Variation of Strength Characteristics of Recycled Concrete due to Different Recycled Aggregate Contents

재생골재의 함량차이에 따른 재생콘크리트의 강도 특성

Various strength characteristics of recycled concretes containing different contents of recycled aggregates from waste concretes were compared with one another. Five different contents. 0%, 50%, 60%, 70% and 80%, of recycled concrete were used for this study. Study results showed that the compressive strength, flexural strength, tensile strength, elastic modulus and fracture toughness varied with contents of recycled aggregates. Target strength of the recycled concrete could be difined by nonparametric regression model as a funcion of content of recycled aggregate in the mix.
