A Study on the Properties of Recycled Aggregate Concrete applied to Mock-up

Mock-up에 적용한 재생골재콘크리트의 특성 연구

In this study, Mock-up was manufactured using recycled aggregate concrete and then analyzed with respect to physical properties. Finally, the applicability of recycled aggregates as constructional aggregates was reviewed by practically putting recycled aggregates concrete into construction. Right after mixing, the slump of recycled-aggregates concrete showed decreased slump as time goes by because the surface mortar of recycled aggregates absorbed the mix water with time passing. The air contents of recycled-aggregates concrete overall increase a little due to the effect of surface mortar of the aggregates. For strengths, the strengths of recycled aggregate concrete tended to decrease from the proportion of 30$\%$ to 100$\%$.
