Sažetak

Disposal of industrial waste materials such as cement Kiln dust, granulated ground blast furnace slag, and brick powder causes a nuisance in our environment. This research aimed to use these materials as partial cement replacement in production of self-compacting concrete having cement contents of 450 and 500 kg/m3 at ratios of 5%, 10%, 15%, and 20% of cement weight. Fresh and hardened properties were estimated in this study. Results showed that increasing filler materials content led to a significant improvement in fresh properties. On the other hand, hardened properties generally decreased with the addition of these minerals. Results indicated that relative splitting tensile/compressive strengths mostly did not exceed 0.09. Relative flexural/compressive strengths mostly exceeded 0.15 at cement content equalling 450 kg/m3. Relative splitting tensile/flexural strengths were less than 0.6 for most mixes.
