✦ Synopsis

Recent fluorescent microscopic investigations of concrete structures have revealed that cracking can occur inside the bulk of concrete structures with or without any visible sign on the outer surfaces. It is also indicated that under certain conditions cracks can form shortly after or even before the outer form-works are removed. The relevant literature has been critically surveyed to identify the probable mechanisms of crack formation at early ages of concrete structures. In this survey the obvious mechanisms such as late hydration of CaO or early alkali-silica reaction have not beeq considered.
