PROPERTIES AND EFFECTS OF COPPER SLAG IN CONCRETE

from specific gravity and water absorption tests revealed that copper slag has a specific gravity of 3.30 which is higher than that of sand, whereas the water absorption values for copper slag and sand were about 0.65% and 1.01%, respectively. This suggests that concrete produced with large copper slag substitution would have larger density values than concrete produced with sand alone. On the ...
