Abstract: Lately, a great many studies for sustainable development have been fulfilled to research the use of waste materials as a construction material. The reutilise of lead-acid batteries smelting slag (LSS) as a construction material not only reduces disposal problems but has ecological and economic advantages as well. In this study, LSS is reutilised as partial cement replacements for making cement mortar. For this purpose of evaluating the effect of LSS on the compressive strength properties, the mortar mixtures containing 2%, 4%, 6%, 8% and 10% LSS as cement replacement are prepared, in addition, the leaching characteristics of the cement mortars designed by mixing cement with LLS are inspected at varied curing times such as 1, 2, 7 and 28 days. According to analysing findings, the compressive strength decreases as the replacement rate of LSS increased. The experimental results specify that the mixtures that are containing 8% LSS, compressive strength performance similar to the reference mixture. When the percentage of LSS is %10, the compressive strength is decrease. The leaching tests results are lower than the limits of TS EN 12457-4 and TCLP standards. This research shows that concrete is suitable for industrial slag problems.
