ABSTRACT
Based on performed research in this paper the evaluation of the effect of selected quartz mineral admixtures applied in added concrete on their adhesion to concrete substrate was presented. These admixtures were quartz and feldspar-quartz mineral used in varying amounts relative to the weight of cement. Research performed by pull-off method presents that feldspar-quartz mineral powder definitely affects adversely on that adhesion.
