Abstract

In this study, the effects of admixture types and admixture ratios on the durability properties of same strength class blended cements cured different environmental conditions were investigated. For this purpose, 3 types pozzolanic materials (blast furnace slag, fly ash, trass) were replaced with Portland cement by using 9, 14 and 19 wt.%. Thus, 9 types of blended cements and control cement without admixture having 350 m2/kg-370 m2/kg Blaine fineness were produced. Pozzolanic materials were accomplished in a laboratory mill by separate grinding technique. Plain and blended cement mortar specimens were stored under three different conditions: (i) continuous curing in water, (ii) after the 28th day of production, cyclic exposure wetting-drying and (iii) after the 28th day of production, cyclic exposure freezing-thawing. Experimental results showed that the freeze-thaw durability of the reference cement was better than the rest of the specimens. The blended cements containing trass performed poorly. However, the specimens containing slag and fly ash performed consistently well when exposed to freeze and thaw conditions. The cement containing 9% fly ash exhibited an increase in ultrasonic pulse velocity (UPV). The weight and UPV values of the specimens were not reduced under the wetting-drying effect.
