The shortage of natural construction aggregates, coupled with the large volumes of industrial solid wastes, is posing a significant challenge to sustainable development, thereby driving the advancement of artificial lightweight aggregates, particularly cold-bonded artificial aggregates (CBAA). On the one hand, CBAA receives increasing attentions in recent years due to its advantages in wastes recycling, low carbon emission, simple preparation process, and good performance. On the other hands, researches also indicated that the preparation and performance of CBAA varied greatly. In order to optimize the preparation process and attain a good quality of the CBAA, this article provides a state-of-the-art review on the preparation and performance of CBAA with influencing factors of raw materials, fabricating parameters and curing methods. In addition, this article also evaluates the physical properties, mechanical properties, functional properties, durability properties, and environmental attributes of CBAA, which helps confirm the feasibility and advantages on the application of CBAAs as traditional aggregates substitution in construction. This review helps to understand the application of CBAA in construction through front-end granulation analysis to post-performance evaluation, and lays the foundation for promoting the sustainable development of the construction industry.

关于从固体废物开发的冷粘人造骨料的批判性综述：从造粒分析到性能评估


天然建筑骨料的短缺，加上大量的工业固体废物，对可持续发展构成了重大挑战，从而推动了人造轻质骨料的发展，特别是冷粘人造骨料 （CBAA）。一方面，CBAA 因其在废物回收利用、碳排放低、制备工艺简单、性能好等优点，近年来受到越来越多的关注。另一方面，研究还表明 CBAA 的制备和性能差异很大。为了优化制备工艺，获得良好的CBAA质量，本文从原材料、制造参数和固化方法的影响因素出发，对CBAA的制备和性能进行了综述。此外，本文还对 CBAA 的物理性能、力学性能、功能性能、耐久性性能和环境属性进行了评价，有助于确认 CBAA 作为传统骨料替代品在建筑中的应用可行性和优势。本文通过前端造粒分析到后绩效评价，有助于理解CBAA在建筑中的应用，为推动建筑业的可持续发展奠定基础。
