investigate the performance of copper slag in self compacting concrete as partial replacement of fine aggregate. Therefore, it is recommended that 40% of copper slag can used as replacement of sand in order to obtain HPC with good strength and durability properties.
This research was undertaken to study the effect of copper slag (CS) and cement bypass dust (CBPD) addition on concrete properties. In addition to the control mixture, two different trial mixtures were prepared using different proportions of CS and CBPD.

It has been observed by them that addition of copper slag improved the density of the concrete together with rapid increase in the workability. Also, they have noted that up to 40% replacement of fine aggregate by copper slag would yield High Performance Concrete with good strength and durability.
Use of copper slag and washed copper slag as sand in concrete a stateoftheart review. Chao Qun Lye, Siew Kiang Koh, Raman Mangabhai, Ravindra K. Dhir ... CS/WCS can be used as the sand component for making all strength grades of concrete and giving similar (or in some aspects better) performance to the corresponding concrete made with ...
How is copper slag used for construction? Quora. Apr 19, 2018· Copper slag can be used in concrete production as a partial replacement for sand. Copper slag is used as a building material, formed into blocks. Copper slag also has a high strengthtoweight ratio, making it an effective option in concrete, or as a fill material under the roadway.
In an ecoconcrete prototype developed by a readymix concrete supply company, Holcim (Singapore) Pte Ltd, recycled aggregates from demolition waste were used to replace of the natural coarse aggregates while washed copper slag substitute 70% of the natural sand component.
• Concrete using Ground Granulated Blast Furnace Slag and OPC • Nonstructural Concrete using Washed Copper Slag/Recycled Aggregates • Ultra High Performance Concrete of above 100mpa • High Density Concrete • Light Weight Concrete • Pavement Quality Concrete • Shotcrete • Colored Concrete • Temperature Controlled Concrete
Good performance of copper slag as fine and coarse aggregates in normal concrete is the basis for researchers to evaluate its possible use in producing special concrete such as selfconsolidating concrete (Shoya et al., 2003), highperformance concrete (AlJabri, 2006) and highstrength concrete (Khanzadi and Behnood, 2007).
Turning Black Into Gold Singapore Copper Slag Story It was all started in early 2007 when Indonesia banned sand exports over environmental concerns. Construction was hit hard by the skyrocketing prices resulting from concrete supply disruptions due to unavailability of sand.
Copper slag is successfully used as partial replacement for river sand used in concrete and mortar production. Concrete and reinforced concrete are more resistant and durable over time when adding copper slag, being recommended in bridges pillars manufacturing, building blocks, construction etc.
Copper slag as sand replacement for high performance. It is recommended that 40 wt% of copper slag can be used as replacement of sand in order to obtain HPC with good It should be noted that further research work is needed to explore the effect of copper slag as fine aggregates on the properties of concrete with different cement ...

Copper slag as sand replacement for high performance concrete by ... Copper slag as sand replacement for high performance concrete by: Khalifa Al ... may also use copper slag in place of sand during concrete construction. ... resulting from the copper manufacturing process and help in saving natural resources.
performance of copper slag on strength properties as partial replace ... research work, M25 grade concrete was used and tests were conducted for various proportions of copper slag replacement with sand of 0 to in concrete.
Performance Characteristics of Copper and Coal Slag Abrasives By John Peart, and Benjamin Fultz, Bechtel Corporation Abrasives processed from slags have replaced silica sands in many steel fabrication shops because of their low free silica content. Copper smelters and coalfired electric generating plants are 2 major material sources for
Generally, the conventional concrete constituents, namely Portland cement, granite and concreting sand, were partially substituted by ground granulated blastfurnance slag, recycled concrete aggregate, washed copper slag and manufactured sand at their respective replacement levels.
At the same time, finding the optimum suitable amount of blasted and washed copper slag in concrete making without affecting the strengths of the concrete, that is at e same time ensure percentage of copper slag in concrete forming would take the variation in compounds in the copper slag into consideration, therefore making the end product ...
While there are many applications and benefits of slag cement, a few are highlighted below and detailed information sheets are located here. The use of slag cement has demonstrated longterm performance enhancements allowing designers to reduce the environmental footprint of concrete while ensuring improved performance and increased durability.
silicate hydrate, which eventually densifies the interfacial transition zone, thereby improving the performance of concrete. (Moura et al., 2007) Utilized industrial waste, including fly ash, ground granulated blast furnace slag, silica fume, and copper slag, which could function in a similar manner as cement. (Poon et al., 2000) An
Aug 20, 2014· Abstract. 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.

Copper slag (CS) and washed copper slag (WCS), as to be expected, have essentially similar basic physical (although WCS is usually finer than CS) and chemical characteristics and therefore they can be treated as one material. Indepth analysis of 2192 test data sourced from the literature showed that, given all the basic material ...
A series of concrete mixtures were cast in cubic moulds of size nominal size 100 mm with different proportions of pulverised copper slag ranging from 0%, %, 5%, 10% and 15% replacing Portland cement. Activation of pozzolanic reactions of the pulverized copper slag using % hydrated lime by weight of Ordinary Portland cement.
