Abstract

It should be noted that the use of the lathe scrap for making fiber reinforced cementitious composites raised friendly environmental effect as well as economy because the lathe scrap is a by-product of steel manefactures and is occurred when lathe and milling works of them are conducted to process steel manufactures. Thus, the purpose of this experimental research is to investigate workability and strength characteristics of lathe scrap reinforced cementitious composites(LSRCCs). For this purpose, three types of lathe scraps were collected from processing plants of metal, and then LSRCCs containing these were made for 2mm width and 40mm length. As a result, it was observed from the test results that the workability of LSRCCs was slightly decreased than plain mortar and the flexural strength of LSRCCs were much larger than these of plain mortar and effect of types of lathe scrap on the characteristics of LSRCCs were somewhat large.

선반 스크랩은 금속 가공 공정에서 선반 및 밀링 작업에 의해 발생된 철강제품의 부산물이므로, 섬유보강 시멘트 복합체 제작시 이를 활용할 경우 경제성뿐만 아니라 환경 친화적인 효과를 가져온다. 따라서 이 연구의 목적은 강섬유 대체재료로서 선반 스크랩의 활용 방안을 제시하기 위하여 선반 스크랩 보강 시멘트 복합체(LSRCCs)의 작업성 및 강도 특성을 평가하는 것이다. 이를 위하여 금속 가공공장에서 3종류의 선반 스크랩을 채취한 후 폭 2 mm, 길이 40 mm로 가공하여 LSRCCs를 제작하였다. 그 결과, LSRCCs의 작업성은 플레인 모르타르보다 약간 저하되었고, 휨강도는 크게 개선되었으며, 선반 스크랩의 종류가 LSRCCs의 특성에 다소 영향을 미치는 것으로 나타났다.
