內(nèi)容簡介:　　Steel Corrosion-Induced Concrete Cracking presents the results of the authors' research into the origins，mechanisms， and the development of steel corrosion-induced cracking in concrete. The book fills an important gap in the literature by providing comprehensive analysis of the concrete cracking process that is specificallycaused by steel corrosion.
　　Steel Corrosion-Induced Concrete Cracking enables industry engineers and researchers in the field of concretestructures and durability to improve the serviceability limit state of the structures they design by enablingthem： to identify the mechanisms of deterioration/steel corrosion; to more accurately calculate the lifecycle ofreinforced concrete; to mitigate cracking and spalling; and to identify and then avoid practices which lead toearly corrosion-induced cracking， and/or accelerate the propagation of cracks.
