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 …
Hydration and strength development in blended cement with ...
This study aims at evaluating the effect of ultrafine granulated copper slag (UGCS) on hydration development of blended cement and mechanical properties of mortars. The UGCS with the median particle size of 4.78 μm and BET surface area of 1.31 m2/g was used as a cement replacement to prepare blended cements.
Copper Slag Blended Cement: An Environmental Sustainable ...
Blended cements including supplementary cementitious materials are substitute of Portland cement to reduce CO 2 emission. The present stone 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.
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.

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.
Portland, Blended, and Other Hydraulic Cements
Portland, Blended, and Other Hydraulic Cements Blended Hydraulic Cement ASTM C 595 General — a hydraulic cement consisting of two or more inorganic constituents, which contribute to the strength gaining properties of cement.
Study of Strength Properties of Concrete by Partial ...
mechanical functions of concrete and the application of copper slag as a substitution replacement material of sand. Copper slag which is an industrial waste product can be used as replacement for cement with sand and contributes to the increase in various mechanical properties of concrete. Copper slag can be used up to 30% but when
Copper Slag - an overview | ScienceDirect Topics
The physico-mechanical characteristics of copper slag suggest that it can be utilized in the cement and concrete industry (Shi et al., 2008). Granulated copper slag exhibits pozzolanic properties, and then, it could be used as a constituent for common Portland cement.
Corrosion and Leaching Studies in Blended Copper Slag Mortar
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. The effect of copper slag on the hydration of cement-based
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.
Use of recycled copper slag for blended cements - CORE
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 compressive strength in a similar way to fly ash; however, after 28 days, …
Blended Cements - Barzin Mobasher
In the area of blended cements mour team has specialized in teh use of blended Class C, F, and N flyash, copper slag, Matakaolin, and Wollastonite. It is imperative that new research, guidelines, and laboratory evaluation of these supplementary cementitious systems be developed for proper utilization.
Effect of copper slag on the hydration of blended ...
Effect of copper slag on the hydration of cement based materials is studied. Up to 15% by weight of copper slag was used as a portland cement replacement. Activation of pozzolanic reactions were studied using up to 1.5% hydrated lime.
Use of recycled copper slag for blended cements, Journal ...
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.
