In this study, the amount of construction waste created from Demolition and reconstruction of old buildings by environmental contamination by construction waste has been raised as a social problem, according as a means to settle problems the government is being encouraged the use Recycled aggregate. However recycled aggregate has not yet been applied to structures in many cases. Due to uncertain technical verification of long-term durability, the use of recycled aggregate is being limited. Accordingly in this study, High Strength Concrete Beams use Recycled coarse Aggregate to evaluate the performance of the bending and establish national standards for structural design of recycled aggregates aims to provide the basic data.
