Natural resources depletion is gradually becoming a critical burden on the environmental and ecological balance, pushing the development of artificial aggregates forward. In order to curb the shortage issues of natural aggregates and minimize the destruction of land topography, alkali-activated aggregates (AAA) have gradually become a hot topic in recent years as a new application of alkali-activated materials (AAM) with the benefits of utilizing industrial by-products and waste materials. This article provides an overall review of the manufacturing process and engineering properties of two types of artificial aggregates, cold-bonded AAA (CB-AAA) and sintered AAA (ST-AAA). Their applications in concrete, besides the mechanical evaluation, durability performance, and leaching behavior, are summarized based on the existing research outcomes. Finally, the future perspectives and challenges of artificial aggregates development are also proposed.

自然资源枯竭逐渐成为环境和生态平衡的重要负担，推动了人工骨料的发展。为了遏制天然骨料的短缺问题，尽量减少对陆地地形的破坏，碱活化骨料（AAA）作为碱活化材料（AAM）的一种新应用，具有以下优点，近年来逐渐成为热门话题。利用工业副产品和废料。本文全面回顾了冷粘合 AAA (CB-AAA) 和烧结 AAA (ST-AAA) 这两种人工骨料的制造工艺和工程性能。在现有研究成果的基础上，总结了它们在混凝土中的应用，除了力学评价、耐久性能和浸出行为。最后，
