with copper slag as a fine aggregate at constant workability and studied the effect of super plasticizer addition on the properties of HSC made with copper slag. There was a decrease in the surface water absorption as copper slag quantity increased up to 40% replacement. Beyond that level of replacement, the absorption rate increases rapidly. 2.
Copper smelting slag (CSS) are waste slag obtained from smelters after reusing sulphur smelting slag. This study explores the potential of CSS to serve as a resource in cement mortar construction. Specifically, the study investigates the use of mechanical and chemical methods to enhance the volcanic ash activity of CSS, enabling them to replace up to 30 …
In the last few decades, the concrete industry has been massively expanded with the adoption of various kinds of binding materials. As a substitute to cement and in an effort to relieve ecofriendly difficulties linked with cement creation, the utilization of industrial waste as cementitious material can sharply reduce the amount of trash …
The use of copper slag in the concrete industry as a partial replacement for cement and/or fine aggregates could potentially reduce environmental harm and also reduce the costs of slag disposal ...
Table 1 shows the results of oxide analyses for Portland cement, copper slag, and silica sand, which were conducted using X-ray fluorescence (XRF). The specific gravity of Portland cement was measured by following the ASTM C 188 (ASTM, 2009); the specific gravities, water absorptions, and fineness moduli of aggregates were obtained …
The iron-making and steel-making industries produce four types of slags, named after the processes from which they are produced (Fig. 2): Blast Furnace Slag (BFS), Basic-Oxygen Furnace Slag (BOFS), Electric-Arc Furnace Slag (EAFS), and Ladle Furnace Slag (LFS), and the type of slag produced is dependent on the desired steel …
copper slag, the huge amount of its annual production is disposed in dumps or stockpiles to date. One of the greatest potential applications for reusing copper slag is in cement and concrete production. Many researchers have investi-gated the use of copper slag in the production of cement, mortar, and concrete as mixed with lime stone powder,
Current regulations in some areas like cement production do not foresee the use of copper slag, even if the slag is very well cleaned. The iron produced in deep …
Given its chemical and mineralogical characteristics, copper slag, a solid industrial by-product, may serve as a partial substitute for silica and hematite in raw mixes used to manufacture Portland cement clinker. The benefits of such substitution include lower production costs and energy savings. The effect of slag-containing raw mixes on …
