Abstract: A series of direct shear tests was conducted at normal stress of 50,100, 200, 300 and 400 kPa in order to study the peak friction angle, dilation angle and critical state friction angle of the angular steel slag. The different relative densities at which tests were conducted are 20%, 50%, and 80% respectively, with corresponding unit weights are 17.75 kN/m3, 18.15 kN/m3and 18.57 kN/m3respectively. Most of the direct shear tests were conducted to shear strain in excess of 40% to achieve the critical state. All the tests are conducted at constant strain of 0.05 mm/min. The stress-strain response was observed and recorded, and the shear strength and dilatancy parameters were obtained for each relative density and normal stresses. Also in the present work, a correlation between peak friction angle, dilatancy angle and critical state friction angle was obtained for steel slag. It was observed that as the normal stress increases, both frictional angle and dilatancy angle was found to decrease. Also as noted increase in density increases friction and dilatancy angle. The present data were also compared with those of established correlations by Bolton (1986) and Kumar (2007) and found to compare well.
