Abstract:
The most common cause of cracking is restrained contraction. Principal causes of contraction are loss of moisture (drying shrinkage) and a decrease in temperature. Control of cracking by reducing drying shrinkage, change in temperature, and by modifying the properties of concrete is outlined.
