Alkali-activated materials (AAMs) are considered to be alternative cementitious materials for civil infrastructures. Nowadays, efforts have been made in developing AAMs with self-compacting ability. The obtained self-compacting AAMs (SCAAMs) accomplish superior passing and filling properties as well as excellent mechanical and environmental advantages. This work critically revisits recent progresses in SCAAMs including mixture proportions, fresh properties, mechanical strength, microstructure, acid and sulfate resistance, high temperature behaviors, impact resistance and interface shear strength. To facilitate direct comparison and interpretation of data from different publications, mixture proportions were normalized in terms of the content of key reactive components from precursors and activators, and correlation with mechanical behaviors was made. Moreover, special attention was paid to current research challenges and perspectives to promote further investigation and field application of SCAAMs as advanced construction material.
碱激活材料（AAMs）被认为是土木工程中替代水泥基材料的一种选择。如今，人们致力于开发具有自密实能力的 AAMs。所得到的自密实 AAMs（SCAAMs）具有优异的通过和填充性能以及出色的机械和环境优势。这项工作批判性地回顾了 SCAAMs 的最新进展，包括配合比、新性能、机械强度、微观结构、耐酸和耐硫酸盐性、耐高温性能、抗冲击性和界面剪切强度。为了便于直接比较和解释来自不同出版物的数据，配合比是根据前体和活化剂中关键反应性成分的含量进行归一化的，并与机械性能进行了关联。此外，特别关注当前的研究挑战和前景，以促进 SCAAMs 作为先进建筑材料的进一步研究和现场应用。
