An Experimental Study on the Evaluation of Compressive Strength of Recycled Aggregate Concrete by the Core and the Non-Destructive Testing

코어 및 비파괴 시험에 의한 재생골재 콘크리트의 압축강도 평가에 대한 실험적 연구

Compressive strength of recycled aggregate concrete was tested by the core and by the non-destructive testing. A prediction model of compressive strength considering the replacement level of recycled aggregate was suggested by multi-regression analysis and was compared with test results. Also, Test results showed that the ratio of compressive strength by core and non-destructive testing to actual was somewhat affected by the replacement level of recycled aggregate.
