观结构。结果表明：新型稳定剂与减水剂具有较好的相容性，相比于单掺减水剂的拌和物，复掺新型稳定剂的拌和物屈服应力和塑性黏度降低，扩展度和力学性能增加，拌和物未出现泌水，具有较好的均质性和稳定性，且微观结构相对致密。 Abstract: To solve the compatibility issue between water reducing agents and thickeners, a new type of stabilizer with thickening components was developed. The effects of this stabilizer on the rheological, flowability, and mechanical properties of cement-based materials were studied, and the microstructure was analyzed. The results show that the new stabilizer has good compatibility with the water reducing agent. Compared to the mixture with single addition of water reducing agent, the mixture with a combination of the new stabilizer reduces the yield stress and plastic viscosity, increases the expansion and mechanical properties, and does not show bleeding. The mixture has good homogeneity and stability, and the microstructure is relatively dense.
