A new method for the mix design of medium strength

2003-2-1  This paper proposes a new mix design method for medium strength flowing concrete (FC) with low cement content. The proposed method determines the packing factor (aggregate content) first, and then fills binding paste containing fly ash and GGBS into the voids between aggregates to make concrete that has the desired workability and strength.
