Copper Slag Blended Cement

Utilisation of copper slag for cement manufacture ...

Copper slag admixed mortar and concrete showed a lesser amount of leaching than solution due to the complex formation with cement mortar. Hence, copper slag can be used (2.5%) in raw mix for OPC and (35%) in manufacture of PSC. The material does not have any adverse impact on the performance of OPC and PSC.

Use of recycled copper slag for blended cements - de Rojas ...

Mar 01, 2008 · Blends of copper slag with Portland cement generally possess properties equivalent to Portland cement containing fly ash, but very different to the silica fume incorporation. Copper slag and fly ash reduce the heat of hydration more effectively than silica fume in mortars. The replacement of 30% cement by copper slag reduces the flexural and …

Blended Cements - Slag Cement Association

Slag cement can be used to produce blended cement that complies with ASTM C595, Standard Specification for Blended Hydraulic Cements2. Type I (SM), or slag-modified portland cement, contains less than 25 percent slag by mass of the finished cement. Type IS, portland blast-furnace slag cement, contains between 25 and 70 percent slag by mass of the finished cement.

Apr 26, 2019 · This study aims at evaluating the effect of ultrafine granulated copper slag (UGCS) on hydration development of blended cement and mechanical properties of mortars.

Blended Cements - Barzin Mobasher

The knowledge of using blended cement systems allows cost-effective solutions and a greater flexibility in meeting the design requirements. In the area of blended cements mour team has specialized in teh use of blended Class C, F, and N flyash, copper slag…

Utilization of copper slag in cement and concrete ...

Since the main composition of copper slag is vitreous FeSiO 3, it has low melting point and could reduce the calcination temperature for cement clinker. Thus, the use of copper slag to replace iron powder as iron adjusting materials facilitates cement production, reduces or eliminates the need of mineralizer.

Nonferrous Slags - Material Description - User Guidelines ...

Copper and nickel slags have been used as granular base and embankment materials, aggregate substitutes in hot mix asphalt, mine backfill materials, railway ballast materials, grit blast abrasives, roofing granule material, and in the manufacture of blended cements (granulated copper and nickel slags).

Portland, Blended, and Other Hydraulic Cements

Portland, Blended, and Other Hydraulic Cements. Portland Cement. By definition — a hydraulic cement produced by pulverizing clinker consisting essentially of hydraulic calcium silicates, usually containing one or more of the forms of calcium sulfate as an interground addition.

An Experimental Investigation on the Strength Parameters ...

of GGBS and copper slag and these both are blended in concrete to produce a double blended green concrete which will be an economically friendly concrete for which

Mechanical Activation of Granulated Copper Slag and Its ...

Mechanical Activation of Granulated Copper Slag and Its Influence on Hydration Heat and Compressive Strength of Blended Cement Yan Feng 1,2, Jakob Kero 2, Qixing Yang 3, Qiusong Chen 1,*, Fredrik Engström 2, Caisa Samuelsson 2 and Chongchong Qi 1 1 School of Resource and Safety Engineering, Central South University, Changsha 410083, China;

Optimization of copper slag waste content in blended ...

A copper slag (waste of Lac, Albania Copper Plant) and Portland cement (produced in Fushe- Kruja,Albania Cement Factory) are used as specific constituents in the binary mixes of blended cement experimented in this work.

Concrete Technology

Copper slag is a by-product of metallurgical industry. In this study up to 20 percent (by weight) of Portland cement is replaced by copper slag, and the suitable proportion of this material, based on compressive strength, is determined.

Slag - Wikipedia

Ferrous and non-ferrous smelting processes produce different slags. The smelting of copper, lead and bauxite in non-ferrous smelting, for instance, is designed to remove the iron and silica that often occurs with those ores, and separates them as iron-silicate-based slags. Slag from steel mills in ferrous smelting,...
