This work addresses the characterization of physical, chemical and mechanical properties of steel slag in the employment as an aggregate before and after controlled leaching test in Soxhlet extractor. The material was characterized before going through the stabilization process (virgin slag) and after controlled leaching in different periods of 24, 56, 96, 120 h. The steel slag was subjected in the laboratory to simulate the precipitation in Soxhlet equipment to evaluate its physical, chemical and mechanical properties after each period. The study of the leaching process in steel slag aimed to understand the influence of the washing process in the slag behavior. The virgin sample, without receiving stabilization process through controlled leaching, showed satisfactory results in the physical characterization when compared to conventional aggregates. After controlled leaching, the steel slag showed no significant loss of its physical properties. As for the mechanical expansion tests, there was a decrease of the expansibility potential, after leaching periods. It is concluded that the leaching process in a Soxhlet extractor is of importance in the study of the steel slag properties.

这项工作解决了在索氏提取器中进行受控浸出试验之前和之后，作为集料使用的钢渣的物理，化学和机械特性的表征。在经过稳定化处理（纯渣）之前和在24、56、96、120小时的不同时间进行受控浸提后，对材料进行了表征。在实验室中对钢渣进行了模拟，以模拟索氏提取器中的沉淀，以评估每个时期后的物理，化学和机械性能。对钢渣浸出过程的研究旨在了解洗涤过程对渣行为的影响。原始样品没有通过受控浸提进行稳定处理，与常规骨料相比，在物理表征方面显示出令人满意的结果。在控制浸出后，钢渣没有表现出明显的物理性能损失。至于机械膨胀试验，浸出期后，可膨胀性降低。结论是，在索氏提取器中的浸出过程对钢渣性能的研究很重要。
