Paper Title:
Effects of Packing Density of Micropowders on the Compressive Strength of Cement Pastes
  Abstract

This study was performed to evaluate the effects of micropowders content on the compressive strength of cement-based composite pastes. Granular ground blast slag (GGBS), grade I fly ash (FAI), ultra fine fly ash (UFA) and silica fume (SF) were selected as the micropowders. The compressive strength was tested after 3d, 7d and 28d curing. Results show that the paste containing both UFA and SF has the highest packing density and corresponding excellent compressive strength. The higher the packing density is, the better the compacting and filling effect of micropowders will be, which contributes to developing higher compressive strength of cement-based pastes.
