Abstract

In this paper, as part of a study for carbon neutrality, the quality properties of quaternary component high-fluidity concrete, which significantly replaced up to 80 % of the cement usage by using three industrial by-products, were evaluated. As a result of the evaluation, even if a large amount of industrial by-products were replaced by more than 80 % of the amount of cement used, it was possible to obtain quality that satisfies the target performance in all concrete mix. In the case of flow properties, mechanical properties, and durability, compared to the existing standard concrete mix, the performance tends to decrease, but it is judged that the performance above the required performance level can be satisfied. When considered comprehensively, the quaternary component High-Fluidity Concrete with a large mixing amount of fine powder of blast furnace slag showed relatively good performance.

본 논문에서는 탄소중립을 위한 일환의 연구로써 3가지의 산업부산물을 활용하여 시멘트 사용량에 대하여 80 %까지 대폭 대체한 4성분계 고유동 콘크리트의 품질특성을 평가하였다. 평가결과, 다량의 산업부산물을 혼합하여 시멘트 사용량을 80% 이상 감소시킨 배합에서 목표 성능을 만족하는 품질을 얻을 수 있었으며, 유동특성, 역학특성 및 내구특성의 경우 기존 기준 배합과 비교하여 다소 성능이 감소되는 경향이 나타났지만 소요성능 수준 이상의 성능을 만족할 수 있는 것으로 판단된다. 종합적으로 고려할 경우 고로슬래그 미분말 혼합량이 큰 4성분계 고유동 콘크리트가 상대적으로 우수한 성능을 보였다.
