페로니켈슬래그 미분말 및 혼화재의 복합사용이 VR 하수관 강도발현에 미치는 영향분석 = Analysis of the influence of combined use of ferronickel slag fine powder and admixture on VR sewage pipe strength development

국문 초록 (Abstract)

본 논문에서는 페로니켈슬래그 미분말 및 혼화재의 복합사용이 VR 하수관 강도발현에 미치는 영향분석에 관한연구를 실시하였다. 치환율을 변수로 시험을 실시하였으며, 휨강도 및 압축강도의 결과분석과 SEM 분석을 통한 강도발현 성능연구를 실시하였다. 휨강도 및 압축강도, SEM을 통한 미시적 분석을 통해, 각 경우 별 상관관계를 도출 할 수 있었다. 치환율은 OPC 질량대비 20%, 30%를 구분하여 페로니켈 슬래그 미분말 및 혼화재를 일정 비율로 치환하여 실시하였다. 치환율 20%일 경우 강도발현성능이 우수한 것으로 나타났으며, 휨 강도와 압축강도는 페로니켈 슬래그 미분말, 생석회, 석고, 염화칼슘을 혼화재로 복합사용 하였을 때 강도발현 성능이 가장 우수하였으며, 조밀한 미세구조 형태를 나타냈고, 재령 28일 이후에도 점진적 강도발현가능성이 보인다.

In this paper, the effects of ferronickel slag powder and admixture on the strength of VR sewer pipe were analyzed. the substitution rate was tested as a variable, and the strength development was studied through the flexural strength, compressive strength and using SEM microscopic analysis. bending strength, compressive strength results and micro analysis using SEM showed the correlation in each case. the substitution rates were 20% and 30% relative to the mass of the OPC respectively, and were substituted according to a constant ratio of ferronickel slag fine powder and mixture. when the substitution ratio was 20%, the strength development was excellent. also, bending strength and compressive strength were the best when the ferronickel slag fine powder, quicklime, gypsum and calcium chloride were used as the admixture, dense microstructural patterns appeared. the possibility of progressive strength development is shown after 28 days.
