Abstract

Urea is liquefied when it is dissolved in water and has the effect of increasing water. It is known that when using urea, it is generally possible to reduce the number of design units in order to ensure the same flow-ability, because the effect of increasing the water when using urea in the manufacturing of concrete is known. In this study, the change of basic properties of concrete when using urea was investigated in concrete production, and the effect of reducing the unit yield was confirmed.
