2008-1-28 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;

2017-12-3 4.1 Leaching of copper from copper slag admixed concrete Concrete cubes of size 10 × 10 × 10 cm were cast with water cement ratio 0.44 using copper slag. After 24 hours of casting the specimens were demoulded and kept immersed in tap water, rain water, and seawater. Periodically the copper leaching is estimated using AAS.

2007-5-1 The joint study aims to utilise the copper slag as raw mix component in the manufacture of Ordinary Portland Cement (OPC) and as a blending material for Portland Slag Cement (PSC). Hence while designing the raw mixes, every effort was made to keep the level of utilisation of copper slag to the maximum possible extent.

2017-12-3 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

2007-5-1 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.

2016-4-9 Copper slag is a by-product obtained from production of copper metal. As copper slag contains silica and alumina, it may exhibit pozzolanic property, and hence it may be re-use in ground improvement applications as a partial replacement of cement. Present study evaluates systematically the possible pozzolanic property of copper slag as well as studies the effect of copper slag on engineering ...

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. Blends of copper slag with Portland cement generally possess properties equivalent ...
