copper slag blended cement

Copper slag is a by-product generated during smelting to extract copper metal from the ore. The copper slag obtained may exhibit pozzolanic activity and may therefore be used in the manufacture of addition-containing cements. In this paper the effect of the incorporation of the copper slag in cement is measured.

As one of the by-products in the steel industry, granulated blast furnace slag (GBFS) is widely used as an aggregate or a pozzolanic material (a partial replacement for Portland cement) in the concrete mixture after the crushing or grinding process. However, using a basic oxygen furnace slag (BOFS) as a cementitious material is limited because of its inherent shortcomings such …

The use of copper slag in cement and concrete provides potential environmental as well as economic benefits for all related industries, particularly in areas where a considerable amount of copper slag is produced. This paper reviews the characteristics of copper slag and its effects on the engineering properties of cement, mortars and concrete.

compressive and tensile strength performance of copper slag and silica fume. Respective graphs and discussion will be made to find out the optimum result and make it more sustainable product to be used for the construction. Keywords-Copper slag, Silica Fume, Blended concrete, compressive strength, split tensile strength.

Cement is made from base metal smelter slag produced by a nickel, copper, lead or zinc smelter. The slag is ground to a size within the range of from about -250 to about 425 mesh to produce ground slag cement, and the ground slag cement is mixed with Type 3 high early strength Portland cement in a ratio of at least about 0.5:1 by weight to produce a blended …

The copper slag, the by product of the melting plant of Lac, north Albania can be used successfully as Portland cement substitute in the cement industry. Copper slag is one of the materials that is considered as a waste material which could have a promising future in construction industry as partial substitute of either cement or aggregates.

Blended cements including supplementary cementitious materials are substitute of Portland cement to reduce CO2 emission. The present paper investigates theappropriateness of copper slag (CS) as supplementary cementitious material. Strength properties and hydration of mixes were determined at different replacement levels of CS with cement.

Various percentages of copper slag were considered, including 0%, 20%, 40%, 60%, and 80%. Compressive strength rises as the amount of copper slag in the mix rises, and it's inversely proportional to water-cement ratios. The compressive strength of copper slag blended concrete reduces as the water-cement ratio rises [4].

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].
