（1）电炉钢渣的化学成分与天然骨料相似，主要为含Ca、Si、Fe的氧化物，3种氧化物的总占比在70%以上，其中，较高含量的含Fe氧化物使得电炉钢渣的密度比天然骨料高10%~40%。
（2）电炉钢渣用作混凝土骨料时，其安定性和重金属浸出风险不容忽视。对于安定性，可采用陈化处理、高温改质处理、碳化处理等方式来改善；对于重金属浸出风险，可掺入适量稳定剂（SiO2、Al2O3等）来控制电炉钢渣的碱度，或在电炉冶炼末期向炉内喷入适量Si、Fe元素，还原电炉钢渣中的Fe、Ni、Cr重金属元素，从而降低重金属元素的浸出风险，保证电炉钢渣在混凝土中应用的安全性。
（3）掺入电炉钢渣会降低混凝土的工作性，这与电炉钢渣的多孔结构、粒径、形状等自身性能有关。实际应用时，需通过合理控制电炉钢渣的掺量和颗粒级配、适当增加用水量、掺入适量减水剂等方法来改善掺电炉钢渣混凝土的工作性。
（4）掺入电炉钢渣能够对混凝土ITZ的结构和性能起到一定的改善作用，这主要与电炉钢渣粗糙的表面结构和一定的参与水化反应能力有关。
（5）目前，关于大掺量（≥50%）电炉钢渣对混凝土力学性能的影响规律未达成共识，仍需进行深入研究。而关于低掺量（＜50%）电炉钢渣对混凝土力学性能的影响规律基本一致，即掺入适量电炉钢渣能够提高混凝土的力学性能。
（6）掺入电炉钢渣能够有效提高混凝土的抗碳化、抗渗、抗氯离子侵蚀、抗冻、抗硫酸盐侵蚀等耐久性能。
（7）电炉钢渣主要应用在道路工程中，结构工程应谨慎使用。此外，由于电炉钢渣具有高密度特性，后续可深入研究其在防辐射混凝土工程中的应用效果。
（8）我国针对电炉钢渣用作混凝土骨料的研究与应用缺乏系统的标准规范指导，后续可通过大量试验，建立相关标准规范，助力“双碳”目标早日实现。
（9）电炉钢渣的膨胀期较长，深入研究其膨胀性能有利于进一步推广电炉钢渣作为骨料在混凝土中的应用。后续需要探寻合适的测试方法来确定电炉钢渣在混凝土中发生膨胀的具体位置、持续时间，以便从抑制膨胀的角度出发，采用预处理电炉钢渣、调整混凝土配合比等方式来缓解掺电炉钢渣混凝土的膨胀问题。
