Effect of Non-Ground Copper Slag on Properties of Concrete

Copper slag is material that widely used in blasting to prepare the steel for painting
purposes. Major problem that arise regarding this materials are the way to dispose this
material. Thus, this research was carried out to study the potential of copper slag as
cement on properties of the concrete. Mortar specimen with non-ground copper ranging
from 0% to 30% of cement weight were tested to determine the compressive strength,
tensile strength, and permeability of the concrete. Results demonstrated that there is
general an increase in the density and workability of concretes as copper slag quantity
increases. Also results showed that the compressive strength of concrete is generally
improved, compared with the control mix, with the increase of copper slag up to a
certain copper slag content beyond which the strength generally reduces.
