The current paper examines the laboratory testing of various concrete mixes (Mix 20, Mix 40, and Mix 60) containing copper slag waste as a partial replacement for …
slag utilization from various slags are discussed in the book "Metallurgical Slags" [5 ]. The book 'Sustainable Construc-tion Materials—Copper Slag' reviews application options of copper slag in concrete and cement production, geotech-nical applications and road pavements [12]. Reijnders [13]
The mixes containing steel and Fig. 10 System boundary description for cement, fine aggregate, copper slag and steel slag for the present study [46,[64][65][66] [67] 69] copper slag are economical ...
Extensive research efforts are needed to create cost-effective reutilizing and recycling possibilities and to prevent the movement of impurities from waste depositories …
This study reports the potential use of flotation waste of a copper slag (FWCS) as iron source in the production of Portland cement clinker. The FWCS appears a suitable raw material as iron source containing >59% Fe(2)O(3) mainly in the form of fayalite (Fe(2)SiO(4)) and magnetite (Fe(3)O(4)).
One SCM used is copper slag (CS). In this study, a life cycle assessment (LCA) is conducted by investigating the environmental impacts of concrete replacing different percentage of cement with CS.
Experimental Materials. Ordinary Portland cement from Pretoria Portland Cement (PPC) was used for this research study. Coarse aggregates of sizes between 18-20mm size …
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 …
The Sarcheshmeh copper complex belonging to Kerman is one of the biggest copper producers in Iran. Apart from the conventional copper products slag is obtained as a by-product in a quantity of about 1000 t/d. In the past this material was deposited as a waste material on a disposal site. The space for further dumping is limited and the slag causes …
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 …
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 …
Teik et. al. (2006).Copper slag is an industrial by-product material produced from the process of manufacturing copper. For every tone of copper production, about 2.2 tonnes of copper slag is generated. It has been estimated that approximately 24.6 million tons of slag are generated from the world copper industry (Gorai et.
By 2023, the amount of copper mined is anticipated to increase to 28.9 million tons (Chaitanya & Kumar, 2022;Singh et al., 2022). As a byproduct of producing one ton of copper, on average, 2.
Utilisation of slag in cement raw material, Portland cement replacement in concrete, fill and ballast was investigated by (Tixier et al. (1996)). The use of copper slag increased the compressive strength of concrete mixture. Copper slag was used as fine aggregate for concrete by Toshiki et al. (2000). They described the strength, setting time ...
Copper slag (CS) is a by-product from the redox of the metallurgical industry. Copper slag has heterogeneity of metals in its composition, but in general, it …
Abstract. 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.
CS as the core of construction material is to use the silicate in CS to improve the performance of cement by activation (Shi et al. 2008). The application of CS in construction materials mainly ...
and as partial substitute of Portland cement is used copper slag, waste of Laç Copper Plant, Albania. For both materials (cement and copper slag) the chemical composition is determined according to the analytical standard analyses of EN-176 [4]. Several cementing materials are prepared with the optimal copper slag to Portland cement ratio,
