摘要

Demand for natural aggregate is increasing more and more in Korea, but existing amount of natural aggregate is decreasing. The amount of waste generated during disassembly of the building is increasing every year. Construction waste is generated environmental pollution to increasing. As a measure, the use of recycle aggregate for the circulation of construction waste. In addition, the studies on normal-strength concrete of using the recycle aggregate is many done, and but the study of high-strength concrete is insufficient. Therefore, this study was purpose to the analyzed change in the compressive strength in accordance with the replacement ratio by using a high-strength concrete recycle aggregate of 40, 50 and 60(MPa) design strength.
