Obtaining accurate strength of structures in estimating safety to the established concrete structures is very important task. However, To obtain real strength with reliability, strength test or loading test based on core extraction ought to accept not only damage to the structure but also cost and time. Recently, a variety of methods that are able to estimate strength to structures without damage are studying according to developing technology, and method using Rebound Hammer Test is broadly used because of convenience and reliability of estimation. Therefore, strength estimation method to structures considering magnitude and importance of facilities and correcting strength estimation value through nondestructive test used widely.
