This book serves as an indispensable guide for engineers, scientists and researchers, exploring the fundamental aspects of corrosion in reinforced concrete. Its originality lies in the coupling between the reinforcement corrosion of reinforced concrete and its mechanical behavior.The authors describe the specific theoretical foundations of the corrosion of steel in concrete and its interactions with the structural aspects, including service cracking and defects in the placement of concrete.
The book contains a study of the mechanisms of degradation of the mechanical behavior of reinforcements and the reinforced concrete composite, such as reduction of ductility, bearing capacity, redistribution of efforts by formation of plastic hinges and increase in the beam deflection in service. A diagnostic method based on corrosion-induced crack detection is presented in the book, and then paired with a recalculation method which allows us to predict the different aspects of the residual mechanical behavior. Several end-of-life ELS and ELU criteria are described, and the authors propose an approach to estimate the residual lifetime. Finally, the book presents the cathodic protection that allows the progression of corrosion to be contained within the corroded structures.
As well as academics, this book is aimed at civil engineers who are faced with the issue of corrosion in aging structures.

商品描述(中文翻譯)
這本書是工程師、科學家和研究人員不可或缺的指南,探討鋼筋混凝土中腐蝕的基本方面。其獨特之處在於鋼筋混凝土的鋼筋腐蝕與其機械行為之間的耦合。作者描述了鋼在混凝土中腐蝕的具體理論基礎及其與結構方面的相互作用,包括服務性裂縫和混凝土施工缺陷。
本書包含對鋼筋及鋼筋混凝土複合材料機械行為退化機制的研究,例如延展性降低、承載能力減少、因塑性鉸形成而導致的應力重新分配,以及在使用過程中梁的挠度增加。本書提出了一種基於腐蝕引起的裂縫檢測的診斷方法,並與一種重新計算方法相結合,該方法使我們能夠預測殘餘機械行為的不同方面。書中描述了幾個使用壽命結束的極限狀態(ELS)和極限狀態(ELU)標準,作者提出了一種估算殘餘壽命的方法。最後,本書介紹了陰極保護技術,該技術可以控制腐蝕在受腐蝕結構中的進展。
除了學術界,本書還針對面臨老化結構腐蝕問題的土木工程師。
