Abstract

The effect of ground copper slag (GCS) on the strength and fracture of cement-based materials is studied. Up to 15 percent by mass of GCS was used as a portland cement replacement. The strength and fracture toughness of concrete samples were studied using closed-loop controlled compression and three-point bending fracture tests. The compression test used a combination of the axial and transverse strains as a control parameter to develop a stable postpeak response. A cyclic loading-unloading test was conducted on three-point bending notched specimens under closed-loop crack mouth opening control. Test results were used to construct the resistance curve (R-curve) response of the specimens describing the dependence of fracture toughness on the stable crack length.
