Abstract
Waste concrete accounts for the largest portion of construction waste, and the supply of natural aggregate is unstable. Therefore, importance of using recycled aggregate is emphasized. The purpose of this study is to investigate the mechanical properties of high strength concrete according to the replacement rate of recycled coarse aggregate. For this purpose, the target design compressive strength was set to 40MPa, and the substitution rates of the recycled coarse aggregate were set to 0%, 30%, 60%, and 100%, respectively. Through experiments on the unreinforced concrete and hardened concrete, The validity of the use was confirmed. In addition, LCA method was used to evaluate the environmental impact of recycled aggregates and to compare and analyze the environmental impacts of the aggregates.
