Experimental Study of Flexural Behavior of Reinforced Concrete Beams with Different Types of Coarse Aggregates

순환골재 치환률에 따른 철근콘크리트 보의 휨거동에 관한 실험적 연구

This study is to evaluate flexural behavior of RC beam with different types of coarse aggregates, so called natural or recycled aggregate. Two reinforced concrete beams were manufactured with different replacement level of recycled coarse aggregates : Concrete made with 0% of coarse aggregates, concrete made with 100% of recycled coarse aggregates. From the test, the general flexural performances of RC beams with different types of coarse aggregates such as cracking moment, crack patterns, maximum moment/crack width are discussed.
