The effects of using copper slag as a replacement for sand on the physical properties of concrete were investigated Copper slag was classified into three types depending on particle size distribution Concrete mixes were prepared with different proportions of copper slag replacing the sand content, ranging from 0 ,...
The effect of ground copper slag GCS on the strength and fracture of cement-based materials is studied Up to 15 by mass of ground copper slag was used as a portland cement replacement The strength and fracture toughness of concrete samples were studied using closed-loop controlled compression and three-point bending fracture tests...
The effect of ground copper slag GCS on the strength and fracture of cement-based materials is studied Up to 15 percent by mass of ground copper slag was used as a portland cement replacement The strength and fracture toughness of concrete samples were studied using closed-loop controlled compression and three-point bending fracture tests...
In this paper, the effects of using copper slag wastes on hydration, gelling properties, mechanical properties, pozzolanic activity and durability aspects of concrete are studied It has been found that copper slag have micro pozzolanic effect in the study...
The slump of the concrete incorporating the copper slag as fine aggregate increased as more natural sand was replaced by copper slag Maximum slump obtained was 40mm which occurred at the 100 copper slag replacement as compared to slump of concrete mix...
The effect of copper slag substitution as a fine aggregate on the strength of concrete is given in Table 5, which presents the average 7- and 28 day cube compressive strength, the average 28 day tensile strength and the average 28 day flexural strength of concrete...
The effect of copper slag is investigated by replacing fine aggregate in concrete in the proportions of 10 , 20 , 30 , 40 , 50 60 and 100 The results obtained are analyzed and presented Keywords- Copper Slag, Compressive strength, Fine aggregate replacement, Polypropylene Fibers I...
Abstract Copper slag is a by-product obtained during matte smelting and refining of copper This work reports an This work reports an experimental procedure to investigate the effect of using CS as partial replacement of sand...
2 175 increase in the compressive strength was observed for geopolymer concrete with 40 copper slag as replacement for fine aggregate due to high toughness of copper slag Fig 2 Compressive Strength Results 42 One of the indirect tension test methods for concrete is split tension test...
Since the main composition of copper slag is vitreous FeSiO 3, it has low melting point and could reduce the calcination temperature for cement clinker Thus, the use of copper slag to replace iron powder as iron adjusting materials facilitates cement production, reduces or eliminates the need of mineralizer...
