Copper slag as cement replacement Several Studies have been reported on the hydration reactions (Mobasher & Devaguptapu 2000) and pozzolanic properties (Arino & Mobasher 1999) of copper slag up to 15% by weight replacement for Ordinary Portland cement. The conclusion made was, the use of
The compressive strength of cube specimen for different copper slag content as a replacement of sand at 7, 28, and 56 days curing period respectively is presented below. These results show an increasing profile up to 40% replacement of copper slag and then it shows decreasing profile as more copper slag
This paper reports on an experimental program to investigate the effect of using copper slag as a replacement of sand on the properties of high performance concrete (HPC). Eight concrete mixtures were prepared with different proportions of copper slag ranging from 0% (for the control mix) to 100%.
20-8-2014· 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
The use of copper slag in the concrete industry as a replacement for cement can have the benefit of reducing the costs of disposal and help in protecting the environment. Despite the fact that several studies have been reported on the effect of copper slag replacement on the properties of Concrete, further investigations are
To study the effect of copper slag substitution as a replacement for fine aggregates on the strength of cement mortars, specimens were prepared with different percentages of copper slag (by weight). The percentage of copper slag added were as follows: 0% (for the control mix ), 20%, 40%, 50%, 60%, 80% and 100%. Cubes (70.6
Copper slag as fine aggregate for high performance concrete K. S. Al Jabri From mortar strength tests with a cement/slag/water ratio of 1/2/0.55, to study the effect of copper slag replacement on the workability of concrete.
4) However, further additions of copper slag caused reduction in the strength due to an increase of the free water content in the mix. 5) Mixtures with 0% and 100% copper slag replacement gave the lowest compressive strength value of Approximately 30 MPa, which was

Most of the properties of the concrete depend on cement. Cement is Find, read and cite all the research you need on ResearchGate
One of the greatest potential applications for reusing copper slag is in cement and concrete production. Many researchers have investigated the use of copper slag in the production of cement, mortar and concrete as raw materials for clinker, cement replacement, coarse and fine aggregates.
use of copper slag as a replacement for fine aggregate is investigated. Three slender reinforced concrete columns of 150x150x2500mm were tested for monotonic axial compression load until failure. The concrete mix included ordinary Portland cement, fine aggregate, 10mm coarse aggregate and copper slag. The ratios of copper slag to fine aggregate
copper slag as partial replacement of aggregate to control the amount of bleeding to less than 5 l/m. 2. Studies by Alnuaimi indicated that replac e-ment of fine aggregate (sand) by copper slag does not have an adverse effect on the load carrying capacity of the concrete columns. Rojas  had reported that copper slag exhibits

Many researchers have investigated the use of copper slag in the production of cement, mortar and concrete as raw materials for clinker, cement replacement, coarse and fine aggregates. The use of copper slag in cement
use of copper slag for fine aggregate in concrete specimens. 3. To inspect the performance of concrete made with copper slag as replacement of fine aggregate. 4. To evaluate the compressive, tensile and flexural strength of concrete by using copper slag in concrete specimens. 3. MATERIALS USED 3.1. Cement:
with copper slag shows an increase of 34% when compared to conventional concrete. 3. T. Ch. Madhavi (2014) Copper Slag In Concrete As Replacement. The researchers found in his experiment that the copper slag is an industrial waste which can be used as a replacement for cement
mixes with copper slag gave concrete with adequate properties, with the optimal sand replacements by water-cooled copper slag overall being in the region of 30-60%. Based on the results water-cooled copper slag can be considered to be a suitable candidate for the partial replacement

The percentage of copper slag used for replacement of river sand are 0%, 10%, 20%, 30%, 40%, 50%. Cement sand mortar joint thickness of 10 and 15mm. Plaster ability of use of copper slag for partial replacement material for river sand. Use of copper slag as replacement material for river sand in cement concrete.

Influence of Copper Slag in Concrete as Partial Replacement for Fine Aggregate N. Vinoth Kumar1 S. K. Divya2 A. Sattainathan Sharma3 1,2,3Assistant Professor 1,2,3Department of Civil Engineering 1,2,3Valliammai Engineering College, Kancheepuram, India Abstract—Concrete is the widely used construction material.
ordinary Portland cement. The use of copper slag reduces the early age strength (1 day) while increasing it beyond 7 days . The use of ground copper slag up to 15% by mass as a Portland cement replacement increased the strength significantly . The addition of copper slag to cement increasedits initial and final setting times .
Copper slag is the Strelite industry waste obtained from smelting and refining process of copper at larger rate. Nearly 4-5 tons of copper is obtain as waste slag which contain pozzolonic property and have high density can be used as replacement for all concrete materials like sand, cement and coarse aggregate.
