| Abstract: | This paper discuss the effects of fly ash-ultra fine glass beads lightweight aggregates on the rheology, strength, quality homogeneity and density of cement slurries, and the working mechanism thereof. The aggregates can greatly improve the fluidity, water-keeping and the additive compatibility of cement slurries. Use this aggregate, the compressive and shear strengths of the set cement are also increased. Cement slurry treated with this aggregate has good quality homogeneity. |
