In Sweden (Skellefteå region) fumed and settled granulated copper slag from the Boliden copper smelter is used as road-construction material. Copper is non-magnetic and non-sparking. � The specific gravity of copper slag is varying between 1.7-1.90 g/cc. Effect of Copper Slag As A Fine Aggregate on Properties . It is also having same properties of sand and it can be used as one of the alternative material in concrete. Fig -1: Copper Slag 1.3 BASIC PROPERTIES OF COPPER SLAG The slag is a black glassy and granular in nature and has a similar particle size range like sand which indicate that it could be tried as replacement for the sand in cementite’s slag mixture. Copper slag and fly ash reduce the heat of hydration more effectively than silica fume in mortars. Slag properties are important since they: (i) have a decisive effect on both process control and on the quality of the product and E. S – 2 (ii) good quality property data are needed to develop reliable mathematical models of the process and to optimise the efficiency of the process and quality control. They do not shatter when they are dropped or become brittle when cooled below 0°C. Properties: Copper has a melting point of 1083.4 +/- 0.2°C, boiling point of 2567°C, specific gravity of 8.96 (20°C), with a valence of 1 or 2. Attractive Colour . Enter the email address you signed up with and we'll email you a reset link. The slag properties, particularly slag viscosity and electric conductivity, play very important roles in copper concentrate smelting in the Teniente Converter and in slag cleaning in the electric furnace. Processed air-cooled and granulated copper slag has a number of favourable mechanical properties for aggregate use, including excellent soundness characteristics and good abrasion resistance.
