Leaching studies of copper from copper slag admixed concrete: 10x10x10cm 3 concrete cubes with water to cement ratio of 0.44 were cast using copper slag. After 24 hours, the mortar specimens were demoulded and kept immersed in various aqueous media such as tapwater, rainwater and sea water. Periodically copper leaching is estimated using AAS. The results of the study are shown in Table 13.
Hydration and strength development in blended cement with ...
copper slag in cement and concrete focus on the materials with fineness ranging from 0.3–0.7 m2/g [8,22,23], which is a big obstacle to its wide application. In the present study, ultrafine GCS (UGCS) was obtained by using vibratory milling. The hydration heat evolution of blended cement was detected by isothermal calorimetry. The effect of UGCS on the compressive strength development of ...
Hydration and strength development in blended …
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. Hydration heat emission of blended cement and mechanical performance …
Slag blended cement
Slag cement can be used to produce blended cement that complies with ASTM C595. The ASTM C595 type designation naming practice for binary and ternary blended cements containing slag cement identifies the blended cement constituent material content as illustrated in the following examples:
Optimization of copper slag waste content in blended ...
Optimization of copper slag waste content in blended cement production Some industrial wastes such as blast furnace slag, fly ash, silica fume, by-product gypsum and nonferrous metal slag can be used as raw material and blending components in the cement industry. The amount of any waste used in this way depends on many factors such as the stone and mineralogical composition of the waste ...

Copper Slag - an overview | ScienceDirect Topics
Copper Slag. CS has also been ground to determine its suitability for use as a component of cement (regardless of the type of cooling process applied), though information available in this area has often tended to be somewhat problematic (Lorenzo et al., 1991;
Utilization of copper slag in cement and concrete ...
Use of copper slag in blended cement. The use of copper slag as a pozzolanic material for a partial substitute for ordinary Portland cement and its effects on the hydration reactions and properties of mortar and concrete have been reported in several publications (Al-Jabri et al., 2006, Taha et al., 2007, Malhotra, 1993, Tixier et al., 1997, Ariño and Mobasher, 1999, Douglas and Mainwaring ...
Mechanical Activation of Granulated Copper Slag and Its ...
Keywords: mechanical activation; granulated copper slag; blended cement paste; pozzolanic activity; compressive strength; fineness 1. Introduction Copper slag (CS) is a by-product generated in the process of copper smelting and converting [1]. It has been estimated that for every ton of copper produced, there are about 2.2–3 tons of CS generated [2], resulting in an annual generation rate ...

Blended Cement - Characteristics, Types and Uses …
Blended cement can be defined as uniform mix of ordinary Portland cement (OPC) and blending materials such as silica fumes, fly ash, limestone and slag to enhance its properties for different uses. Blended cement can improve workability, strength, durability and stone resistance of concrete. In this article we discuss about characteristics, types, advantages and uses […]
Use of recycled copper slag for blended cements, …
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 stone the effect of the incorporation of the copper slag in cement is measured. Blends of copper slag with Portland cement generally possess properties ...

Effect of copper slag on the hydration of blended ...
AB - 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. Hydration reactions were monitored using quantitative X-Ray diffraction (QXRD) and the porosity was examined using mercury intrusion porosimetry (MIP ...
