Abstract

In this study, cogeneration power plants that use biomass as a raw material to convert them into energy have recently received a lot of attention worldwide and are gradually increasing in South Korea. Therefore, in order to confirm the possibility of using the generated floor material as a fine aggregate for concrete, properties and stability evaluation experiments were performed. Compared to standard sand, the compressive strength of wood chip aggregate was improved by 11 % to 111 %, the length change rate was 89 %, and the waste processing test results met all criteria for hazardous substances. All of these are satisfied, and it is judged that the floor materials by the cogeneration power plant can be used as a fine aggregate for concrete.

이 연구는 바이오매스를 원료로 사용하여 에너지화하는 열병합 발전소가 최근 전 세계적으로 많은 관심을 받고 있고 국내에서도 점차 증가하고 있는 추세에 있으며 이로 인하여 발생하고 있는 바닥재를 콘크리트용 잔골재로서 활용하기 위한 가능성을 확인하기 위하여 기초 물성 및 안정성 평가 실험을 수행하였다. 표준사 28일 기준 압축강도와 비교하여 목재칩 골재는 111 %, 표준사 56일 기준 길이변화율과 비교하여 목재칩 골재는 89 %, 폐기물공정시험 결과 폐기물관리법 시행규칙에 따른 유해물질의 기준 미만을 모두 충족하여, 열병합발전소로 인하여 발생하는 바닥재를 콘크리트용 잔골재로 활용할 수 있을 것으로 판단된다.
