In this study, the effect of mineral admixture utilization on fresh and
some hardened state properties of cement paste and mortar mixtures were
investigated. For this purpose, in addition to the control mixture containing
no mineral admixture, three more series of mixtures were prepared. In the first
and second mixtures 30% and 10 w.t% of cement was replaced with silica fume and
fly ash respectively. In the third series, cement was replaced with both of
silica fume and fly ash by 30% and 10%, respectively. According to test
results, fresh state properties of paste mixtures were affected by mineral
admixture use positively in general. However, a reverse result was observed for
the fresh state properties of mortar mixtures. Compressive strength values of
the mixtures including fly ash as well as the ones including silica fume and
fly ash was found to be less than that of control mixture. Nevertheless, the
difference between those values reduced at the end of 90 days. Mixture
including silica fume showed the highest strength value from the beginning.
90-day water absorption values of the mortar mixtures were observed to be less
compared to that of control mixtures with the use of mineral admixture. The
mixture having ternary binder system (including cement, silica fume and fly ash)
showed better performance in terms of hardened properties. The water absorption
capacity value of mentioned mixture was observed as 42% less than that of
control mixture.
