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