In Belgium, secondary copper slag is produced by a recycling plant. Since this material needs a large area for landfilling, of which the availability is insufficient, and to avoid problems related to the leaching of heavy metals and other harmful elements, it would be interesting to upgrade these ''waste'' products in highvalue applications.
In this study rice husk ash (RHA) and broiler bed ash from rice husk (BBA), two agricultural waste materials, have been assessed for use as partial cement replacement materials for application in lightweight concrete. Physical and chemical characteristics of RHA and BBA were first analyzed. Three ...
high strength performance, copper slag waste material can be used as supplementary cementitious materials (SCMs). The availability of pozzolanic components in copper slag is an interesting phenomenon to study within UHPM. Within the cement and concrete industry, copper slag can be used as cementitious material.
Durability of copper slag contained concrete exposed to sulfate attack ... Copper slag is the waste material of matte smelting and refining ... Past researches of using copper slag in cement and concrete. Properties As supplementary cementitious materials As aggregate replacement
concrete containing copper slag as replacement of fine aggregate, showed significantly increased workability with increase in replacement level. This increase is attributed to the low water absorption of copper slag and its glassy surface (Ayano, 2009). Santharamai and Manoharan (2005) reported that concrete made using fresh ceramic waste as coarse

For these reasons, a possible breakthrough can be sought in exploiting this waste material within cement and concrete production. To apply this idea, secondary copper slag from a Belgian recycling plant is used as supplementary cementitious material and aggregate replacement in UHPC.
Behnood et al. investigated the utilization of copper slag in cement and concrete [21]. Copper slag waste was used as a supplementary cementing material to concrete by Moura et al. [22]. The key ...
partial replacement of fine aggregate with copper slag. Addition of copper slag increases the density of concrete thereby increasing the selfweight, so that it can be used for high density concrete production. Economic Feasibility Geopolymer concrete (GPC) manufactured using industrial waste like fly ash, GGBS and copper slag is
Main objective of this experimentation is to study the effect of alternate wetting and drying on concrete produced by replacing natural coarse aggregates by recycled aggregates and on recycled aggregate concrete with different supplementary cementitious materials. The grade of concrete adopted is M20, as it is the widely used structural concrete.

The results pointed out that there is a potential for the use of copper slag as a supplementary cementing material to concrete production. The concrete batches with copper slag addition presented greater mechanical and durability performance.
The utilization of solid waste is the challenge for the civil and environmental engineers to utilize the waste from different industry to excel the sustainable development, and in the same time, it is matching with the cost concern of the present materials. Copper slag is a byproduct obtained during smelting and refining of copper.
(CBA), steel slag, copper slag and FNS are the most frequently studied materials because they are produced in considerable quantities. Aggregate plays a vital role on all concrete properties such as workability, strength and durability. The use of coal bottom ash as fine aggregate was found to reduce compressive and tensile strengths of con
