Title: The effect of copper slag on the hydration and mechanical properties of cementitious mixtures

Abstract

The 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. Hydration reactions were studied through semiquantitative X-ray diffraction and TGA/DTA. Samples of copper slag and hydrated lime (ASTM type S) were used to test the pozzolanic properties of the slag. The porosity was examined using mercury intrusion porosimetry. A decrease in capillary porosity was observed while the gel porosity was increased. A significant increase in the compressive strength for up to 1 year is observed.
