Reduction of Autogenous Shrinkage of High-strength Concrete Based on Moisture Supply of Recycled Coarse Aggregate

순환 굵은골재의 수분공급에 의한 고강도 콘크리트의 자기수축 저감

This study aims to achieve an enhancement in the quality of high strength concrete through a reduction in autogenous shrinkage by supplying the moisture needed for hydration through recycled aggregates that retain high amounts of moisture. The result showed that, moisture supply increased with the higher replacement rate, autogenous shrinkage dropped by up to 45 percent.
