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 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. |
