The purpose of this study is to investigate the effect of the length of the chemical fibers (CF) on the mechanical properties of slag mixed with CF. Furthermore, the effect of the difference between fibrous wood chips (FWC) and CF on mechanical properties is to be examined. In this study, a series of consolidated drained triaxial compression tests were conducted on a material mixed with steelmaking slag and FWC assuming under sieve residue or CF. The chemical fiber length and curing periods were changed in this study. As a result, it was found that 2% by volume of the CF mixture increased both the shear strength and the residual strength compared to the slag. However, their increases were up to the fiber length of 20 mm. When 5% by volume of FWC, the length of which was about 18.9 mm, were mixed to the slag, there were no increases observed in both the shear strength and the residual strength.
