R. Tixier et al., THE EFFECT OF COPPER SLAG ON THE HYDRATION AND MECHANICAL-PROPERTIES OF CEMENTITIOUS MIXTURES, Cement and concrete research, 27(10), 1997, pp. 1569-1580
The effect of copper slag on the hydration of cement-based materials i
s studied. Up to 15% by weight of copper slag was used as a portland c
ement replacement. Hydration reactions were studied through semiquanti
tative Xray diffraction and TGA/DTA. Samples of copper slag and hydrat
ed lime (ASTM type S) were used to test the pozzolanic properties of t
he 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. (C) 1997 Elsevier Science Ltd.
