The purpose of this research is to investigate characteristics of lathe scrap formanufacturing fiber reinforced cementitious composites(FRCCs) to use lathe scrap as aalternative materials of steel fiber. It should be noted that the use of the lathe scrap formaking FRCCs raised friendly environmental effect as well as economy because the lathescrap was a by-product of steel manufactures. For this purpose, various steel scraps werecollected from processing plants of metal and then their physical properties wereevaluated. Also, steel scraps were classified and analyzed according to the KS D 2101 andthen of these scraps, lathe scrap as a alternative materials of steel fiber was suggested. Inaddition, FRCCs containing lathe scraps were made according to their total volumefractions of 0.0, 0.5, 1.0, 1.5, and 2.0% for water-binder ratios of 30%, 40%, respectively, andthen characteristics, such as the workability, compressive strength, and flexural strength ofthose were evaluated. It was observed from the test result that the compressive strengthsat 7 and 28 days of FRCCs containing lathe scrap were slightly small but the flexuralstrengths at 28 days of those increased by 10% compared with plain concrete.

이 연구의 목적은 섬유보강 시멘트 복합체(Fiber Reinforced Cementitious Composites,FRCCs) 제조시 강섬유의 대체재료로서 선반 스크랩을 활용하기 위하여 그것의 특성을 규명하는 것이다. FRCCs 제조시 선반 스크랩을 활용함으로써 경제성 뿐만 아니라 친환경 효과를 도모할 수 있다. 이를 위하여 금속 가공공장으로부터 여러 종류의 강 스크랩을 수집한후 이들의 물성을 평가하였으며, KS D 2101에 따라 강 스크랩을 분류․분석하여 강섬유를대체할 수 있는 선반 스크랩을 제시하였다. 물-결합재비 30% 및 40%에 대해서 선반 스크랩혼입률(전체 체적의 0.0, 0.5, 1.0, 1.5, 2.0%)에 따라 FRCCs를 제조한 후 이들의 작업성, 압축강도 및 휨강도를 평가하였다. 그 결과, 선반 스크랩을 혼입한 FRCCs의 압축강도는 보통콘크리트보다 다소 작은 것으로 나타났으나, 휨강도는 보통 콘크리트보다 약 10% 정도 증가하는 것으로 나타나, FRCCs 제조시 선반 스크랩은 활용 가능성이 있는 것으로 나타났다.
