339-344In this study, the use of steel
slag as fine and/or coarse aggregate in concrete is investigated. For this
purpose,
12 different concrete mixtures with different water/cement ratios of 0.40, 0.55
and 0.70 which include steel slag aggregate as fine and/or coarse aggregate are
prepared. Compressive strength, split tensile strength, flexural strength,
freeze-thaw resistance and water penetration depth of concrete mixtures
containing steel slag aggregate are examined in comparison with concrete
mixtures prepared by using crushed limestone aggregate. Eventually, concrete
mixtures containing coarse steel slag show better performance than concrete
mixtures containing limestone aggregate. Concrete mixtures containing fine
steel slag show worse performance in comparison with concrete mixtures
containing limestone aggregate.
