This research represents an experimental study on influence of urea on concrete through various tests on urea, cement, concrete and water. Test of finesses modulus, slump test, carbonation test, pH test, urea ingression test and increase in strength with urea percentage .This study deals to overcome three major problems in the concrete namely heat of hydration, permeability, and corrosion of steel bar embedded in concrete. Urea can generally reduce the temperature of concrete both at casting phase and during the procedure of hydration. Urea does not opposite effect the durability of reinforced concrete, except where there is an accumulation of urea crystal growth.
