Abstract
Urea can substantially reduce the temperature of concrete both at casting stage and during hydration process. However, not much is known about what effects urea can likely bring in concrete. In this study the influence of urea in concrete on flowability, heat of hydration, setting time, strength, shrinkage strain, and carbonation resistance are discussed. The results of the experiment show that apart from the fact that urea can reduce the hydration temperature in concrete, it can also enhance both flowability and durability of concrete.
