The effect of limestone filler [LF], dolomite filler [DF], metakaolin [MK], and metaillite [MI] additives on the packing density of the binary blended cements were studied using of the water film thickness [WFT] and the optimal water demand [OWD]. The influence of these supplementary cementitious materials [SCM] on the flowability of cement pastes and mortars was analyzed and the compressive strength of mortars was discussed. The results indicate that the incorporation of these SCM on the packing density is highly related to the particle size distribution and the optimal addition of SCM to the blended cements, assures maximum packing density. The effects on flowability not only depend on packing density but of the surface area of particles and the addition of SCM enhance the compressive strength of the mortars.
