    摘要:

    钢渣集料物理力学性能与天然碎石相似,然而钢渣集料体积稳定性较差,遇水易发生膨胀,严重制约其在道路工程中的应用。本文首先综述了钢渣集料的物理力学性能和化学组成;分析了诱发钢渣集料体积膨胀的主要因素;介绍了当下抑制钢渣集料体积膨胀的改性方法并总结其优缺点;提出采用钢渣表面改性的方法可增强钢渣表面疏水能力,消除钢渣遇水发生反应的前提条件。由于不同地区钢渣化学成分差异明显,钢渣改性处理工艺相对复杂,应深入研究钢渣表面改性方法,同时兼顾低成本有机改性剂的制备及循环利用,真正实现“低成本,高利用”的目的。

    Abstract:

    The physical and mechanical properties of steel slag aggregate are similar to those of natural gravel, but the volume stability of steel slag aggregate is poor and it tends to expand when it meets water, which seriously restricts its application in road engineering. Firstly, the physical and mechanical properties and chemical composition of steel slag aggregate are reviewed. The main factors inducing volume expansion of steel slag aggregate are analyzed. The current modification methods for restraining volume expansion of steel slag aggregate are introduced and their advantages and disadvantages are summarized. The method of surface modification of steel slag can enhance the hydrophobic ability of steel slag surface and eliminate the precondition of steel slag reaction with water. Due to the obvious differences in the chemical composition of steel slag in different regions, the modification process of steel slag is relatively complex. Therefore, the surface modification method of steel slag should be further studied, and the preparation and recycling of low-cost organic modifier should be taken into account, so as to truly achieve the purpose of "low cost and high utilization".
