Copper slag, in amounts of 20, 40, 60, 80, and 100 percent, was substituted for fine aggregate in cement mortar and concrete. The fineness modulus of the combination of copper slag and fine aggregate was roughly 2.6, the optimum fineness modulus for concrete mix design. At this value, workability was found to be satisfactory with minimal bleeding.
Further, Copper Slag is also used in the production of cement, mortar, and concrete as a raw material for clinker, cement replacement, coarse and fine aggregates. Central Road Research Institute (CRRI) recommends usage of Copper Slag in road construction and structural fill applications. It is a very good substitute for soil for landfilling.

Cement, sand and aggregate are essential needs for any construction industry. . river sand or pit sand is used as fine aggregate in mortar and concrete. . by the Central Road Research Institute (CRRI) shown that copper slag may be used Optimum utilization of quarry dust as partial replacement of sand in concrete, Int.
Jan 16, 2017· Partial replacement of Fine aggreggate by Copper Slag and Cement by Fly Ash 1. 1 Replacement Of Fine Aggregate By Copper Slag And Cement By Fly Ash Ammini College Of Engineering, Mankara, Palakkad 1. INTRODUCTION 1.1 GENERAL Concrete is the man made material widely used for construction purposes.
The use of copper slag in cement and concrete provides potential environmental as well as economic benefits for all related industries, particularly in areas where a considerable amount of copper slag is produced. The addition of copper slag as fine aggregate .
Copper slag also has a high strength-to-weight ratio, making it an effective option in concrete, or as a fill material under the roadway. Some studies were carried out using grained copper slag as fine aggregate and fine powder copper slag for partial replacement of cement.
The effect of copper slag can be seen by replacing a part of the cement in concrete. The study conducted by CRRI, New Delhi showed that fine sand with copper slag upto 40% can be used as fine aggregate in pavement quality concrete as well as in dry lean concrete [4].
Use of copper slag in concrete industry as replacement of cement or/and fine aggregates can have the benefit of reducing the costs of disposal and minimising environmental pollution [1,2]. Little research work has been conducted to investigate the potential use of copper slag as fine aggregate on the properties of normal concrete. Akihiko and
Many researchers have investigated the use of copper slag in the production of cement, mortar and concrete as raw materials for clinker, cement replacement, coarse and fine aggregates. The use of ...
It was noticed that the use of copper slag as fine aggregate could greatly increase the abrasion resistance of the cement mortar (Tang et al., 2000). Hwang and Laiw (1989) evaluated the compressive strength development of mortars and concrete containing fine copper slag aggregate with different water to cement ratios (Fig. 4, Fig. 5).
Aug 20, 2014· Abstract. This work focuses on the use of copper slag, as a partial replacement of sand for use in cement concrete and building construction. Cement mortar mixtures prepared with fine aggregate made up of different proportions of copper slag and sand were tested for use as masonry mortars and plastering.
