Abstract

When fiber reinforced concrete is manufactured, it is useful to utilize lathe scrap as an aiternative material of steel fiber, because it is not only economical as an by-product of steel manufactures, but also has a very similar composition to that of steel fiber. The purpose of this experimental research is to evaluate the compressive strength and tensile behavior and then propose a material model of lathe scrap reinforced mortar. For this purpose, the lathe scrap reinforced mortars were ma de a ccording to their tota l volume fra ction of 1.5 % for wa ter-binder ra tio of 30 % a nd 40 %, respectively, a nd then the mechanical properties such as compressive strength, direct tensile strength, and stress-strain curve of those were evaluated. Also, based on the experimental results of lathe scrap reinforced mortar the material model for tensile behavior was suggested. It was revealed that the experimental results and the proposed material model corresponded relatively well.

섬유보강 콘크리트 제조 시 감섬유 대체재료로서 선반 스크랩을 활용하는 것이 효과적이다. 왜냐하면, 선반 스크랩은 철강 제품의 부산물로서 경제적일 뿐만 아니라 강섬유의 조성과 매우 유사하기 때문이다. 본 연구의 목적은 선반 스크랩 보강 모르타르의 압축강도 및 인장거동을 평가한 후 인장거동에 대한 재료모델을 제안하는 것이다. 이를 위하여 물-결합재비 30 % 및 40 %에 각각에 대하여 선반 스크랩을 총 부피비의 1.5 %를 혼입한 선반 스크랩 보강 모르타르를 제작한 후 압축강도 및 인장거동 등의 역학적 특성을 평가하였다. 또한 선반 스크랩 보강 모르타르의 실험 결과를 바탕으로 인장거동에 대한 재료모델을 제안하였으며, 제안한 모델은 실험 결과와 비교적 잘 일치하는 것으로 나타났다.
