Abstract
In this study, usability of Basic Oxygen Process (BOP) slags of Kardemir Iron and Steel Plant, Karabük, Turkey as an additive into cement was investigated. Slags were ground to 4000 and 4700 cm 2/g levels, and added in ratios 15, 30 and 45 wt.%. Volume expansion, setting time, compressive strength and bending strength tests were measured according to Turkish standards. Due to impurities of the slags, the 2- and 7-day compression strengths decrease with increase in amount of Mn, but this decrease is lower in the 28-day compression strength, 30 wt.%. It is observed that the physical and mechanical properties of the resulting concrete were acceptable in the Turkish Standards Institute (TSE).
