dc.description.abstract | 이 연구의 목적은 인공경량골재 콘크리트의 생산에서 CO2 배출량을 저감시킬 수 있는 천연모래 치환 기반의 배합설계 절차를 제시하는 것이다. 379개의 경량골재 콘크리트 배합 데이터를 사용하여 CO2 배출량과 콘크리트의 압축강도에 대한 천연모래의 치환율의 영향을 평가하였다. Yang et al.이 제시한 배합설계절차 및 데이터베이스를 이용한 비선형 회귀 분석에 기반하여 목표 성능(압축강도, 초기 슬럼프, 공기량 및 CO2 저감률)을 만족하기 위한 천연모래의 치환율 및 콘크리트 배합설계를 결정할 수 있는 간단한 모델식을 제시하였다. 뿐만 아니라, 제안된 모델식은 주어진 경량골재 콘크리트 배합표에서 CO2 배출량을 직접 계산하는데 효율적으로 이용될 수 있다. | - |
dc.description.abstract | The purpose of this study is to propose a mixture proportioning approach based on the replacement level of natural sand for reducing CO₂ emissions from artificial lightweight aggregate concrete(LWAC) production. To assess the effect of natural sand on the reduction of CO₂ emissions and compressive strength of LWAC, a total of 379 specimens compiled from different sources were analyzed. Based on the non-linear regression analysis using the database and the previous mixture proportioning method proposed by Yang et al., simple equations were derived to determine the concrete mixture proportioning and the replacement level of natural sand for achieving the targeted performances(compressive strength, initial slump, air content, and CO₂ reduction ratio) of concrete. Furthermore, the proposed equations are practically applicable to straightforward determination of the CO₂ emissions from the provided mixture proportions of LWAC. | - |
