This paper reports the effect of concrete using copper slag as fine aggregate replacement. In this project work, the concrete grade M40 was selected and IS method was used for mix design. The properties of material for cement, fine aggregate, coarse aggregate and copper slag were studied for mix design. The various strength of concrete like compressive, flexural and split tensile were studied ...

Many researchers have already found it possible to use copper slag as a concrete aggregate, because copper slag has similar particle size characteristics likely to that of sand. Fine grained powder of copper slag can be used as a supplementary cementing material to concrete and in cement clinker production.

Aug 20, 2014· 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. Three masonry wall panels of dimensions 1 × 1 m were plastered.

Copper slags have been used as aggregate substitutes in hot mix paving. Air-cooled slags can be used as coarse or fine aggregate, while granulated slags can be used as fine aggregate (Miller and Collins, 1976). Use of copper slag (15% mass) as a Portland cement replacement was reported by Arino-Moreno and Mobasher (1999). It affects the ...

Use of copper slag (CS) as a replacement for fine aggregate (FA) in RC slender columns was experimentally investigated in this study. Twenty columns measuring 150 mm x150 mm x 2500 mm were tested for monotonic axial compression load until failure. The concrete mixture included ordinary Portland cement (OPC) cement, fine aggregate, 10 mm coarse aggregate, and CS. The cpercentage of cement ...

The physical and chemical properties of copper slag were investigated. 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.
Get PriceIt 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).
