Abstract |
When fiber reinforced concrete is manufactured, it is necessary to utilize lathe scrap as an alternative material of steel fiber, because it is a by-product of steel manufactures and is economical and has a very similar composition to that of steel fiber. The purpose of this experimental research is to investigate the direct tensile strength and flexural performance of lathe scrap reinforced cementitious composites (LSRCCs). For this purpose, lathe scrap (SCM440) was collected from a metal processing plant, and then after cutting it into 2 mm width and 40 mm length, LSRCCs with a lathe scrap volume fraction of 1.5 % were prepared. Also, the flexural performance such as the load-deflection curve, flexural strength, and flexural toughness as well as the direct tensile strength were evaluated for the manufactured LSRCCs. It was observed from the test results that the direct tensile strength and flexural strengths of LSRCCs were more or less increased than those of plain mortar, and also LSRCCs had flexural toughness that was not shown in the plain mortar.
