Briefing: Concrete structures affected by cracking

摘要

Much of the world's critical infrastructure consists of concrete structures. Cracking is a feature of concrete that, although it does not usually constitute a serious problem, may have adverse impacts on durability, structural integrity, watertightness, sound transmission and aesthetics. This may in turn impact on the serviceability of concrete structures for various reasons. This briefing introduces the types of serviceability issues that involve concrete cracking and discusses a number of topical case studies.
