Abstract
Effect of copper slag on the hydration of cement based materials is studied. Up to 15% by weight of copper slag was used as a portland cement replacement. Activation of pozzolanic reactions were studied using up to 1.5% hydrated lime. Hydration reactions were monitored using quantitative X-Ray diffraction (QXRD) and the porosity was examined using mercury intrusion porosimetry (MIP). Results indicate a significant increase in the compressive strength for up to 90 days of hydration. A decreases in capillary porosity measured using MIP indicated densification of the microstructure. The embrittlement due to the addition of slag is measured using fracture parameters. Fracture properties such as critical stress intensity factor, and fracture toughness, Gf showed a constant or decreasing trend with the addition slag.
