copper slag in concrete production. Copper slag is one of the by-product materials from the copper smelting. In Indonesia, around 400,000 tons of copper slag are produced per year by Freeport Company and Newmont Company [3]. This number is a motivation for the researchers to study the copper slag as aggregate or cement replacement in concrete.

copper slag exhibits pozzolanic properties as CaO content in copper slag increases, it can exhibit cementitious properties. Studies [8-12] indicated that a copper slag, which contains approximately 19% CaO, show a good cementitious property under the activation of NaOH.

Mechanical activation of granulated copper slag (GCS) is carried out in the present study for the purposes of enhancing pozzolanic activity for the GCS. A vibration mill mills the GCS for 1, 2, and 3 h to produce samples with specific surface area of 0.67, 1.03 and 1.37 m2/g, respectively. The samples are used to replace 30% cement (PC) to get 3 PC-GCS binders.

Prior to the preparation of the blends with cement, the steel slag (size fraction: 0–5 mm) was ground, in a 1 kg laboratory ball mill using steel balls as grinding medium, to a specific surface area of about 3000 cm2/g (according to the Blaine air permeability method) [15]. Then, the blended cements were produced by mixing the slag and the ...
