An experiment was conducted to investigate the strength and durability properties of concrete having copper slag as a partial replacement of sand (fine aggregate) and results have been presented in this paper. chemical properties such as specific gravity of copper slag is 2.73, firmness modulus is about 8.01, crushing value is 26.37 %, impact value is 30.75% and water absorption is 30.75%. Thus, high magnetite production in the Peirce Smith converters is not desirable. The geotechnical properties include sieve analysis, specific gravity, maximum and minimum dry unit weights, angle of shearing resistance, one-dimensional compressibility, and permeability.

Copper slag and fly ash reduce the heat of hydration more effectively than silica fume in mortars. As its disposal becomes a concern for environmental protection agencies and governments, possible alternative outlets for this waste material are needed. the properties of slag can be tailored to the requirements of the targeted application. Non-magnetic. The slag, produced at the Amer¡can Smelt¡ng and Refining Company (ASAROOI plant in El Paso, Texas, is a by-product of refining copper ore in oil-fi¡ed reverberatory fur. The geotechn¡cal properties include sieve analys¡s, spec¡f¡c grav¡ty, They do not shatter when they are dropped or become brittle when cooled below 0°C. %PDF-1.6 %���� PDF Abstract.

Also, the measured water absorption for copper slag was 0.40 % compared with 0.83 % for sand. Therefore, the objective of this work is to understand the mechanism of magnetite formation during the blowing to slag and its dispersion in the slag in order to obtain the magnetite content in the range of 18% to 20% in the converter slag. Beyond which more voids and capillary channels appear in the microstructure of the concrete [9] , [10] . It is second only to silver as an electrical conductor. When copper liquid settles down in the smelter due to its higher density, the smears of copper slag remaining on the surface (also in liquid … Copper slag recommended less than 40% gives high mechanical properties. It has high friction angle due to a sharp angular shape. The color of copper slag is like a black glassy particle with granular material … Copper slag is a by-product obtained during matte smelting and refining of copper. Also, copper slag exhibits pozzolanic properties since it contains a low content of CaO, and it can possesses cementitious properties as CaO content increases or under activation of NaOH. Copper slag is an industrial by-product material or waste produced during the process of copper smelting and refining of copper. Copper slag is a voluminous waste material obtained during the manufacturing of copper (matte smelting process).
