Abstract C-LTD80 QC rotary viscometer and Zeta were used to study the rheological behavior of natural pozzolan-cement-fly ash composite slurry. The effect of natural pozzolan content on the yield stress, plastic viscosity and thixotropy of the slurry were analyzed. On the other hand, the mechanism of action was explored by Zeta potential meter. The results show that the rheology of natural pozzolan-cement-fly ash composite slurry can be simulated by the Bingham model and the Herschel-Bulkley model together. Natural pozzolan has a large particle size distribution and irregular particle shape, and its density is less than cement. When equal mass is replaced, it will increase the volume fraction of the solid phase of the slurry; natural pozzolan reduces the Zeta potential of the cement slurry and weakens the electrostatic force between the particles in the slurry.The particles are easier to adsorb, cohesive with each other. The fly ash particles are spherical and have a smooth surface, which reduces the Zeta potential of the cement paste, and the particles are not easy to adsorb and agglomerate each other. Therefore, the yield stress, plastic viscosity and thixotropy of natural pozzolan-cement-fly ash composite slurry increase with the increase of natural pozzolan content, and decrease with the increase of fly ash content.

Key words： natural volcanic ash natural pozzolan-cement-fly ash composite slurry rheology Zeta potential
