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.
Waste as meaningful substitute for natural sand 16th July 2009 14th March 2016 Today, the use of Washed Copper Slag (WCS) as a substitute for sand in the production of concrete is widespread in Singapore with the majority of the Ready Mixed Concrete companies using it.
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.
Eco-concrete uses recycled washed copper slag material and recycled granite to replace up to 50% of the natural aggregates used in concrete production. Copper slag is a by-product of sandblasting at shipyards and recycled granite is from demolition waste. "Star Ready-Mix supports the use of Eco-Concrete for a greener environment"
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.
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. In-depth analysis of 2192 test data sourced from the literature showed that, given all the basic material ...
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 long-term performance enhancements allowing designers to reduce the environmental footprint of concrete while ensuring improved performance and increased durability.
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 self-consolidating concrete (Shoya et al., 2003), high-performance concrete (Al-Jabri, 2006) and high-strength concrete (Khanzadi and Behnood, 2007).
Jan 27, 2017· Concrete was made with a mix design of 1:1.5:3 (1 part cement; 1.5 parts sand and 3 parts coarse aggregate) according to British Standards guidelines for RC40 [].Two different sets of mixes were made with water/cement (w/c) ratios of 0.55 and 0.45 respectively, with the mix composition shown in Table 4.Mixes without copper slag were made to serve as control mixes.
Hi. Copper slag is used in High Performance Concrete. By using the copper slag in concrete as the partial replacement for fine aggregate i.e., sand, the ...
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%, 2.5%, 5%, 10% and 15% replacing Portland cement. Activation of pozzolanic reactions of the pulverized copper slag using 1.5% hydrated lime by weight of Ordinary Portland cement.
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.
14 Magazine of Concrete Research Use of copper slag and washed copper slag as sand in concrete: a state-of-the-art review Lye, Koh, Mangabhai and Dhir Offprint provided courtesy of Author copy for personal use, not for distribution Shi C, Meyer C and Behnood A (2008) Utilization of copper slag slag for JPL Industries ...
copper slag was 2.67 & 2.75 respectively as shown in Table 2.1. The water absorption of 20 mm coarse aggregates, sand &copper slag was found to be 0.609, 1.01 and 0.65 respectively. It was found that water absorption of copper slag was very low as compared with the natural sand and workability of concrete is affected due to it.
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 strength-to-weight ratio, making it an effective option in concrete, or as a fill material under the roadway.
Magazine of Concrete Research Use of copper slag and washed copper slag as sand in concrete: a state-of-the-art review Lye, Koh, Mangabhai and Dhir Offprint provided courtesy of
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.
Use of copper slag and washed copper slag as sand in concrete a state-of-the-art 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 ...
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
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.
In an eco-concrete prototype developed by a ready-mix 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.
