재생골재 콘크리트의 건조수축 및 크리프에 관한 실험적 연구 = An Experimental Study on the Drying Shrinkage and Creep of Recycled Aggregate Concrete

다국어 초록 (Multilingual Abstract)

The purpose of this study which it sees follows the recycled aggregate in transfer ratio and the mechanical property of the recycled aggregate concrete which it does with the mixture aggregate, it evaluates the hold a drying shrinkage and the creep the effect, it analyzes quality and reliability of the recycled aggregate concrete there is.
The result of study are as follows. (1) The compressive strength of the recycled aggregate concrete which uses the recycled coarse aggregate followed in increase of recycled aggregate transfer ratio and the compressive strength increases with the fact that, 5.4% strength improvement result which average 29.2N/㎟ as the compressive strength of the normal concrete 27.7N/㎟ it sees whole at scope of 27.6-31.0N/㎟ appeared. (2) The compressive strength of the recycled aggregate concrete which uses the recycled fine aggregate by recycled aggregate transfer ratio 30% with the normal concrete is the level which is similar from all strength scope or it shows the strength which improves more or less, some it shows the tendency which decreases from transfer ratio above that and it is use. (3) The length change ratio from 12 weeks material ages of the recycled aggregate concrete uses the recycled coarse aggregate with the mixture aggregate due to a drying shrinkage from former blending appeared at 4.1~4.6×10^(-4) degree, transfer length change ratio of the normal concrete which it does not use 4.8×10^(-4), 18.5~3.9% where it sees it appeared small. (4) The scope of creep strain of the recycled aggregate concrete which transfers with the recycled coarse aggregate the tendency which is special it follows whole in 8.32~8.48×10^(-4) as transfer ratio was not visible not to be, creep strain of the normal concrete 7.70×10^(-4) the maximum 10.1% which it sees it appeared highly.
