Small gradual increase in flexural strength at 28 days was observed with an increase in copper slag content. Drying shrinkage of PQC decreased with the increase in slag and the decrease in stone dust content. Abrasion resistance of concrete mixes containing slag was observed to be less as compared with that of non-slag concrete.

This paper reports on an experimental program to investigate the effect of using copper slag as a replacement of sand on the properties of high performance concrete (HPC). Eight concrete mixtures were prepared with different proportions of copper slag ranging from 0% (for the control mix) to . Concrete mixes were …

Abstract. Copper slag is a by-product obtained during the matte smelting and refining of copper. Singapore imports huge amount of copper slag to be used as abrasive material for ship clearing and repairing, and resulting in used copper slag as waste material. It has been estimated that 300,000 tonnes of copper slag needs to be disposed annually.

This paper provides the gist of the systematic review undertaken, involving evaluation, analysis, repackaging and modelling of all the literature that could be sourced on the subject. Copper slag (CS) and washed copper slag (WCS), as to be expected, have essentially similar basic physical (although WCS is usually finer than CS) and chemical …

Global copper slag (CS) emissions reached 57.2 million tons in 2021. Despite the increasing reuse of CS, the treatment of CS is still dominated by landfill so far, which not only occupies land resources but also causes damage to the environment. The application of CS to cement-based materials (CBMs) is one of the main approaches to …

Abstract – Copper slag is one of the materials which is considered as waste materials in the production of copper, which can be used as partial replacement of fine aggregates in concrete. This paper presents the results of an experimental study on various durability tests on concrete containing copper slag as partial replacement of sand.

Copper slag (CS) is a by-product of the copper smelting process and is one of the nonferrous metal residues. CS is mainly composed of Fe 2 O 3, SiO 2, and a …
