摘　　要：研究了单掺黄磷渣粉、复掺黄磷渣粉和硅灰对水泥浆体流变特性的影响。结果表明,随着黄磷渣粉掺量的增加,水泥浆体流动度增大,黏度和屈服应力降低,表现出剪切变稀的现象。掺入硅灰减小了浆体的流动度,提高了屈服应力和黏度;随着硅灰掺量的增加,复掺黄磷渣粉和硅灰浆体由剪切变稀向剪切变稠转变。黄磷渣粉和硅灰对浆体的流动性和流变性能的作用效果相反,硅灰对浆体的作用效果高于黄磷渣粉。The effects of single addition of yellow phosphorus slag powder,combined addition of yellow phosphorus slag powder and silica fume on the rheological properties of cement paste were studied.The results showed that with the increase of yellow phosphorus slag powder,the fluidity of cement paste increased,and the viscosity and yield stress decreased,showing the phenomenon of shear thinning.The addition of silica fume reduced the fluidity of cement paste and increased the yield stress and viscosity.With the increase of silica fume content,the mixed yellow phosphorus slag powder and silica fume changed from shear thinning to shear thickening.The effect of yellow phosphorus slag powder and silica fume on the fluidity and rheological properties of the cement paste was opposite,and the effect of silica fume on the cement paste is higher than that of yellow phosphorus slag powder.
