Özet:

In this study, surface interaction mechanisms of the portland cement (OPC) and trass blended cements (TC) were investigated. The physical, chemical, mineralogical and mechanical properties of OPC, trass and TC, as well as the electrokinetic potantials (zeta potantial) of trass-PÇ particles were examined. After cement pastes were prepared with OPC and trass, they were water-cured for 2, 7 and 28 days. The pastes were made using XRD, DTA-TG and FT-IR in order to determine their mineralogical composition and the determination of the phases developed during the hydration. Furthermore by SEM 28-day microstructures of pastes were determined and mortars were examined following strength tests. Trass has shown different electrokinetic behaviours and surface features compared to OPC. These variations effected on compressive strenght of mortar samples.
