（1）稻壳灰中含有无定形SiO₂，这赋予了稻壳灰一定的火山灰活性，使其具备作为混凝土辅助胶凝材料的可行性。稻壳灰的火山灰活性与其制备方法有关，本文主要指煅烧和研磨两种方法，实际应用时，应根据稻壳的来源、类型、稻壳灰细度，同时考虑经济和环境效益，选择合适的煅烧方法及相关工艺参数。
（2）在混凝土中掺入适量稻壳灰能够有效提高混凝土的耐久性能和力学性能，但会降低混凝土的工作性，这主要与稻壳灰细度有关。实际应用时，应综合考虑混凝土的耐久性能、力学性能和工作性，确定合适的稻壳灰掺量和细度。
（3）目前，研究人员们关于不同细度稻壳灰替代水泥的最佳比例还未得出一致结论，后续还需通过大量试验研究确定不同细度稻壳灰的合适掺量范围，以供相关研究方向的研究人员们参考。
