Abstract

This experimental study investigates the replacement of conventional Portland cement and sand with non-sintered cement and ferro-nickel slag to formulate eco-friendly cement mortar. The examination aimed to understand the strength properties of non-sintered cement mortar using ferro-nickel slag as fine aggregate by classifying mortar production types, fine aggregates, and curing methodologies. From flexural and compressive strength tests, it was observed that non-sintered cement mortars, incorporating ferro-nickel slag as fine aggregate, exhibited superior strength when compared to both plain mortar and steam-cured non-sintered mortar. This increased strength is attributed to the influence of the particle size, density, and absorption capabilities of the ferro-nickel slag. Furthermore, X-ray Diffraction(XRD) analyses of the mortars verified the presence of MgO, a component of ferro-nickel slag, in the form of a composite oxide. This finding substantiates the consistent strength manifestation of non-sintered cement mortars utilizing ferro-nickel slag as a fine aggregate.

본 실험에서는 포틀랜드 시멘트와 모래를 비소성 시멘트와 페로니켈슬래그로 대체 사용하여 친환경 시멘트 모르타르를 제작하였다. 페로니켈슬래그가 적용된 비소성 시멘트 모르타르의 강도 특성을 파악하기 위해 골재 종류와 양생방법을 구분하였다. 휨 및 압축강도 시험 결과, 페로니켈슬래그가 적용된 비소성 시멘트 모르타르의 강도는 Plain과 증기양생을 실시한 비소성 시멘트 모르타르의 강도보다 높았다. 이는 페로니켈슬래그의 입도, 밀도 및 흡수율 특성에 따른 강도 향상 효과로 판단된다. 모르타르의 XRD 분석 결과, 페로니켈슬래그에 포함된 MgO 성분이 복합 산화물 형태로 존재하며, 이를 통해 페로니켈슬래그가 적용된 비소성 시멘트 모르타르의 안정적인 강도 발현을 확인하였다.
