The combination of concrete and reinforcement in collaboration with the load is determined by the perfect bond of the two materials. The axial load is given in reinforced concrete results in internal cracking of reinforced concrete around the threaded reinforcement area. An area within the radius of cracking of the concrete around the reinforcement has also been obtained. The action is needed to reduce the area of cracked concrete by giving restraints using spherical spiral reinforcements within the concrete crack radius. It is expected to increase the strength of the reinforcement and concrete around it. The methodology used is Pull Out on single reinforced concrete cylindrical specimens with confinement and without confinement. Concrete cylindrical test specimens with a diameter of 150 mm 200 mm high with single reinforcement with a diameter of 10 mm, and spiral reinforcement as confinement with an identification diameter of 4 mm. Placed within the radius of cracking of the concrete around the reinforcement. The Pull Out test results indicate a cesarean movement from the edge that is loaded to the free end. The restrained specimen produces a larger cesarean at the end of the load, when the initial cesarean occurs at the free end.
