Resumen:
The effect of limestone fi ller [LF], dolomite fi ller [DF], metakaolin[MK], and metaillite [MI] additives on the packing density of thebinary blended cements were studied using of the water fi lm thickness [WFT] and the optimal water demand [OWD]. The infl uenceof these supplementary cementitious materials [SCM] on the fl owability of cement pastes and mortars was analyzed and the compressive strength of mortars was discussed. The results indicatethat the incorporation of these SCM on the packing density is highlyrelated to the particle size distribution and the optimal addition ofSCM to the blended cements, assures maximum packing density.The effects on fl owability not only depend on packing density butof the surface area of particles and the addition of SCM enhancethe compressive strength of the mortars.
