Particle Packing Method for Recycled Aggregate Concrete

這本書強調商業上可用的從多個建築和拆除工地回收的再生骨料混凝土（RAC）的使用，將其視為傳統骨料的可行替代品。它進一步描述了先進的技術，例如掃描電子顯微鏡、納米壓痕、熱重分析和X射線微電腦斷層掃描，揭示了RAC的差劣宏觀力學性能的深層根本原因以及粒子填充法設計方法在這方面的優勢。然後，它通過宏觀力學性能研究、微觀結構表徵和斷裂分析描述了RAC的改善性能。對於結構混凝土的準備，系統而深入地介紹了再生粗骨料作為傳統骨料的替代品的使用，將引導研究人員進行後續的RAC研究，並為結構工程師和混凝土製造商在使用RAC方面提供幫助。
